Tinuvin® 213

Technical DataSheet | Supplied by BASF

Tinuvin® 213 by BASF is reaction products of methyl 3-(3-(2H-benzotriazole-2-yl)-5-t-butyl-4-hydroxyphenyl) propionate/ PEG 300. It acts as a UV absorber belonging to hydroxyphenyl benzotriazole class which imparts good light stability to a variety of polymers. It is a pumpable liquid useful in a variety of substrates and applications, including polyurethanes, liquid color concentrates, elastomers, styrene homo- and copolymers, PMMA, vinyl polymers (PVB, PVC), engineering plastics (e.g. polycarbonate), polyesters and polyolefins. Provides excellent UV absorption to protect polymers from photodegradation. Offers ease of handling and incorporation. It is less volatile than many alternative UVAs, thus providing greater permanence during processing or heat aging conditions. Suitable for adhesives and sealants. Use levels range from 0.15 % to 1.0 %, depending on the substrate and performance requirements of the final application. Tinuvin® 213 by BASF can be used alone or in a combination with other functional additives such as antioxidants (hindered phenols, phosphites) and HALS light stabilizers.
