Ink is very common in our daily lives, adding a lot of colors to our lives. Whether ink is good for printing has a great impact on the quality of finished products in the later stage.
Wax has been used earlier as a coating and ink additive, characterized by its simple use. After coating application, due to solvent evaporation, wax in the coating precipitates, forming fine crystals that float on the surface of the coating film, playing various roles in improving the performance of the coating film. It can endow the coating film with good water resistance, moisture and heat resistance, scratch resistance, extinction, anti fouling, and good hand feel. Their scratch resistance is beyond that of pigment extinction. pp wax

Polypropylene wax is a low molecular weight polypropylene homopolymer or copolymer widely used in coatings. The so-called wax refers to the polymer that is ultimately distributed in microcrystalline form on the surface of the coating, playing a practical role similar to wax and more diverse. Wax plays an increasingly important role as an additive in coatings and inks.
The function of polypropylene wax depends on the following factors: the variety and specifications of polypropylene wax, the final particle size formed, the ability to migrate to the surface of the coating film, the composition of the coating, the properties of the coated substrate, and the construction application method.

The role of polypropylene wax:
1. Extinction: Different types of wax have different effects on the gloss of the coating film; From significant extinction to increased gloss, as well as producing the same gloss and hammer pattern. Hand feel: The wax additive gives the coating a good hand feel, which is beyond the reach of other matting agents.
2. Wear resistance: Resistance to scratches, wear, polishing, and engraving. One factor in improving resistance to friction and scratches is to reduce the friction coefficient of the coating surface, so that when objects come into contact with the coating surface, the sliding tendency is greater than the scratch tendency.
