Application of polypropylene wax in coatings and inks
2024-03-06
Wax is used earlier as a coating and ink additive, which is characterized by simple use. After coating construction, due to solvent volatilization, wax in the coating precipitates, forming fine crystals, floating on the surface of the coating film, which plays a variety of roles in improving the performance of the coating film. Now, in addition to polymer mineral wax, natural wax is rarely used in coatings and inks. Instead, polymer wax and their modified derivatives are used. They can give the film good water resistance, moisture and heat resistance, scratch resistance, extinction, anti fouling, and good hand feel. Their scratch resistance is beyond the reach of pigment extinction. Polypropylene wax is a low molecular weight polypropylene homopolymer or copolymer widely used in coatings.
