YILIGHT® 765 is a liquid hindered amine type light stabilizer. The product features low volatility and good compatibility, and can effectively prevent cracking on the surface of polymer materials and loss of luster, thereby extending the service life. It is suitable for single-layer or double-layer polyurethane, thermoplastic acrylic, thermosetting acrylic, water-based acrylic, alkyd, polyester, polyurethane foaming and other materials.
It is recommended to use YILIGHT® 765 in combination with ultraviolet absorbers such as YISORB® UV-1 or YISORB® UV-1130, which will significantly improve the weather resistance of the product.
