• Adhesive tape

Anisotropic conductive film (ACF) is a film material used to mount electronic components such as ICs onto substrates and to form circuits. It was commercialized in 1977 by Sony Chemical, the predecessor of Dexerials, and is now used as a material for circuit bonding in almost all digital devices that utilize flat panel displays, such as smartphones, tablet PCs, and high-definition televisions. To display images on a display screen, it is necessary to electrically connect the IC chip to the glass substrate of the display and form numerous electronic circuits. ACF is used for that connection. Currently, ACF is commonly used in the mounting method called "COG mounting," which connects IC chips to glass substrates, and in "FOG mounting," which connects flexible printed circuits to glass substrates. Additionally, ACF is utilized in camera modules such as CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide-Semiconductor), as well as in the circuit connection parts of contactless IC cards. *For more detailed information, please refer to the related links.

Our optical transparent resin, marketed under the name SVR, is a resin that combines optical properties and elasticity. Its main application is as a liquid adhesive material used to fill the air gap between the top plate (glass or resin) of displays, such as those found in smartphones and tablet PCs, and the modules underneath, like liquid crystal displays (LCDs). The primary advantage of SVR is its ability to significantly improve visibility. By filling the air gap, reflections of external light at the top plate interface and the diffusion of internal image light are minimized. In previous mobile phones, a phenomenon occurred where the visibility of the display deteriorated due to the difference in refractive index between the top plate and the air within the air gap when external light entered. By filling the air gap with SVR, which has the same refractive index as the top plate, there are no points where refraction occurs, allowing external light to reach the LCD directly. *For more detailed information, please refer to the related links.

In this article, the General Manager of the Automotive Solutions Sales Department at our Global Sales & Marketing Headquarters will explain the adhesive technology that achieves high precision for in-vehicle sensing cameras. In recent years, more and more vehicles have been equipped with advanced driver assistance systems (ADAS) such as automatic braking when a danger is detected and the ability to maintain lane while following the car in front, categorized as Level 1 and Level 2. Essential for realizing these ADAS features, as well as the more advanced Level 3 and above autonomous driving functions expected to become widespread in the future, is the "in-vehicle sensing camera." Many recent cars have cameras mounted on the rearview mirror located in front of the windshield inside the cabin, and there is a growing number of models that also include cameras mounted on the front, rear, and sides of the vehicle. As the technology for ADAS and autonomous driving continues to spread, the demand for in-vehicle sensing cameras is expected to increase, with projections indicating that it will more than double over the six years from 2020 to 2026. *For more detailed information, please refer to the related links.

• Vehicle body parts

Anti-reflective film is a type of film designed to suppress the reflection of external light on the surface of optical devices such as displays, aiming to prevent a decrease in visibility. Generally, it has a structure where a thin, transparent film with anti-reflective optical properties is layered on the surface of a base film. For example, the sparkling appearance of a water surface is due to the difference in refractive indices between air and water, which causes some light to be reflected at the boundary. Since the surface of a display also has an interface with air, light reflection will inevitably occur even if the display is covered with a transparent glass cover. Anti-reflective film is designed to minimize this reflection as much as possible. Our anti-reflective film consists of an adhesive layer, a base film, a hard coat layer, and an anti-reflective layer, with an anti-fouling treatment applied to the outermost surface. By controlling the refractive indices and thicknesses of the materials that make up the layers so that the phase of the interface reflection light reflected at each membrane interface cancels out the phase of the surface reflection light reflected at the surface, it is possible to reduce the reflected light. *For more detailed information, please refer to the related links.

There are several methods for forming thin films on the surfaces of substrates such as film and glass, including coating, printing, plating, and vapor deposition. However, the technique used to accurately form nano-level thin films composed of metals or ceramics is called "sputtering." In actual sputtering, the role of the "stone" is played by inert gases such as argon (Ar) that are filled in a vacuum container (vacuum chamber). In sputtering, argon gas is introduced into the vacuum, and a negative voltage is applied to the target material, generating a glow discharge, which is also used in fluorescent lights. The positively charged, plasma-formed argon ions then collide with the surface of the target material at ultra-high speeds (about 3.2 km per second), violently ejecting particles (atoms and molecules) from the target material. The ejected particles adhere vigorously to the surface of the substrate, and as they accumulate, a thin film is formed. This is the principle of sputtering. *For more detailed information, please refer to the related links. For further inquiries, feel free to contact us.*

• Sputtering Equipment

The "inorganic diffusion plate" sold by Dexerials is primarily used as a component to diffuse the light from laser light sources in projectors. One of the significant technological innovations that has occurred in projectors in recent years is the transition of the light source from mercury lamps to laser light. Instead, lasers are increasingly being used as the light source for projectors. As can be seen with laser pointers, laser light is highly directional and does not spread much on its own. This is in stark contrast to the light from mercury lamps, which naturally spreads in all directions, so it is necessary to diffuse the light for use as a projector light source. To achieve this, "diffusion plates," including our products, are used. While there are diffusion plates made from organic materials, those designed for projectors often use inorganic diffusion plates due to their ability to withstand heat generated by laser light over extended periods. *For more detailed information, please refer to the related links.

