In coatings, UV exposure is the main cause of aging and failure. Prolonged sunlight leads to yellowing, fading, gloss loss, chalking, cracking, and reduced adhesion—shortening coating life and lowering product quality.

During polymer processing, high temperatures can easily cause thermal oxidative degradation, leading to yellowing and reduced mechanical properties.

In optical films, displays, LED lighting, and protective eyewear, UV and blue light are major causes of yellowing and aging over time.

With smartphones, tablets, vehicle displays, and LED lights everywhere, high-energy short-wave blue light (380–440 nm) is a major cause of eye strain and blurred vision.

Outdoor plastic products face constant aging from UV, heat, and moisture. OMNISTAB® LS3529 and LS3346 are high‑molecular‑weight hindered amine light stabilizers (HALS) that provide effective, long‑term protection for polyolefins and engineering plastics.

The highly reactive -NCO end rapidly undergoes addition reactions with hydroxyl, amino and thiol groups;

OMNISTAB® AN91PQ features a thermal decomposition temperature of around 300℃, far superior to conventional phosphite antioxidants.

Polymeric materials are highly susceptible to thermal degradation, yellowing, and mechanical property deterioration during high-temperature extrusion, high-speed injection molding, and prolonged service exposure.
