Light Stabilizers Selection Guide
Outdoor plastics and coatings fail by UV absorption or by radical degradation at the surface. The right stabilizer depends on substrate thickness, exposure, and whether the part is thick-section or a thin film.
Your exposure scenarioStabilizer strategyNotes
Thick-section parts (auto trim, outdoor furniture)HALS primary, optionally UV absorberHALS regenerate; low surface-area loss
Thin films & fibers (ag film, tapes)UV absorber + HALS combinationSurface area high; absorber needed to block bulk UV
Clear coatings over sensitive substratesUV absorber (liquid/transparent) + HALSAbsorber protects substrate; HALS protects film
Pigmented systems, harsh climatesHigh-molecular-weight HALSLower migration; longer-term durability
