CHEMK UV-5060

CHEMK UV-5060 by Jiangsu Chemk is a light stabilizer blend combining a 2-(2-hydroxyphenyl)-benzotriazole UV absorber (UVA) with a non-basic hindered amine light stabilizer (HALS). It is developed to meet high durability and cost/performance requirements in exterior solvent-borne industrial and decorative coatings. The broad UV absorbance makes it suitable for a wide range of coatings for wood, plastics, and metal. The non-basic character of the used N-OR HALS prevents interactions with acidic paint ingredients like catalysts, biocides, and pigments.

• The synergistic combination imparts superior coating protection, full substrate protection and enhances resistance to gloss reduction, cracking, blistering, delamination, and color change.
• Designed for solvent-based systems, wood stains, varnishes, wood care products, waxes, general industrial paints.
• Recommended for heavy-duty maintenance and marine, architectural (roof tiles, walls, floor coatings), glass and ceramic coatings (architectural glazing, packaging).
• It is ideal for clear and light pigmented systems including thermoplastics (acrylics, vinylics), acid-catalyzed paints (acrylic, PES/melamine), and oxidative drying systems (alkyds, oils, waxes).
