This processing technology is suitable for materials under consideration for differentiation and those that are stagnant, leading to the birth of new materials through D-ALIGN processing. It is a recommended processing method for those considering material development.

SSG Coat can be applied using spray, spin coating, or brush application, and is suitable for various materials such as metal, wood, concrete, and resin. - The coating agent is a moisture-curing material that hardens at room temperature, eliminating the need for heating devices or UV irradiation equipment. However, curing takes several hours to several days. - The coating film has high adhesion to the substrate and demonstrates excellent scratch resistance, stain resistance, and solvent resistance. It creates a flexible coating film that also excels in substrate conformity. - It provides a transparent coating film that allows for a painted finish that enhances the material feel (such as wood texture or metallic feel). SSG Coat is a coating agent that can be used without limiting the materials it can be applied to, and its application in various fields and new uses is anticipated. Please check its potential.

Nittobo’s "Glass Cloth Dot" is an innovative new material featuring a uniform dot-pattern coating of hot-melt resin on the surface of glass cloth. It significantly suppresses "fraying," "weave misalignment," and the generation of "glass fuzz (dust)" during cutting and processing—common challenges with conventional glass cloth. This reduces the burden on operators and contributes to maintaining a clean working environment. The most significant feature is its self-adhesive function via heating. This prevents shifting during the layering process and makes shaping to the mold easier, strongly supporting shorter working times and labor savings. The amount and spacing of the hot-melt material can be optimally adjusted according to the application. This ensures product quality stability and improved impact resistance without compromising resin impregnation. It provides the ideal solution for modern composite molding sites where productivity improvements and advanced quality are required.

Nittobo's "Low-Dk Glass Cloth" is a product made from specialized glass fibers with a lower dielectric constant (Dk) and dissipation factor (Df) compared to conventional E-glass. In modern communication and radar technologies, the radio wave permeability of components is crucial. By using this product as a reinforcing material for FRP (Fiber Reinforced Plastics), it is possible to significantly enhance the radio wave permeability of communication-related components, such as radomes.A key feature of this material is its ability to maintain processability and mechanical properties nearly identical to those of standard E-glass cloth, while providing superior electrical characteristics. It also shows excellent compatibility with various resins, including epoxy and cyanate ester resins, allowing for integration using existing molding processes. This high-performance material offers a new solution for demanding environments—such as next-generation high-speed communications and the aerospace industry—where both precise signal transmission and high structural strength are required.

Nittobo’s "High-Strength Thin GFRP" is a next-generation functional material utilizing our independently developed high-strength glass fiber (GF) as a reinforcement. This high-strength GF is characterized by its superior strength and high elongation compared to conventional glass fibers. By applying this fiber, the mechanical properties of the GFRP are dramatically improved, achieving levels of strength previously unreachable with standard GF products. Developed with the core keywords of "Metal Replacement," "Weight Reduction," "High Strength," "Thin-walling," and "Insulation," this product supports the extreme thinning of components while maintaining high tensile and flexural strength. For designers seeking strength comparable to or exceeding metal in a lightweight form, this is a breakthrough solution that dramatically expands the freedom of structural design, from aerospace to everyday electronic devices.

Nittobo’s "Commingled Glass Cloth" is an innovative composite material created by twisting and weaving high-strength "glass fibers" with thermoplastic "organic fibers (plastic fibers)" using proprietary technology. Its greatest feature lies in "one-shot molding," which allows products to be manufactured using only heat and pressure. Since the resin is already uniformly mixed with the fibers, the material exhibits exceptional mold-following capability and impregnation. This allows for the precise molding of deep-drawn shapes and complex contours—previously difficult to achieve—in a single process. Consequently, it strongly supports a dramatic shortening of manufacturing steps, cost reduction, and labor savings. Furthermore, by leveraging the properties of thermoplastic resin, post-molding reprocessing and recycling are made easy, contributing to a reduced environmental footprint. While lightweight, it possesses high reaction force and superior impact resistance that surpass aluminum, providing a new standard for manufacturing sites where both strength and productivity are required.

Nittobo’s "GFRP with Visible Weave" is an entirely new decorative composite material developed by precisely adjusting the refractive indices of glass fibers (GF) and the matrix resin. Its greatest feature lies in achieving a sense of transparency and the natural luster of the fibers themselves—a combination previously difficult to balance in conventional FRP. The fiber bundles encapsulated within the resin strongly scatter and reflect light, causing them to appear brilliant. After molding, the glass cloth's weave pattern emerges as a three-dimensional texture, creating a deep 3D effect as if the pattern is floating deep within the resin. While enabling new design expressions that highlight the original beauty of the weave, this next-generation material also firmly maintains the electrical insulation and radio wave permeability inherent to GFRP. It adds transparency and a high-end aesthetic to products without compromising functionality.

Nittobo’s Glass Fiber Reinforced Transparent Material (developmental product) is a next-generation composite that fuses the structural strength of glass fiber with the superior light transmittance of transparent resin. Conventional FRP (Fiber Reinforced Plastics) faced the challenge of becoming opaque due to light reflecting at the interface where the refractive indices of the resin and glass fiber differ. This product achieves unprecedented levels of transparency by utilizing precision control technology to match the refractive indices of both materials to the limit, thereby suppressing interface reflection. The greatest advantage lies in simultaneously overcoming the lack of strength in transparent plastics and the brittleness/fragility of tempered glass. While being lightweight, it possesses high rigidity and "toughness" that prevents shattering upon impact, making it suitable for structural components where safety is paramount. This high-performance material resolves the design dilemma of requiring light transmission without compromising strength, expanding possibilities as a tough, lightweight alternative to glass and acrylic.

Nittobo’s glass fiber reinforced plastic (GFRP) screws are high-performance fastening components made of resin reinforced with long glass fibers. The most significant feature is their overwhelming lightness—less than one-third the weight of metal screws—while achieving superior strength through long-fiber reinforcement. This allows for drastic weight reduction by replacing conventional steel bolts. Functionally, these screws leverage the natural properties of GFRP to provide excellent electrical insulation, enhancing safety in electrical and electronic applications. Being non-metallic, they are completely free from rust and corrosion, ensuring a long service life even in harsh environments exposed to water or chemicals. Furthermore, they eliminate the issue of "galvanic corrosion" typically encountered when joining dissimilar metals, offering a highly reliable joining solution for multi-material designs. From mobility sectors aiming for improved fuel efficiency to infrastructure equipment, this developmental product brings innovation to every single bolt.

Nitto Boseki's "Plastic Reinforcement Recycled Glass Fiber" is an innovative environmentally friendly material that contributes to sustainable manufacturing and the realization of carbon neutrality. Currently, we are promoting product development through two approaches. The first is the "mass balance approach product" certified by ISCC PLUS, which has a manufacturing scheme that reduces environmental impact and achieves a 100% recycling rate (defined value), allowing for a smooth replacement of conventional existing products. The second is the "PCR (Post-Consumer Recycled) product," which uses cover glass from used solar panels, raising concerns about future environmental impact as waste. Through Nitto Boseki's advanced surface treatment technology and appropriate adjustment of recycling rates, we have successfully achieved excellent mechanical properties equivalent to virgin products (standard products). We provide a next-generation composite solution that maintains the high reinforcement performance of conventional glass fibers while directly contributing to the reduction of the product's carbon footprint (CFP).
