GW-628 is a new-structure reactive hindered amine light stabilizer. Furthermore, GW-628 shows good UV-absorbing Property due to unsaturated bond present. GW-628 is a typical representative of high-powered light stabilizers, which has excellent cooperation with many UV absorbers, HALS, antioxidants.

Application & Features:

GW-628 is a hindered amine light stabilizer containing reactive group which can react with and graftonto the polymer molecule while exposed to UV-ray. Once the graft happens, the ever-lasting layer of light stabilizer is formed, thus it can provide persistent protection against light degradation.
GW-628 can be used in industrial coatings, paints, adhesives, and plastics (e.g. PP, PE, PS, PVC, ABS, PET, EPDM, etc.) The recommended level of GW-628 is 0.3%.
