To improve the durability of materials under prolonged sunlight and outdoor exposure, UFC offers Hindered Amine Light Stabilizers (HALS) as essential additives for protection against photo-aging. HALS work by efficiently scavenging free radicals, preventing the photo-degradation of polymers caused by UV radiation, and significantly extending product lifespan and appearance retention.
Unlike traditional UV absorbers, HALS provide long-lasting stabilization and create a self-regenerating protective cycle within the material.
This unique mechanism continuously suppresses UV-induced deterioration, making HALS particularly suitable for outdoor plastics, automotive parts, coatings, and agricultural films.
