This is a non-cyanide silver plating bath that does not use cyanide compounds. By not using toxic substances such as cyanide compounds or selenium, it reduces the risk for operators and in the event of a leak. Additionally, since it is not a toxic substance, strict chemical management and special wastewater treatment facilities are not required. With a wide range of products available, we can offer various options tailored to our customers' needs.

• Chemicals

It is a vapor-phase rust preventive agent that suppresses rust, oxidation, and sulfide on metals before and after plating. - It works simply by placing it in a sealed space with the metal you want to protect. - Since the vapor-phase components form a thin protective film on the metal surface, there is no need for application like rust prevention oil, and it does not create stickiness, reducing the burden on the degreasing tank before plating and minimizing impact on subsequent processes after plating. - It can be applied in transport boxes, as it is effective even without complete sealing, similar to desiccants like silica gel or oxygen absorbers. - Because the vapor-phase components dissolve in water, it maintains a certain level of effectiveness even if condensation occurs.

Recently, there has been an increasing demand for materials with blue light cut performance (410nm cut performance) for applications such as eyewear and electronic materials. However, it is common for materials targeting this wavelength to have absorption capabilities that extend into the visible light range, which can affect the color tone of the final product. This product is a material that can suppress coloring by enhancing material purity while maintaining absorption capabilities above 410nm. It enables the design of films and optical lenses that provide 410nm protection for the material while maintaining the aesthetic appearance of the product.

• Other polymer materials

Recently, the demand for polyester and polycarbonate with blue light cut performance for applications such as eyewear and displays has been increasing. Generally, these resins are molded by melt mixing at high temperatures of around 300°C. When adding UV absorbers to the resin, it is common to add them during the mixing process; however, in the case of organic UV absorbers, the decomposition temperature is often below 300°C. Therefore, there are few UV absorbers that can withstand temperatures above 300°C. Our product has heat resistance above 300°C, allowing for direct melt mixing with materials that require temperatures above 300°C for molding, similar to the aforementioned resins. As a result, it is possible to impart blue light cut performance directly to the resin itself.

• Other polymer materials

Recently, with the spread of smartphones and tablets, as well as the increase in remote work, the demand for lenses and films that cut blue light has been rising. However, since the blue light region also affects the visible light spectrum, it impacts the coloring of the final products. The products in question do not have absorption capabilities in the transmission range above 400nm, which affects the visible light spectrum, allowing for low coloring and molding of the products. Compared to the company's products "DAINSORB T-7" and "DAINSORB T-52," the solvents used are different, so by selecting materials according to the solvent currently in use, it is possible to design coatings that incorporate blue light cutting performance without significantly changing the current formulation. Additionally, they have good compatibility with toluene and xylene, making them suitable for paint applications as well.

"VERZONE Oil MS-6" is an anti-rust oil developed for the protection of cylinder rolls during storage and transportation. It has been used by many customers, enabling long-term use of cylinder rolls! During long-term storage of cylinder rolls, cracks may occur in the chrome plating on the surface of the cylinder rolls, which is multi-layered, leading to corrosion of the underlying metal. By applying this product to the surface of the cylinder rolls, the anti-rust agent penetrates the cracked areas and prevents corrosion of the underlying metal. It also prevents chrome roughening. The anti-rust oil film is extremely thin at the molecular level, yet it remains intact and is easy to remove. It can be used with standard application methods such as brushing, dipping, or spraying.

The rust inhibitor vaporizes and protects the surface of the metal from rust. It is a very easy rust prevention method, as you only need to place the vapor-phase rust inhibitor together with the metal products! Complete sealing is not necessary; a certain level of sealing is sufficient. ■ How to use the vapor-phase rust inhibitor Simply seal the metal parts you want to protect from rust together with the vapor-phase rust inhibitor. (For example, put them in a box or cover them with a bag) ■ Mechanism of the vapor-phase rust inhibitor 1. The rust inhibitor vaporizes. 2. The rust inhibitor fills the sealed space (inside the box or packaging). 3. The vaporized rust inhibitor protects the surface of the metal. ■ Other features - No need for coating or cleaning. - The gas from the rust inhibitor reaches even complexly shaped metal parts. - Even if it gets wet due to condensation, the vapor-phase rust inhibitor dissolves in water and suppresses rust.

When plating silver onto a resist pattern substrate, conventional cyan baths make it impossible to form a plating film according to the pattern due to the dissolution of the resist. With the acidic "Dine Silver GPE" series, plating can be done according to the pattern without damaging the resist, and it is being adopted for silver plating on resist pattern substrates. ■ Direct plating onto the resist pattern is possible, eliminating the need for special mask processing and allowing for process shortening. ■ A wide range of options from matte to glossy is available to suit various applications. *For details, please refer to the related links below and the PDF materials.
