RIASORB UV-928 is a new type of benzotriazole-based ultraviolet absorber developed specifically for high-performance paint applications. It has a relatively wide absorption wavelength range, effectively protecting coatings and materials. Additionally, it possesses high solubility, compatibility, heat resistance, and durability, making it suitable for high-temperature processing such as powder coatings and coil coatings. RIASORB UV-928 demonstrates a synergistic effect when used in combination with hindered amine-based light stabilizers, contributing to the prevention of color change, maintenance of gloss, prevention of cracks and bubbles, and prevention of interlayer peeling in paints. In Japan, UV 384-2 and UV-1130 are often used for paint applications. As Ryanglon Japan, we recommend UV-928 for paint applications due to its superior absorption efficiency compared to the two products mentioned above. Furthermore, UV-928 is a powder product (non-hazardous according to fire laws), so it does not require a hazardous materials storage facility like UV-1130 and UV 384-2. We can also provide data on ultraviolet absorption wavelengths and other information, so please feel free to contact us.
Low volatility benzotriazole ultraviolet absorbers

It is ideal for sun care and skin care products aimed at everyday protection.
Dispersion and stabilization in water or solvents is possible! Since functional groups are not added, the performance of the basic framework is maintained.
This document introduces the ultraviolet absorbers "zinc oxide dispersion" and "benzoxazine dispersion." It includes information on the "physical properties," "transmittance," "absorbance," and "weather resistance" of zinc oxide and benzoxazine dispersions. By micronizing the ultraviolet absorber particles and using them as cut particles at a wavelength of 380nm, high weather resistance can also be achieved. Please take a moment to read it.

High solubility, ultraviolet absorber "DAINSORB P-7"
Recently, not only plastic products but also adhesives used in films, substrates, etc., have been utilizing UV absorbers for substrate protection. This product is a type of UV absorber that improves solubility in non-polar solvents while also being soluble in general-purpose solvents, allowing for a wider range of applications compared to the similar product "DAINSORB P-6."
Blue light cut, low-color ultraviolet absorber "DAINSORB T-53"
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.
