Propery and applications:
UV-360 is a very low volatile. Dimeric 2-hydroxy benzotriazole UV-absorber used in a variety of polymers
and resin compositions. UV360 is an excellent UV absorber and can be used in polyacrylic resin, polyalkene,
polyamide and in elastoplastic goods with good compatibility and higher UV absorbability. Used with other additive
such as antioxidant, is shows synergistic effect. Yellowish powder, insoluble in water, soluble in esters. And benzoid
solvents, high thermostability.
Package: 25Kg, paperboard packing drum lining plastics bag
