SINOLSTAB® UV-292 is a low molecular weight hindered amine light stabilizer that is soluble in most common organic solvents and has better compatibility with many polymers. It has a synergistic effect with UV absorbers. It can effectively prevent the coating from cracking and surface peeling under sunlight exposure. It is more effective in automotive special coatings and has a good synergistic effect with benzotriazole UV absorbers.

SINOLSTAB® UV-292(HS-508) is a highly effective hindered amine light stabilizer (HALS). It is a liquid hindered amine light stabilizer that exhibits excellent light stability in applications such as coatings, printing inks and polyurethane paints to prevent surface popping or flaking. It is widely used for light stabilization of polypropylene, polyethylene, styrene, unsaturated polyesters, acrylic resins, vinyl polymers (PVC, PVB) including plastisols, elastomers, adhesives, sealants and coatings. It is often recommended for polyurethanes due to its solubility in polyols. SINOLSTAB® UV-292 generally has reduced interactions with co-additives such as pigments or other stabilizers. SINOLSTAB® UV-292 has strong synergy with UV absorbers from the benzotriazole family, especially when used in coatings for automotive and wooden furniture.