Moths, which are nocturnal insects, can freely fly around in the dark of night while protecting themselves from predators. To find food sources such as nectar and tree sap, they have evolved a special eye structure known as "moth-eye." The surface of a moth's compound eye is lined with numerous tiny protrusions at the nanoscale, arranged at regular intervals. This structure allows the eye to capture faint light with almost no reflection. The protrusions that form the moth-eye structure are smaller than the wavelength of visible light and are arranged in a regular pattern. The reflection of light in the atmosphere occurs due to differences in the refractive index between air and the material it encounters. However, the protrusions in the moth's eye are shaped like curved spindles, allowing them to capture incoming light from various angles while continuously changing the refractive index, resulting in minimal light reflection from the moth's eye. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

The film used for regular medical shields is a transparent film such as PET. While there are no issues regarding protection from splashes, there are several challenges when considering its use in medical settings, especially in operating rooms. Generally, PET film has a transparency of about 90% and a light reflection rate of around 8%. While this may not be bothersome for short periods, prolonged use of face shields can lead to eye fatigue due to glare (light reflection from the film). A few years ago, we heard from a doctor at a hospital who said, "The current protective gear (eye shields and face shields) is difficult to use because of light reflection. Is it possible to create a more user-friendly shield by applying Dexerials' anti-reflective film?" This prompted us to start developing a high-transparency, anti-reflective film suitable for medical shields. This article will explain the features of medical shield materials that apply the anti-reflective Moss Eye type film. *For detailed content of the article, please refer to the related links.

Dexerials' proud "roll-to-roll imprinting technology" is a technique that continuously forms fine structures ranging from several hundred nanometers to several hundred micrometers in size on films extending over hundreds of meters in length. Our company possesses two technologies for creating the master plates used to transfer fine structures onto film substrates: "lithography processing" and "precision machining." The surface of the cylindrical substrate is coated with a resin called resist, and after a laser light draws a pattern on the resist with a pre-calculated movement, a treatment called dry etching is applied, where plasma gas is used to form fine structures. Lithography processing can engrave intricate patterns on the master plate at the nanometer scale. The other method for creating the master plate is precision machining using machinery. In this process, a metallic cylindrical substrate is rotated while being cut with high-hardness bits (cutters) such as diamonds to form fine structures on the surface. *For more detailed information, please refer to the related links. For further inquiries, feel free to contact us.*

• Printing Machinery

Dexerials' microfabrication technology is a technique that forms fine structures of various sizes and patterns, ranging from several hundred nanometers to several hundred micrometers, by either engraving the surface of substrates such as films, resin sheets, and glass, or by stacking materials. By creating complex microstructures on the surface of substrates based on meticulous calculations, it imparts useful functions such as controlling light reflection. This is made possible by our unique imprinting technology that employs a roll-to-roll method. The "roll-to-roll method" refers to a production process where substrates, such as films that are several hundred meters long and rolled up, are processed while being fed through, and then rolled back up again. While there is also a "batch method" that processes flat substrates, the roll-to-roll method we use is known for its high efficiency as it can continuously process very long materials. *For more detailed information, please refer to the related links.

Dexerials has developed numerous new functional materials and devices, primarily in the field of electronics. One of these is an anti-reflective film that utilizes microstructures. On the surface of a moth's eye, there are regularly arranged protrusions that are smaller than the wavelength of visible light (380nm to 780nm). The area near the tips of these small protrusions appears as if it does not exist to the light entering the moth's eye. For moths, which are primarily active at night, external light reflection in their eyes increases the risk of being detected by predators. At the same time, it is believed that they have evolved this eye structure to navigate without colliding with obstacles even in the faint moonlight at night. The "Moth Eye Type Anti-Reflective Film" developed and manufactured by our company is a product that forms this microstructure on the surface of the film. It features an overwhelmingly low external light reflection rate and high light transmittance compared to conventional films, making it useful in various fields such as display anti-reflection and medical shields due to its low reflection properties. *For more detailed information, please refer to the related links.

The head-up display (HUD), which is increasingly being installed in luxury cars, utilizes a "diffusion micro-lens array" developed by Dexerials to improve image quality. This component is used inside the HUD, which is becoming more common in recent automobiles, and it functions to increase the brightness of the images projected onto the windshield and reduce display unevenness. In Japan, it is referred to as a "diffusion plate." The HUD conveys information to the driver by projecting images onto the front windshield of the driver's seat using a projector. In current automobiles, it serves as a complement to traditional display-type car navigation systems, but its development has been led by European car manufacturers. *For more detailed information, please refer to the related links.

