Description

2,9,11,13,15,22,24,26,27,28-Decaazatricyclo21.3.1.110,14octacosa-1(27),10,12,14(28),23,25-hexaene-12,25-diamine, N,N-bis(1,1,3,3-tetramethylbutyl)-2,9,15,22-tetrakis(2,2,6,6-tetramethyl-4-piperidinyl)- is a high-performance hindered amine light stabilizer (HALS) designed for superior polymer protection. This compound is critical for extending the service life and maintaining the aesthetic and mechanical properties of plastics exposed to harsh environmental conditions. It is an essential additive for manufacturers in the automotive, construction, and packaging industries seeking to enhance product durability against UV degradation and thermal oxidation.

Application

• Polymer Stabilization: Primary use as a highly effective light and heat stabilizer in polyolefins (PP, PE), engineering plastics, and synthetic fibers.
• Automotive Components: Protection of interior and exterior plastic parts, including bumpers, dashboards, trims, and under-the-hood components from UV-induced fading and embrittlement.
• Agricultural Films & Geotextiles: Extending the functional lifespan of greenhouse films, mulch films, and soil stabilization fabrics exposed to continuous sunlight.
• Construction Materials: Stabilization of PVC profiles, siding, roofing membranes, and other building materials to prevent color change and loss of mechanical strength.
• Industrial Coatings & Paints: Enhancing the weatherability and gloss retention of industrial and automotive coatings.
• Advanced Packaging: Used in films and containers requiring long-term stability against light exposure during storage and use.
