Description

Hexahydro-1,3,5-Tris(2,2,6,6-Tetramethyl-4-Piperidyl)-1,3,5-Triazine is a high-performance, sterically hindered amine light stabilizer (HALS) of the triazine class. This compound is critical for protecting polymers and coatings from the degrading effects of UV radiation and thermal oxidation, thereby significantly extending product service life. It is an essential additive for manufacturers in the plastics, automotive, and construction materials industries seeking to enhance the durability and weatherability of their products.

Application

• Polyolefin Stabilization: Primary light and heat stabilizer for polypropylene (PP) and polyethylene (PE) fibers, films, and molded articles.
• Automotive Plastics & Coatings: Protects interior and exterior plastic components, as well as automotive clearcoats, from UV-induced yellowing and cracking.
• Engineering Plastics: Enhances the long-term thermal stability and color retention of polymers like ABS, polyamide (PA), and polycarbonate (PC) blends.
• Industrial & Architectural Coatings: Used in high-performance industrial coatings, powder coatings, and wood finishes to prevent gloss loss and chalking.
• Agricultural Films: Extends the functional lifespan of greenhouse and mulch films exposed to intense sunlight.
• Adhesives & Sealants: Improves the durability of polyurethane and other polymer-based adhesives used in outdoor applications.
• Synthetic Fibers: Stabilizes polypropylene and polyethylene terephthalate (PET) fibers against photodegradation.
