Description

1,2,3,4-Butanetetracarboxylic acid polymer with 2,2-bis(hydroxymethyl)-1,3-propanediol and 3-hydroxy-2,2-dimethylpropanal, 2,2,6,6-tetramethyl-4-piperidinyl ester is a high-performance polymeric hindered amine light stabilizer (HALS) designed for superior long-term protection of polymers against photo-oxidative degradation. This advanced additive is critical for manufacturers requiring enhanced weatherability and extended service life for their plastic and coating formulations under demanding environmental conditions. It is essential for industries producing automotive components, construction materials, and high-durability industrial coatings where color retention and mechanical integrity are paramount.

Application

• As a primary light stabilizer in polyolefin films, fibers, and molded articles for outdoor applications.
• Enhancing the UV resistance and longevity of automotive exterior parts, including bumpers, trims, and under-the-hood components.
• Protecting industrial and architectural coatings, such as powder coatings and coil coatings, from chalking and gloss loss.
• Stabilizing engineering plastics like polyamides (PA) and thermoplastic polyolefins (TPO) used in demanding environments.
• Improving the weatherability of agricultural films and greenhouse covers to extend their functional lifespan.
• Used in masterbatch production for easy and uniform dispersion of stabilizer properties in various polymer matrices.
• Providing synergistic stabilization effects when combined with other additives like UV absorbers and antioxidants.
