Wax Additive
CAS Number: 8002-74-2
Micronized polyethylene wax additive used to improve surface properties, scratch resistance, and slip in coatings, inks, and plastics. The fine particle size ensures uniform distribution throughout the film, imparting a smooth, silky surface feel. It also acts as a matting agent and improves blocking resistance in overprint varnishes.
