        Introduction of the role of polyethylene wax micropowder

        Release date:2016-07-27 Author: Click:

        Introduction of the role of polyethylene wax micropowder. Polyethylene waxes are low molecular weight polyethylene homopolymers or copolymers that are widely used in coatings. By wax, it is meant that the final distribution of the polymer in the form of crystallites on the surface of the coating acts like wax and more diverse.

        Polyethylene wax

        Hecai Chemical pointed out that the role of polyethylene wax micropowder is mainly as follows:


        1. Improve surface gloss:


        In the application of matting coatings, the amount used in the same range of silica is effective to eliminate the light. The magnitude of the matting effect depends on the fineness of the dispersed polyethylene wax and the ability to migrate to the surface of the coating film.


        2, anti-scratch, anti-wear, anti-polish, anti-marking:


        One factor to improve the anti-friction and scratch resistance is to reduce the friction coefficient of the surface of the coating, so that the sliding tendency of the object when contacting the surface of the coating is greater than the tendency of scratching. In this respect, the effect of polyethylene wax is similar to that of silicone oil. The difference is that the former Fine dispersed particles are present on the surface of the coating. It takes only a small amount to achieve scratch resistance.


        Polyethylene wax, which is added to the coating, greatly reduces the tendency to be rubbed and polished, while maintaining low gloss durability is often desirable in applications. For example, in the alkyd varnish, when the amount of the polyethylene wax is 1.5%, the anti-wear value of the coating film is doubled, and when the amount is 3%, the anti-wear value is increased by 5 times.


        3, anti-blocking:


        Some workpieces, such as wood or metal objects, tend to stack up in a short period of time after coating. Advances in printing technology also require inks to avoid staining of printed matter.


        4, anti-precipitation, anti-sagging, thixotropic. Positioning of metallic pigments:


        Polyethylene wax is dispersed in aromatic and aliphatic solvents to increase the precipitation resistance of coatings and inks. It also exhibits varying degrees of thixotropy, sag resistance and localization of metallic pigments.
