Description and Uses

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.

Tinuvin 292 is a multi-purpose liquid alkaline hindered amine light stabilizer for coatings, printing and packaging, adhesives and sealants. It is used to meet high-performance and durable solvent and exterior coating applications, including radiation curable systems (UV, electron beam).
