BTA is bonded to the polymer main chain, giving it long-term ultraviolet absorption capability!
The "high weather-resistant resin" developed by our company incorporates BTA-based ultraviolet absorbers in a high concentration into the resin, thereby improving compatibility with other functional materials, enabling thin film formation during coating, and suppressing the bleeding of ultraviolet absorbers over time. Since BTA is chemically bonded to the resin backbone, high concentration is possible. This allows for sufficient ultraviolet absorption capability even when formed into a thin film, and additionally, it enables a wider range of functional materials to be added, making design changes according to application easier. We can accommodate design changes based on customer requests, so please feel free to contact us when needed. 【Features】 ■ Suppresses thin film formation during coating and bleeding of ultraviolet absorbers over time ■ Possesses long-term ultraviolet absorption capability due to BTA's bonding with the polymer backbone ■ High concentration of BTA is possible ■ Minimal adverse effects on added targets *For more details, please refer to the PDF document or feel free to contact us.

Company information
Toshin Yushi Co., Ltd. is a company engaged in the manufacturing and sales of varnishes for inks and paints. In recent years, we have been responding to various requests not only for conventional products but also for automotive-related, electronic component-related, and building materials-related applications, and we are also focusing on the development of biomass-related products as environmentally friendly options. Additionally, apart from our in-house developed products, we also undertake contract manufacturing of various chemicals. We cater to a wide range of customer needs, from small to large lots, including the condensation of acrylic resins, urethane resins, alkyd resins, polyester resins, epoxy resins, and polyamides. Leveraging our experience and know-how accumulated over more than half a century, we will continue to explore new possibilities as a specialty store for varnishes.
