Polyethylene wax is widely used

Polyethylene waxes are low molecular weight polyethylene homopolymers or copolymers widely used in coatings. The so-called wax means that the polymer is finally floated in the form of microcrystals, which plays a similar role to paraffin wax but more than paraffin wax in the surface layer of the coating.
The main functions of polyethylene wax in solvent-based coating film are: matting, scratch resistance, wear resistance, polishing resistance, anti-engraving, anti-blocking, anti-precipitation, thixotropy; Good lubricity and processability; Metal pigment locality.
The principle of action of polyethylene wax is as follows: polyethylene wax is dissolved in the solvent at high temperature (about 100-140 °C), and precipitated when cooled to room temperature, and exists in the form of microcrystalline in the coating, because of its thixotropy is conducive to the storage of the coating, and after the application of the coating, it can migrate to the surface of the coating film during the solvent volatilization process, and finally form a "waxed" surface layer with other components of the coating.
The role of polyethylene wax depends on the following factors: the variety and specification of the polyethylene wax, the fineness of the particles formed in the end, the ability to migrate to the surface of the coating film and the composition of the coating, the nature of the substrate to be coated, the construction application method, etc.
