Application Of Oxidized Polyethylene Wax(OPE Wax) In Water Coating

The application of oxidized polyethylene wax in water paints shows that the properties of water-based paints such as boiling water resistance, resistance to organic media, fullness of wood decorative paints, resistance to sticking and washing, and mechanical strength are relatively weak. This hinders the further promotion and application of water-based coatings. The emergence of wax emulsions effectively alleviates these problems.

The wax emulsion is roughly evenly dispersed in the system. After application, the distribution of wax particles has a glossy film surface after the paint film impacts the surface, and because of the particle size distribution of different types of wax additives, when proceeding , it will produce different degrees of diffuse reflection after light irradiation, which will have different effects on the gloss of the coating film.

1. Improved coating gloss. It is generally believed that the greater the change in the particle size of the wax emulsion, the more obvious the gloss effect; in addition, there is a certain relationship between the glossiness of the coating and the crystallinity of the wax. The particle size of wax emulsion has reached the nanometer level, making it a good surface protectant for high-gloss ink systems.

2. Provide high smoothness, high wear resistance and scratch resistance. The use of wax emulsion can not only improve the scratch resistance of the paint film, but also affect the adhesion and anti-gloss of the paint film. After the polyethylene wax emulsion is added to the water-based paint, during the film formation process, the wax drifts to the surface of the coating film and is evenly dispersed. A layer of wax protective film will be formed on the coating film, thereby reducing the friction coefficient; this can improve The coating’s friction resistance improves slip and scratch resistance.
