TINUVIN® 328
TINUVIN 328 is a UV absorber of the hydroxyphenyl-benzotriazole class designed for coatings. Because of its extended UV absorption, TINUVIN 328 provides efficient protection to coatings and light sensitive substrates. This slightly yellow powder may be used in combination with a light stabilizer of the sterically hindered amine or aminoether class (HALS) such as recommended below. These combinations give coatings superior protection against gloss reduction, cracking, blistering, delamination and color change. TINUVIN 328 is only recommended for ambient and low temperature cured systems, i.e. air-drying alkyd-based systems.
