Hindered amine light stabilizers (HALS) are one of two methods of combating UV degradation in polymers. HALS are activated during light exposure by scavenging free radicals created by photooxidation. HALS additives protect the bulk and surface of the polymer depending on the thickness.

UV-292 is a liquid Hindered Amine Light Stabilizer (HALS) especially developed for color sensitive coatings applications. It is a very pure mixture of the two active ingredients below. It is this combination that keeps the product liquid, unlike the pure diester which tends to solidify, even at room temperature.
