Why choose to add oxidized polyethylene wax in powder coatings?

    In powder coatings, waxes are widely used, with main functions including improving coating hardness, smoothness, degassing and defoaming, preventing caking, wetting and dispersing, aiding leveling, and adjusting gloss.

    Forms of waxes used in powder coatings: micro-powder, powder, granule, flake, etc. For external addition in powders, they must be micro-powder varieties with good compatibility. Powder form offers excellent dispersion and better leveling assistance.

    Oxidized polyethylene wax, also known as OPE wax, is an excellent new type of polar wax made from polyethylene wax through oxidation process. Its molecular chain contains carbonyl and hydroxyl groups, so it has good compatibility with rubber, plastics, paraffin, pigments, fillers and polar resins. It is in the form of white to slightly yellowish powder or granules and has good chemical stability.

What are the characteristics of oxidized polyethylene wax?

    Oxidized polyethylene wax has low viscosity, high softening point, good hardness, non-toxicity, non-corrosiveness and good thermal stability. It has good dispersibility for fillers and pigments, excellent moisture resistance at room temperature, strong chemical resistance and excellent electrical properties.

What is the role of oxidized polyethylene wax in coating formulations?

    Oxidized polyethylene wax is widely used in water-based coatings and ink formulations. It can improve the surface performance of coatings, providing excellent abrasion resistance, anti-blocking and scratch resistance. Adding oxidized polyethylene wax can also improve the rheological properties of liquids, making paints and coatings more uniform and labor-saving during use. It can also make the color of coatings brighter and less prone to color difference. In addition, adding oxidized polyethylene wax to coating formulations will not affect the original important properties of the product!
