Hindered amine light stabilizer (HALS) of N-H type that protects polymers from degradation due to ultraviolet radiation and long term heat aging.

Used In

  • Effective for use in PP, PE, ethylene-propylene copolymer and terpolymer, polyurethane, ABS, PS, HIPS, SAN and PVC.
  • Can be used in combination with phenolic and phosphite antioxidants, higher molecular weight HALS, and UVA’s to optimize performance in outdoor use.
  • Use with sulfur-containing additives such as DSTDP or DLDTP can have negative influence.
