UV Absorber UV BP-6 CAS 131-54-4

UV Absorber UV BP-6 is a benzophenone-based ultraviolet light stabilizer. It appears as a fine, pale yellow to light yellow crystalline powder with a faint characteristic odor. Practically insoluble in water, but soluble in organic solvents such as ethanol, acetone, ethyl acetate, and toluene. Commonly used in plastic and polymer industries to protect materials (such as polyvinyl chloride, polyolefins, polystyrenics, and acrylic resins) from UV-induced degradation, yellowing, and loss of mechanical properties. Also functions as a light stabilizer in coatings, paints, adhesives, and sealants to improve outdoor weatherability and durability. Stable under normal storage conditions and should be kept in tightly sealed containers away from light, moisture, and strong oxidizing agents.
