Introduction to Polyethylene Wax

- Feb 17, 2019-

Polyethylene wax (Tissuemat E) is a chemical material, in which the color of polyethylene wax is white small bead-shaped/flake, formed by ethylene polymerization rubber processing agent, which has the characteristics of high melting point, large hardness, high gloss, color white and so on.

Polyethylene wax is a low molecular weight polyethylene aggregates or copolymers widely used in coatings.

The so-called wax, means that the polymer is finally in the form of microcrystalline float in the coating surface of similar paraffin, but also more diverse and practical than paraffin.

The main functions of polyethylene wax in solvent-based coating are: extinction, scratch resistance, anti-wear resistance, anti-polishing, anti-engraving, anti-adhesion, anti-precipitation, thixotropy, good lubrication and processability, metal pigment positioning.

The principle of the action of polyethylene wax is as such: polyethylene wax in the high temperature (about 100-140 ℃) dissolved in solvents, and in cooling to normal temperature precipitation, in the form of microcrystalline in the coating, because its thixotropy is conducive to the storage of paint, and after the application of paint construction, in the solvent evaporation process can be migrated to the surface of the coating film. Eventually form a "waxy" surface with other components of the coating.

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