Description

Bis-(1-Octyloxy-2,2,6,6-Tetramethyl-4-Piperidinyl) Sebacate is a high-performance hindered amine light stabilizer (HALS) belonging to the NOR-HALS subclass. This compound is critical for protecting polymers from the damaging effects of UV radiation and thermal degradation, thereby significantly extending the service life of finished products. It is an essential additive for manufacturers in the plastics, coatings, and synthetic fiber industries who require long-term durability and color retention for their materials exposed to outdoor environments.

Application

• Polyolefin Stabilization: Primary light stabilizer for polypropylene (PP) and polyethylene (PE) films, fibers, and molded articles, providing exceptional long-term thermal stability (LTS).
• Engineering Plastics: Used in styrenics (PS, ABS, HIPS) and other engineering polymers to prevent yellowing and maintain mechanical properties.
• Automotive & Industrial Coatings: Imparts superior gloss retention and prevents cracking and chalking in automotive clearcoats, industrial paints, and powder coatings.
• Adhesives & Sealants: Enhances the weatherability and lifespan of polyurethane and other polymer-based adhesive formulations.
• Agricultural Films: Protects greenhouse and mulch films from solar UV degradation, ensuring multi-season performance.
• Synthetic Fibers: Stabilizes polypropylene and polyethylene fibers used in outdoor textiles, geotextiles, and artificial turf.
