Description

2-4,6-Bis(2,4-Dimethylphenyl)-1,3,5-Triazin-2-Yl-5-(Octyloxy)-Phenol CAS NO 195628-73-0 is a high-performance, hindered amine light stabilizer (HALS) belonging to the triazine class of UV absorbers. This compound is specifically engineered to provide exceptional long-term protection for polymers against photo-oxidative degradation caused by ultraviolet (UV) light exposure. It is a critical additive for manufacturers in the plastics, coatings, and synthetic fiber industries who require durable, color-stable products with extended service life in outdoor applications.

Application

This advanced light stabilizer is designed for demanding applications where superior weatherability is non-negotiable. Its primary function is to scavenge free radicals and absorb UV radiation, preventing chain scission and color fading in polymeric materials.

• Automotive Coatings and Plastics: Protects exterior parts, trim, and clearcoats from yellowing and loss of gloss.
• Industrial and Architectural Coatings: Extends the lifespan of protective coatings for buildings, bridges, and industrial equipment exposed to sunlight.
• Engineering Plastics and Polymers: Used in polyolefins (PP, PE), polycarbonate, ABS, and other polymers for outdoor furniture, stadium seats, and construction profiles.
• Agricultural Films and Geotextiles: Enhances the durability of greenhouse films, mulch films, and synthetic fabrics used in harsh environmental conditions.
• Synthetic Fibers and Textiles: Imparts UV resistance to fibers used for outdoor apparel, awnings, tarpaulins, and automotive interiors.
• Adhesives and Sealants: Prevents degradation and maintains elasticity in sealants and adhesives used in exterior applications.

Quality Control

Our production of 2-4,6-Bis(2,4-Dimethylphenyl)-1,3,5-Triazin-2-Yl-5-(Octyloxy)-Phenol adheres to stringent quality management protocols to ensure batch-to-batch consistency and high performance. The material is manufactured and tested in facilities that follow ISO 9001 quality standards. Every lot is analyzed using advanced techniques like HPLC and GC to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee it meets your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, the container should be kept in the original packaging or an opaque container until use.
