UV Absorber UV-384-2
Liquid hydroxyphenyl-triazine UV absorber
Liquid triazine UVA — the weathering workhorse for high-bake coatings.
Product Description
UV-384-2 is a liquid hydroxyphenyl-triazine (HPT) UV absorber providing strong, broad 300–400 nm coverage. The triazine core brings high thermal and environmental permanence, surviving the high bake schedules of automotive and industrial paints without yellowing or migration.
The liquid form of UV-384-2 pumps and meters easily, is fully compatible with common coating solvents and resin systems, and disperses readily in clears and pigmented paints. Films keep gloss and color superbly under long-term outdoor exposure — a first-line UVA for severe-duty coatings.
Typical addition is 1–3% on resin solids, recommended with HALS such as UV-292 or UV-123. Aolong UV-384-2 ships with consistent batches and full regulatory documentation.
