Description

Bis-(1-Octyloxy-2,2,6,6-Tetramethylpiperidinyl)-Sebacate is a high-performance hindered amine light stabilizer (HALS) belonging to the NOR-HALS subclass. This compound is critical for providing exceptional long-term thermal and light stabilization to polymers, preventing degradation and extending the service life of finished products. It is an essential additive for manufacturers in the plastics, coatings, and synthetic fiber industries who require superior protection against UV radiation and oxidative stress for their high-value materials.

Application

• Polyolefin Stabilization: Primary light and thermal stabilizer for polypropylene (PP) and polyethylene (PE) films, fibers, and molded articles.
• Engineering Plastics: Used to protect polymers like polyamides (PA), polyacetals (POM), and thermoplastic polyurethanes (TPU) from photo-oxidation.
• Automotive & Industrial Coatings: Imparts excellent weatherability and gloss retention to automotive clearcoats, industrial paints, and powder coatings.
• Adhesives & Sealants: Enhances the durability and prevents chalking or cracking in adhesive films and sealant formulations exposed to sunlight.
• Agricultural Films: Extends the functional lifespan of greenhouse films, mulch films, and silage covers by mitigating UV-induced embrittlement.
• Synthetic Fibers: Protects polyolefin and polyamide fibers used in outdoor textiles, geotextiles, and artificial turf from color fading and strength loss.
