Tinuvin® 5151

Tinuvin® 5151 by BASF is a liquid blend of a hydrophilic 2-(2-hydroxyphenyl)-benzotriazole UV absorber (UVA) and a basic hindered amine light stabilizer (HALS) designed to fulfill high cost/performance and durability requirements of exterior water- and solvent-borne industrial and decorative coatings. It is a hydroxy-functional UVA that can be reacted with isocyanate and melamine crosslinkers to minimize migration. It exhibits excellent spectral coverage in the UV region. Its use is especially recommended for clear and light pigmented systems like thermoplastics (acrylics, vinylic), 1- and 2 K-PUR (acrylic/NCO, PES/NCO) and water-borne systems (acrylic, PUD, 2K-PUR). Tinuvin® 5151 is used in wood stains and varnishes, wood care products, waxes, architectural (roof tiles, walls, floor coatings)-, glass and ceramic (architectural glazing, packaging)-, refinish-, exterior construction-, heavy-duty maintenance- and marine coatings. It is also 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, color change and provides full substrate protection.
