Tinuvin® 213

Tinuvin® 213 by BASF acts as a UV absorber belonging to hydroxyphenyl benzotriazole class which imparts good light stability to a variety of polymers. It is a reaction product of methyl 3-(3-(2H-benzotriazole-2-yl)-5-t-butyl-4-hydroxyphenyl) propionate/ PEG 300. 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 with a dosage level of 0.15-1.0 %. Tinuvin® 213 can be used alone or in a combination with other functional additives such as antioxidants (hindered phenols, phosphites) and HALS light stabilizers.
