Description

Butanedioic acid, bis[2-[[4,6-bis[(3-methoxypropyl)(2,2,6,6-tetramethyl-4-piperidinyl)amino]-1,3,5-triazin-2-yl][2-[[4,6-bis[(3-methoxypropyl)(2,2,6,6-tetramethyl-4-piperidinyl)amino]-1,3,5-triazin-2-yl]amino]ethyl]amino]ethyl] ester is a high-performance, polymeric hindered amine light stabilizer (HALS) designed for superior long-term protection against UV degradation. This compound is critical for extending the service life and maintaining the mechanical properties of polymers exposed to harsh environmental conditions. It is an essential additive for manufacturers in the plastics, coatings, and synthetic fiber industries seeking to enhance product durability and performance.

Application

• Polymer Stabilization: Primary use as a high-efficiency light stabilizer in polyolefins (PP, PE), engineering plastics, and thermoplastic elastomers to prevent photo-oxidation and embrittlement.
• Automotive Components: Protection of interior and exterior plastic parts, such as bumpers, dashboards, and trim, from UV-induced color fading and loss of mechanical strength.
• Industrial and Agricultural Films: Extending the functional lifespan of greenhouse films, mulch films, and geomembranes exposed to continuous sunlight.
• Protective Coatings and Paints: Formulation additive for automotive, industrial, and architectural coatings to prevent chalking, gloss loss, and cracking.
• Synthetic Fibers and Textiles: Stabilization of polypropylene and nylon fibers used in outdoor fabrics, carpets, and geotextiles against UV degradation.
• Wire and Cable Insulation: Enhancing the long-term thermal and UV stability of insulation and jacketing materials for outdoor applications.
