With appearance of white or pale yellow crystalline powder, it is soluble in organic solvents including benzene, chloroform, methyl alcohol, alcohol and diethyl ether etc.; insoluble in water. Improving heat resistance while working with antioxidants. Display synergistic effect when working with ultraviolet absorber and improve on light stability. 52829-07-9 light stabilizer UV 770 is a low molecular hals, has good compatibility with most polymers and has synergistic effects with antioxidants and UV absorbers.

52829-07-9 Light Stabilizer HALS UV 770 is a light stabilizer belonging to the class of hindered amine light stabilizers. It provides outstanding light stability to many polymers and, in addition, gives long-term heat stability to polymers by a radical trapping mechanism similar to that of hinder phenol. Its effectiveness can be greatly enhanced by co-addition of other UV absorbers or nickel-containing stabilizers. This product is a white crystalline powder or white granule.
