Introduction
|
Sunvin 51 is a liquid benzotriazole type UV
absorber, which imparts excellent light stability to the various polymers.
Sunvin 51 can be used for PS type polymers,
elastomers, adhesives, rigid and plasticized PVC, thermoplastic PUR, PVB, EVA, PA,
TPE, hot cured unsaturated polyesters.
Sunvin 51 can be applied for combination with
other additives, such as phenolic antioxidant ( Sunox 1135 etc.), HALS UV
absorber (Horsorb 292 etc.).
