Use
UV5151 is a liquid blend of a hydrophilic 2-(2-hydroxyphenyl)-benzotriazole UV absorber (UVA) and a basic hindered amine light stabilizer(HALS).It has been designed to fulfil high cost/performance and durability requirements of exterior waterborne and solvent borne industrial and decorative coatings. The broad UV absorbance of the used UVA makes it suitable for a wide range of coatings for wood, plastics and metal. The synergistic combination imparts superior coating protection against gloss reduction, cracking, blistering, delamination and color change and provides full substrate protection.
