Polyethylene wax

Polyethylene wax is a chemical material in which the color of polyethylene wax is small white beads / sheets, which are formed from ethylene polymerized rubber processing agent. High, white and other characteristics.

Polyethylene wax is a low molecular weight polyethylene homopolymer or copolymer widely used in coatings. The so-called wax means that the polymer is finally floated in the form of crystallites in the surface layer of the paint to play a similar but more practical role than paraffin.

The main functions of polyethylene wax in solvent-based coatings are: matting, scratch resistance, abrasion resistance, polishing resistance, anti-marking, anti-blocking, anti-settling, thixotropy; good lubricity and processability; metal pigment positioning Sex.

The working principle of polyethylene wax is this: polyethylene wax is dissolved in the solvent at high temperature (about 100-140 ℃), and precipitates when cooled to normal temperature, and exists in the coating in the form of crystallites because of its thixotropy It is conducive to the storage of paint, and after the application of paint construction, it can migrate to the surface layer of the coating film during the solvent evaporation process, and eventually form a "waxed" surface layer with other components of the paint.

The role of polyethylene wax depends on the following factors: the variety specifications of polyethylene wax, the final particle size, the ability to migrate to the surface of the coating film and the composition of the coating, the nature of the coated substrate, the construction application method, etc.