High-performance displays are no longer uncommon in digital devices surrounding our lives, including smartphones, tablet PCs, and automotive navigation systems. Moreover, recent displays have shown evolution beyond the traditional rectangular shape. It is expected that the trend of increasing curved and irregular displays will continue in the future, which is why Dexerials has been working on developing new technologies aimed at enhancing the freedom of coating shapes for SVR. The result of these development efforts is "Jettable SVR." This can be applied to cover plates using inkjet technology. Similar to home inkjet printers that can print photos on New Year's cards, design data for the desired coating shape is created in advance on a computer. The advantage is that it can be applied with high precision in the exact shape as designed. *For more details, please refer to the related links. For further inquiries, feel free to contact us.

Our anti-reflective film "AR100 Series" achieves high effectiveness in reducing light reflection and diffusion when applied to display covers, making it a choice for many manufacturers of monitors, tablet PCs, and in-vehicle displays. Additionally, the optical transparent resin (OCR/LOCA) used to bond the surface panel (top plate) of display products to the display module is a material that suppresses light reflection and refraction at material boundaries. Recently, a new addition to our optical product line is the "Anti-Reflective Film Moss Eye Type." The surface of a moth's eye has regularly arranged nano-level protrusions that allow it to absorb incoming light with minimal reflection. At Dexerials, we have successfully created a structure similar to that of a moth's eye on a resin film using our unique manufacturing method. By applying this to displays, we have established a technology that achieves high anti-reflective effects and improves contrast. *For more detailed information, please refer to the related links.

In recent years, automotive manufacturers and Tier 1 suppliers have been focusing on enhancing the functionality of in-vehicle displays to make driving more comfortable. Traditionally, in-vehicle displays were mostly flat and rectangular in shape, but recently, there has been progress in developing displays with gently curved surfaces that conform to the shape of the interior, as well as non-rectangular displays known as "free-form." With the development of these new displays, there has been a growing demand for new technologies in "optical bonding," which involves adhering the display and the protective cover component together. "Optical bonding" refers to the process of bonding a display module, such as a liquid crystal panel, with a cover (top plate) using optically transparent materials. Typically, glass or acrylic sheets are used for the top plate, but if there is an air gap between the display and the cover, differences in refractive index can cause image blurring and reduced brightness. *For more detailed information, please refer to the related links.

In recent years, automobile users have been seeking stylish interior designs that match the excellent exterior designs of their vehicles. Particularly among those who prefer luxurious designs from Europe and the United States, there has been an increasing number of people who favor interiors with a "piano-like deep glossy black" (piano black). This makes the appearance of displays, which are used for various purposes, particularly important. Recently, many displays have been utilized in car navigation systems and other applications. On the other hand, displays that can express a beautiful "piano black" that harmonizes with the surrounding interior, such as the dashboard, during both power on and off have been difficult to achieve due to technical hurdles. Our company has been advancing the research and development of "anti-reflective films" that enable displays with a luxurious "piano black." The foundation of this research is the anti-reflective technology used in high-grade PC monitors and tablet PC displays. This black is achieved by not reflecting light. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

While walking in the city, you may come across cars with yellowed headlights, which is caused by degradation due to ultraviolet (UV) rays. The resin used for the headlight covers, such as polycarbonate, undergoes chemical changes when exposed to UV rays for extended periods. For this reason, UV protection is very important in interior design as well. Displays used in car navigation systems may also change appearance due to UV rays. Therefore, design considerations are made to prevent direct sunlight exposure by installing sunshades or adjusting the installation position and angle. Dexerials proposes anti-reflective films for automotive displays, which suppress sunlight reflection and enhance visibility. This allows for smaller sunshades and greater flexibility in installation position and angle, making interior design more versatile. This article will focus on the technical approach to the adhesive layer of anti-reflective films. *For more detailed information, please refer to the related links.

Functional adhesive tapes used in smartphones and tablet PCs not only secure components but also possess various special functions. It is not an exaggeration to say that without functional adhesive tapes, it would be impossible to produce digital devices due to features such as conductivity, waterproofing, shock resistance, light shielding, and thermal conductivity. The adhesive used in Dexerials' functional adhesive tapes is primarily made from acrylic materials. While there are also rubber-based and silicone-based adhesives, acrylic adhesives offer excellent advantages such as "superior heat resistance and weather resistance," "a wide range of substrates," and "relatively low cost." There are two production methods for acrylic-based adhesives: one using organic solvents and the other curing with ultraviolet (UV) light. In the method using organic solvents, it is difficult to achieve a thicker adhesive layer because the solvent must be dried and evaporated, which reduces the volume. However, the UV method does not require drying, allowing for a significantly thicker adhesive layer of about 2mm. *For more detailed information, please refer to the related links. Feel free to contact us for more information.*

