Linsorb UV 400 Chemical Name: 2-oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine and 2-oxy]-2-hydroxyphenyl]-4,6–bis(2,4- dimethylphenyl)-1,3,5-triazine Formula / Molecular Weight 647 CAS# 153519-44-9 Physical Properties: Appearance Yellow viscous liquid Ash ≤0.1% Density 1.07g/cm3 (20 oC) Purity ≥85%(HPLC) Transmittance 460 nm≥95% 500 nm≥97% Applications: > Features of UV 400 are excellent thermal stability and environmental durability, suitable for coatings used in extremely harsh conditions, low migration, high concentration, and high efficiency, good light stability, and effective long life. Used as tinuvin 400 equivalent. > UV 400 can be used in industrial paints and automotive paints with high performance and durability requirements (water-based, solvent-based, and 100% solids are suitable). UV 400 is a UV absorber that does not cross-react with other components of the system and was developed specifically for amine-catalyzed or metal-catalyzed coating systems. > The use of UV-400 in combination with hindered amine light stabilizers, such as HALS-292 or HALS-123, can significantly increase their effectiveness. This synergistic effect can reduce the gloss of the varnish, resulting in cracks, bubbles, delamination, and discoloration. Good inhibition. Handling and safety: >For additional handling and toxicological information, please consult us for Maternal Safety Date Sheet. Package: 20KG plastic drum Linsorb 400 TDS Linsorb 400 tds
