Molecular Weight

508.8/ 369.5

Specifications

Appreance

Colorless to light yellowish liquid

Purity

≥96(GC)

Freezing point

≤-10 ^oC

Ash

≤0.1%

Transmittance

425 nm≥98%   500 nm≥99%

Advantage and Application

1. As liquid hindered amine light stabilizer, UV-292 can improve the durability of clear coats by inhibiting or retarding the occurrence of failures such as gloss reduction, cracking, color change, blistering and delamination.
2. It has cooperative effects with UV absorbers of benzotriazol.
3.  It is mainly used in polyolefin, unsaturated polyester, PMMA, etc., especially suitable for polyurethane. It effects better on car special coatings because of good solubility in the solvent.
