Description

1,3,5-Triazine-2,4,6-triamine, N,N'''-1,2-ethanediylbis[N-[3-[[4,6-bis[(3-methoxypropyl)(2,2,6,6-tetramethyl-4-piperidinyl)amino]-1,3,5-triazin-2-yl]amino]propyl]-N',N''-bis(3-methoxypropyl)-N',N''-bis(2,2,6,6-tetramethyl-4-piperidinyl)- is a high-performance, polymeric hindered amine light stabilizer (HALS) designed for superior long-term protection. This compound is critical for preventing polymer degradation caused by UV radiation, heat, and oxidative stress, thereby extending the service life of finished products. It is essential for manufacturers in the plastics, coatings, and specialty polymer industries who require exceptional weatherability and color retention in demanding outdoor applications.

Application

• Automotive Coatings and Plastics: Provides critical UV stabilization for exterior trim, bumpers, and body panels to prevent fading, chalking, and loss of mechanical properties.
• Industrial and Architectural Coatings: Protects coatings on buildings, bridges, and industrial equipment from photodegradation, ensuring long-lasting color and gloss.
• Agricultural Films and Geomembranes: Extends the functional lifespan of polyethylene and polypropylene films exposed to intense sunlight, retaining strength and clarity.
• Engineering Plastics and Compounds: Used in polyolefins (PP, PE), polyamides, and other engineering resins for automotive components, consumer goods, and construction materials.
• Advanced Polymer Stabilization Systems: Often formulated with other additives like antioxidants and UV absorbers for synergistic, high-performance stabilization packages.

Quality Control

Our production of this advanced light stabilizer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Every lot is characterized using advanced analytical techniques including HPLC, GPC (for molecular weight distribution), and NMR to confirm structure and purity. A comprehensive Certificate of Analysis (COA) detailing assay, melting point, color, and specific performance tests is provided with each shipment, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat sources and open flame. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
