Description

1,3-Propanediamine, N,N-1,2-ethanediylbis-, reaction products with cyclohexane and peroxidized N-butyl-2,2,6,6-tetramethyl-4-piperidinamine-2,4,6-trichloro-1,3,5-triazine reaction products is a specialized polymeric hindered amine light stabilizer (HALS) designed for superior long-term protection of polymers against photo-oxidative degradation. This high-performance additive is critical for extending the service life and maintaining the aesthetic and mechanical properties of plastics exposed to harsh environmental conditions. It is primarily needed by manufacturers in the polymer and plastics industries for demanding applications requiring exceptional weatherability.

Application

• As a high-efficiency light stabilizer (HALS) in polyolefin films, fibers, and molded articles.
• For the UV protection of automotive components, including bumpers, trims, and under-the-hood parts.
• Enhancing the weatherability and color retention of agricultural films, geomembranes, and outdoor construction materials.
• Stabilization of engineering plastics such as polyamides and polyesters used in electrical and consumer goods.
• Protection of coatings and paints from chalking, gloss loss, and cracking induced by sunlight.
• Use in masterbatch formulations for consistent and easy dispersion of stabilizer properties in polymer matrices.
