UV Absorber 1130

Product Overview

UV Absorber 1130 represents an advanced class of liquid ultraviolet stabilizers specifically engineered for high-performance coating systems. Chemically classified as a hydroxyphenyl benzotriazole derivative complexed with polyethylene glycol esters, this product offers superior protection against photodegradation caused by prolonged exposure to sunlight and artificial UV sources. Unlike solid counterparts, the liquid formulation of UV Absorber 1130 ensures seamless integration into various solvent-based and waterborne matrices, providing manufacturers with enhanced dosing accuracy and homogeneity. The unique molecular structure facilitates efficient energy dissipation through keto-enol tautomerism, converting harmful UV radiation into harmless thermal energy, thereby preserving the integrity and aesthetic appeal of the underlying substrate.

Key Features and Benefits

• Exceptional compatibility with common organic solvents and ease of incorporation into waterborne systems via co-solvents such as butyl carbitol.
• Broad-spectrum UV absorption capabilities ensuring comprehensive protection across critical wavelengths without affecting initial color.
• High thermal stability suitable for demanding industrial curing processes and extreme environmental conditions.
• Synergistic performance when combined with hindered amine light stabilizers (HALS) for maximized durability and service life.
• Low volatility profile minimizes loss during processing and extends the longevity of the final coating application.

Technical Specifications

Industrial Applications

This specialized UV absorber is predominantly engineered for the automotive and industrial coatings sectors, where long-term weatherability is paramount. In automotive finishes, UV Absorber 1130 plays a critical role in preventing gloss reduction, micro-cracking, blistering, and delamination. It effectively mitigates color shift and chalking, ensuring that vehicles maintain their showroom quality over extended periods. When formulated alongside hindered amine light stabilizers such as LS 292 or LS 123, it creates a robust defense system against oxidative degradation. Furthermore, its versatility extends to industrial maintenance coatings, wood finishes, and plastic substrates requiring transparent UV protection without compromising clarity. The liquid nature allows for precise metering in automated production lines, reducing waste and ensuring batch-to-batch consistency across polyurethane, acrylic, and epoxy resin systems.

Handling and Storage

To maintain optimal quality, containers should remain tightly closed in a cool, dry environment away from direct heat sources and moisture. Proper handling procedures ensure safety and product efficacy throughout the supply chain. As a dedicated supplier of functional material additives, we guarantee consistent quality supported by comprehensive Certificates of Analysis (COA) for every shipment. Our commitment to technological innovation ensures that clients receive materials that meet rigorous international standards for performance and safety.
