The Role Of Polyethylene Wax Powder In Coatings

The role of polyethylene wax powder in coatings. In the polyethylene production process, a small amount of oligomers, that is, low relative molecular weight polyethylene, will be produced, also known as high molecular wax, or polyethylene wax for short. . It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance.

High molecular weight wax is a good desensitizing agent for explosives. It can also be used as a dispersing lubricant for plastics and pigments, a moisture-proof agent for corrugated paper, a hot-melt adhesive and ozokerite, and a car beauty wax.

High molecular wax is a non-toxic, odorless, non-corrosive, white or slightly white solid with a relative molecular mass of 1800-8000. It has good chemical stability, excellent temperature resistance, drug resistance and electrical properties at room temperature, and has a wide range of applications. It can be used as a raw material for chlorinated polyethylene, a modifier for plastics, and a coating agent for textiles. and additives to improve the viscosity of crude oil and fuel oil.

The role of polyethylene wax powder in coatings:
1. The application and function mechanism of high molecular wax in coatings. Waxes used in coatings are mainly added in the form of additives. Wax additives generally exist in the form of water emulsions. They were originally used to improve the surface anti-expansion of coating films. performance.
2. Mainly includes improving the smoothness, scratch resistance and water resistance of the coating film. In addition, it can also affect the rheological properties of the paint. Its addition can make the orientation of solid particles such as aluminum powder in the metallic flash paint uniform.
3. It can be used as a matting agent in matte paints. The matting effects of wax additives vary according to their particle size and particle size distribution. Therefore, wax additives are suitable for both glossy and matte paints.
4. Microcrystalline modified polyolefin wax can be used to improve the surface properties of water-based industrial coatings. After adding it, the smoothness, anti-adhesion, scratch resistance and matting effect are enhanced, and it can effectively inhibit pigment precipitation.

Polyethylene wax powder can play anti-slip, anti-adhesive, stain-resistant, abrasion-resistant, anti-scratch, anti-sag, anti-sediment, matting and other effects in coatings. Polyethylene wax and polytetrafluoroethylene wax are combined Used together, it can improve anti-adhesion and friction resistance; polyethylene wax can be used together with silicon dioxide or silicone oil to enhance matting and friction resistance.
