UV-312 is an oxalanilide series UV absorber that is effective in a variety of polymers and applications. Applications in plastics include polyamide, PVC (rigid and flexible), polyester (thermoplastic and thermoset), polyurethane, adhesives and seals. The product is also suitable for powder coatings, solvent-based coatings, used in automotive paints, industrial paints and architectural paints.
Depending on the application, the typical addition level of UV-312 is between 0.1-1%. This product has a good synergistic effect with hindered amine series light stabilizers and benzoate UV absorbers. In the coating industry, the general addition amount is 0.5%-3.5% of UV-312 and 0.5-2% of hindered amine series light stabilizer, and the addition amount is based on the weight percentage of resin solids. Appropriate testing must be used to determine the appropriate level of addition for a particular application.
