Polyethylene Wax (Micronized)
CAS Number: 9002-88-4
Micronized high-density polyethylene wax with a narrow particle size distribution, engineered for use in solvent-based and UV-curable printing inks. It migrates to the surface of the dried ink film to form a protective layer that significantly improves rub, scratch, and abrasion resistance. The fine particle size ensures excellent gloss retention and print film clarity.