• Adhesive tape

The use of adhesive tape produced by chemical manufacturers such as Dexerials is rapidly increasing as a substitute for screws. What is the reason for using screws to secure parts in the first place? It is because screws allow for "disassembly without damaging the parts if necessary, even after they have been secured, and can be re-secured." This is referred to as "reworkability" in production environments, and due to the improved functionality of adhesives and adhesive tapes, they are now being adopted in places where reworkability is required. Unlike screws that secure at a "point," adhesive tape can be cut into a continuous shape, allowing for stable fixation of parts over a "surface." Additionally, when using screws, a process to create screw holes is necessary, and to accommodate the full length of the screw, a "thickness" is required in the casing. In contrast, adhesive tape can be easily adjusted in thickness and shape, accommodating a wide range from below 10 microns to several hundred microns in thickness. *For more detailed information, please refer to the related links.

In this article, we will discuss the liquid properties and cured properties of adhesives in the order of changes in their state. Liquid water changes its shape flexibly when force is applied. Water placed in a cup fills the interior shape of the cup without gaps due to gravity, and the top takes on a horizontal shape. Liquids for which the "applied force" and the "amount of deformation" are in a proportional relationship, like this water, are called Newtonian fluids. On the other hand, liquids like mayonnaise have different properties than water. Mayonnaise on a plate does not spread horizontally like water; instead, it mounds up and takes on a solid-like shape. Liquids that have the property of changing viscosity depending on the applied force, like this mayonnaise, are called thixotropic liquids. Generally, materials commonly used for adhesives are also thixotropic liquids. High thixotropic liquids behave like solids when little force is applied, and they change into a liquid like water when a large force is applied. Moreover, the higher the thixotropic nature of a liquid, the greater its ability to maintain shape. *For more detailed information, please refer to the related links.

The dentist fills the cavity in the tooth with a soft paste-like "resin," and when they press the switch on the machine placed in the mouth, it hardens in an instant. In fact, that machine is a UV irradiation device. The "UV-curable adhesive" developed by DEXERIALS also hardens and bonds parts together in a similar manner to the dentist's resin by exposing it to UV light. There are other types of adhesives that harden by applying heat, but the advantages of UV-curable adhesives are as follows: 1. Quick curing: Adhesion can be achieved in just a few seconds. 2. Low damage: Can be applied to substrates with low heat resistance. 3. Space-saving: No need for large heating furnaces required for thermal processing. 4. Low odor: Does not use organic solvents. 5. Safety against heat: Processing with light ensures high safety for workers. 6. Energy-efficient and low-cost: Long-lasting LED light sources are used. 7. Pinpoint curing: Allows for localized adhesion by irradiating UV light in a narrow area. 8. Excellent abrasion resistance: Can achieve a high-quality appearance. *For more detailed information, please refer to the related links. Feel free to contact us for more details.

Dexerials produces and sells two types of tapes: "adhesive tape" and "bonding tape." Literally, adhesive tape has "adhesive" applied to a core material or film, while bonding tape has "bonding agent" applied. The adhesive is required to gently hold parts in place compared to the bonding agent, and it is characterized by the ability to be removed even after being applied. In contrast, the bonding agent is designed to hold parts more securely and is generally not meant to be removed once applied. In addition to bonding strength, there are the following differences between bonding tape and adhesive tape: - The adhesive in adhesive tape does not change its properties before and after application, while the bonding agent in bonding tape hardens and changes its properties due to stimuli such as temperature, humidity, and ultraviolet light. - There is a difference in the freedom of shape of the adherend. - Bonding tape holds the adherend more securely, resulting in less deformation or displacement due to stress. - The heat resistance after bonding and adhesion differs (bonding tape can maintain its bonded state at high temperatures compared to adhesive tape). - The storage temperatures are different. *For more detailed information, please refer to the related links.

"Adhesion" and "stickiness." These are terms we often hear in daily life, but do you know the exact differences between them? The "adhesives" and "adhesive agents" produced by DEXERIALS have the same function of sticking (fixing) objects together. Therefore, stickiness is classified as a type of adhesion, but the difference lies in that adhesives achieve strong fixation, while adhesive agents allow for a more gentle fixation. When you adhere object A to object B, if you try to forcibly peel them apart, ultimately either A or B, or both, will break. In contrast, when it comes to stickiness, if you attempt to peel them apart, the adhesive that is sticking A and B together will break, but A and B will remain intact and can be reused in their original state. The reason components like smartphone touch panels are fixed with adhesive agents instead of adhesives is to take advantage of this property. By using adhesive agents, even after peeling the components apart during repairs, you can restore them to their original condition by using the adhesive agent again. *For more detailed information, you can view the related links.
