Description

N,N'-dibutyl-N-[4-[butyl(2,2,6,6-tetramethyl-4-piperidyl)amino]-6-chloro-1,3,5-triazin-2-yl]-6-chloro-N'-(2,2,6,6-tetramethyl-4-piperidyl)-1,3,5-triazine-2,4-diamine is a high-performance, sterically hindered amine light stabilizer (HALS) designed for superior polymer protection. This compound is critical for extending the service life of plastics and coatings by effectively scavenging free radicals generated during photo-oxidative degradation. It is an essential additive for manufacturers in the plastics, automotive, and construction industries seeking to enhance the durability and color stability of their products under demanding environmental conditions.

Application

• Primary use as a highly effective light stabilizer (HALS) in polyolefin plastics such as polypropylene (PP) and polyethylene (PE).
• Critical additive in automotive exterior parts (bumpers, trim, panels) to prevent cracking, chalking, and gloss loss from UV exposure.
• Enhances weatherability in construction materials including geomembranes, pipes, siding, and roofing films.
• Protects industrial and agricultural films from premature embrittlement and failure due to sunlight.
• Used in fiber and yarn applications to maintain tensile strength and color fidelity.
• Formulation component for high-performance coatings and paints requiring long-term outdoor durability.
• Stabilizer for engineering plastics and polymer blends used in demanding environments.
