A light stabilizer belonging to the triazine class of UVAs.


Triazine ultraviolet absorber


RIASORB® UV-460 is a solid triazine UV absorber. Due to its extremely high absorption, it provides outstanding protection to light-sensitive substrates and materials, especially in ultrathin to thin films. RIASORB® UV-460 is recommended for use in optical materials such as photographic papers, optical films. It can be also used in high performance packaging coatings, industrial coatings, wood stains or do-it-yourself paints, and vehicle coatings. In combination with other UV absorbers, RIASORB® UV-460 can match desired absorption characteristics. RIASORB® UV-460 can also be used together with HALS to achieve superior durability.
