Light stabilizer additive
WebOne main category of light stabilizers consists of what are known as Hindered Amine Light Stabilizers (abbreviated as HALS). They are derivatives of 2,2,6,6-tetramethylpiperidine and are extremely efficient stabilizers against light-induced degradation of most polymers. WebThe light stabilizer blends combine two main technologies: filters that block ultraviolet radiation and scavengers that “hunt down” and eliminate free radicals within the coating to master a complex array of challenges.
