UV Absorber

UV-1 Cas 57834-33-0

UV absorber UV-1 (101) is a liquid phenyl imidazole type UV absorber that can effectively absorb 280 to 350 nanometers of UV light, with a peak absorption of 308 nanometers. Almost all ultraviolet light at 300-330 nanometers is absorbed.

It has the characteristics of good compatibility, low volatility, good thermal stability, and high absorption efficiency, and is easily soluble in polyester polyols, polyether polyols, epoxy resins, and isocyanates. Suitable for adhesives, potting adhesives, crystal drop adhesives, especially for polyurethane, hard foam, soft foam, adhesives, elastomers, fabric coatings, polyvinyl chloride, acrylic resins. The general dosage is 0.3-0.5%.
