Audited Supplier Overview
UV 99-2 is a liquid benzotriazole UV absorber that provides outstanding light stability to industrial and automotive coatings. As a liquid, UV 99-2 blends easily and disperses completely, resulting in lower loading requirements, and virtually eliminating the particle dispersion problems associated with conventional powder UV absorbers. The liquid form also allows for outstanding compatibility with a wide variety of coating systems, including waterborne and solvent-based coatings.

Application:
UV 99-2 is a liquid UV absorber providing excellent protection against ultraviolet degradation in coatings, including automotive and industrial coatings, paints, and wood stains. It is ideal for use in both water- and solvent-based systems. Should the self color of UV 99-2 be an issue, it is recommended to test UV 384-2 as a potential alternative. Combinations of UV 99-2 with hindered amine light stabilizers such as LS 292 or LS 123 often provide significantly enhanced performance, providing maximum long-term protection against blistering, color change, cracking, gloss reduction, and delamination.
Storage and transportation:
This product may be stored up to two years in a sealed container. Containers should be kept tightly closed when not in use and stored in a cool, dry place.
