UV ABSORBER HOSORB UV 312  has a low volatility and good thermal stability. It is particularly effective for short-wavelength UV light. It can be used in solventborne coatings and general industrial coatings to provide standard UV stabilization performances. In particular, it is recommended for UV cured systems. It is suitable for polyesters, PVC plastisol, polyurethanes, polyamides, polymethylmethacrylate, polybutyleneterephtalate, polycarbonates and cellulose esters.  It is particularly effective include polyamides, PVC (rigid and flexible), polyesters (thermoplastic and thermoset). info at hhochem. com
