As an important additive, micronized wax has an irreplaceable role in the field of ink coatings. It can significantly improve the surface properties of ink coatings, enhance scratch resistance, abrasion resistance, anti-adhesion, as well as improve the feel and control the gloss. In addition, the micronized wax can prevent pigment settling and cooperate with matte powder to produce matte paint.
There is a wide range of micronized waxes, mainly including Fischer-Tropsch waxes, polyethylene waxes, polypropylene waxes, polytetrafluoroethylene waxes and modified micronized waxes. Among them, Fischer-Tropsch wax is a kind of unbranched linear wax with low melting point and excellent smoothness and dispersibility; polyethylene wax has excellent anti-friction, anti-scratch, anti-adhesion and light retention; polypropylene wax has higher softening point and hardness, and has outstanding anti-adhesion and abrasion resistance; polytetrafluoroethylene wax has a high melting point, high density, and has excellent comprehensive performance, but is difficult to be dispersed and has a higher price; and modified micronized wax combines many advantages by modifying other waxes through a specific process. Modified micronized waxes combine the advantages of other waxes through a specific process.
