Light Stabilizers (HALS)
Light Stabilizer UV-292
Bis(1,2,2,6,6-pentamethyl-4-piperidyl) sebacate blend
The liquid HALS designed for coatings — easily incorporated in solvent and waterborne systems.
Product Description
UV-292 is a liquid blend of hindered amine esters engineered specifically for coating systems. Its liquid state allows perfect incorporation into solvent-borne polyurethane, polyester and acrylic coatings as well as waterborne dispersions, where powder stabilizers would be difficult to dissolve.
In automotive refinish and industrial coatings, UV-292 prevents gloss loss, chalking and cracking by inhibiting the photo-oxidative chain reactions that degrade binders. It shows excellent long-term compatibility with minimal haze or precipitation, even in high-solids systems.
Typical use levels are 1–3 wt% on solid resin, often combined with benzotriazole UV absorbers such as UV-329 for a complete UVA + HALS package that protects both the coating and the substrate beneath.
