General
TINUVIN® 292 is a liquid hindered amine light stabilizer especially developed for coatings. It is an almost pure mixture of the two active ingredients below. It is this combination that keeps the product liquid, unlike the pure diester which tends to solidify, even at room temperature. The efficiency of TINUVIN® 292 provides significantly extended lifetime to coatings by minimizing paint defects such as cracking and loss of gloss. The dispersion of TINUVIN® 292 in waterborne coatings may be facilitated by dilution with a water-miscible solvent such as butylcarbitol. The performance of TINUVIN® 292 can be significantly improved when used in combination with a UV absorber such as recommended below. These synergistic combinations give coatings superior protection against gloss reduction, cracking, blistering, delamination and color change.
