BLS® 1328
BLS® 1328 is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers. BLS® 1328 protects polymers as well as organic pigments from UV radiation helping to preserve the original appearance and physical integrity of molded articles, films, sheets, and fibers during outdoor weathering.
Applications: High solubility and superior properties make BLS® 1328 particularly suitable for light stabilizing in coatings, propylene, polyurethane and polyvinyl chloride. BLS® 1328 is also efficient for the light stabilization of unsaturated polyester, polyacrylate, polycarbonate, rigid and flexible polyvinyl chloride, ABS, epoxy, acrylic, and polystyrene. BLS® 1328 features strong UV absorption, low color contribution, and moderately low volatility which makes it highly recommended for protective coatings and a variety of automotive coating substrates like two component polyurethanes and thermoset acrylic enamels. BLS® 1328 has excellent solubility in urethane solvents, is non-reactive and has no effect on the cured properties of the coating while protecting against loss of gloss. In thermoset acrylic enamels the low volatility and high solubility of BLS® 1328 make it especially attractive in thermosetting acrylic finishes. BLS® 1328 protects against loss of gloss and is useful in thermosetting acrylic clear topcoats where it protects against interfacial adhesive loss between the topcoat and the base coat. BLS® 1328 is generally superior to other ultraviolet light absorbers in terms of retaining color after light exposure, especially when used in combination with BNX® 1010. BLS® 1328 can also be used in combination with hindered amine light stabilizers to provide enhanced performance.
