GOYENCHEMUV-3638 CAS NO. 18600-59-4
GOYENCHEMUV-3638 is a highly-effective UV absorber based on the structure of benzoxazinone that is with high stability and light fastness properties. Thanks to its twice the absorption at UV-A range than triazine or benzotriazole based UV absorbers on the same weight basis, GOYENCHEMUV-3638 is perfectly suitable for engineering plastics and polymers which extra protection at blue-swift UV regions is required.
