Product Technical Details

Product Overview

Light Stabilizer 66, chemically known as N1,N3-Bis(2,2,6,6-tetramethylpiperidin-4-yl)isophthalamide, represents a advanced class of hindered amine light stabilizers (HALS) engineered for demanding polymer applications. With the CAS registry number 42774-15-2, this specialty chemical is specifically optimized to enhance the durability and longevity of polyamide materials. Our manufacturing process ensures exceptional purity levels, making it an ideal choice for manufacturers seeking reliable performance in high-stress environments.

As a leading global manufacturer, we understand the critical role additives play in material science. Light Stabilizer 66 functions by scavenging free radicals generated during UV exposure and thermal processing, thereby preventing polymer degradation. This mechanism significantly extends the service life of finished products, maintaining mechanical integrity and aesthetic appearance over time.

Industrial Applications

The primary application domain for Light Stabilizer 66 lies within the polyamide industry, where it serves as a multi-functional additive. Its compatibility with polyamide resins is excellent, ensuring uniform dispersion without compromising the base material's properties. Key benefits observed in industrial settings include:

  • Enhanced melt processing stability, significantly reducing filament breakage during spinning operations.
  • Superior long-term heat and photo-stability, protecting materials from environmental weathering.
  • Synergistic effects when combined with UV absorbers like UV312, providing comprehensive UV protection.
  • Improved light fastness for dyed fibers, enhancing affinity for both pre-metallized and metal-free acid dyes.

These characteristics make it indispensable for textile manufacturing, automotive components, and engineering plastics where exposure to sunlight and heat is inevitable.

Handling And Storage

To maintain optimal quality, Light Stabilizer 66 should be stored in a cool, dry environment away from direct sunlight. Containers must remain tightly closed to prevent moisture absorption and contamination. Our standard packaging consists of 25kg carton boxes, designed for safe global shipping. We provide comprehensive documentation, including Certificates of Analysis (COA), with every shipment to ensure regulatory compliance and quality assurance.
