UV Absorber BP-6

Product Overview

UV Absorber BP-6, chemically known as a benzophenone derivative, stands as a premier solution in the realm of light stabilization for diverse polymeric materials. This high-performance additive is engineered to effectively absorb harmful ultraviolet radiation within the critical 270 to 400 nanometer range. By dissipating this energy as harmless heat, it significantly mitigates the photo-oxidative degradation that typically leads to cracking, chalking, and loss of mechanical integrity in exposed materials. Our grade is synthesized under strict quality control protocols to ensure consistent batch-to-batch reliability, making it an ideal choice for manufacturers demanding superior durability in their end products.

Key Technical Advantages

The formulation of UV Absorber BP-6 offers a unique balance of physical and chemical properties that distinguish it from conventional stabilizers. Its light yellow powder appearance ensures minimal impact on the aesthetic quality of transparent or lightly pigmented systems. The product exhibits exceptional compatibility with a wide array of resin systems, reducing the risk of blooming or migration over extended service periods. Furthermore, its low volatility ensures that the protective benefits remain intact even under elevated processing temperatures, providing long-term weatherability without compromising the physical properties of the host matrix.

• Excellent UV absorption range covering 270-400nm for broad-spectrum protection
• Superior thermal stability suitable for high-temperature processing operations
• Low volatility and minimal migration to ensure lasting performance
• Non-toxic profile compliant with various industrial safety standards
• Enhances color retention by retarding yellowing in clear coatings

Specifications and Parameters

Industrial Applications

This versatile stabilizer is extensively utilized across multiple sectors including plastics, coatings, and adhesives. In the plastics industry, it is highly effective in polyolefins such as PE, PP, and PVC, as well as engineering plastics like PS and PC. It is particularly valued in the coatings sector for providing robust light stabilization in dry phenolic and alkyd varnishes, polyurethanes, acrylics, and epoxy systems. Automotive refinishing paints benefit significantly from its ability to maintain gloss and color fidelity under harsh sunlight exposure. The recommended dosage typically ranges from 0.1% to 0.5%, depending on the specific substrate and desired level of protection, allowing formulators to optimize cost-performance ratios effectively.

Storage and Handling

UV Absorber BP-6 is classified as non-dangerous goods, facilitating straightforward logistics and transportation. To maintain optimal quality, the product should be stored in a cool, dry, and well-ventilated environment away from direct heat sources and moisture. The packaging consists of cardboard drums lined with plastic bags, ensuring protection against contamination and humidity during storage. Under recommended conditions, the material exhibits excellent storage stability, retaining its specified properties over extended periods. Users are advised to follow standard industrial hygiene practices when handling the powder to prevent unnecessary dust inhalation.
