Material Notes:
GUARD DOGâ„¢ UV292 is a highly effective hindered amine light stabilizer that protects polymers against degradation caused by exposure to UV radiation.Applications: This UV stabilizer is mainly used in Liquid Color Concentrates, Coatings, Printing Ink, Polyolefins, Polyurethane, Sealants, Adhesives, Elastomers, Unsaturated Polyesters, Acrylics and Styrenics. This stabilizer prevents automotive coatings from blowing-out and surface peeling. Also it is found to have a synergistic effect when used in combination with benzotriazole-type UV absorbers.Typical Properties: Product Form - Pale yellow liquid
