Description
A class of Antioxidant added to varnishes and polymers to minimize photochemical degradation. Hindered amine light stabilizers (HALS) act as a catalyst to deactivate the peroxy radicals. Thus, they are effective without being consumed. Many HALS additives are derivatives of 2,2,6,6-tetramethylpiperidine. (Mills and White 1994).
