Polyethylene wax

Polyethylene wax (tissuemat E) is a kind of chemical material, in which the color of polyethylene wax is small white bead / sheet, which is formed by the processing agent of ethylene polymerized rubber. It has the characteristics of high melting point, high hardness, high gloss and white color.

Polyethylene wax is a homopolymer or copolymer of low molecular weight polyethylene widely used in coatings. The so-called wax means that the polymer plays a similar but more practical role in the coating surface in the form of microcrystalline floating cloth.

The main functions of polyethylene wax in solvent coating are: extinction, scratch resistance, wear resistance, polishing resistance, printing resistance, adhesion resistance, precipitation resistance, thixotropy resistance; good lubricity and processability; metal pigment positioning.

The action principle of polyethylene wax is as follows: polyethylene wax dissolves in the solvent at high temperature (about 100-140 ℃), and precipitates out in the form of microcrystalline in the coating when it is cooled to normal temperature. Because of its thixotropy, it is conducive to the storage of the coating. After the application of the coating, it can migrate to the surface of the coating during the solvent evaporation process, and finally form a "wax" with other components of the coating ”The surface layer of.

The function of polyethylene wax depends on the following factors: the variety and specification of polyethylene wax, the fineness of particles finally formed, the ability to migrate to the coating surface, the composition of the coating, the nature of the coated substrate, the construction and application method, etc.
