Advantages of oxidized polyethylene wax in waterborne coatings
2021-01-02
Oxidized polyethylene waxes contain a certain amount of hydroxyl groups in the molecular chain, and their solubility with polar resins has been significantly improved and is superior to that of polyethylene waxes. Rubber, plastic, paraffin and other materials have good compatibility in the external lubrication balance of polyvinyl chloride. In transparent hard PVC formulations with oxidized polyethylene waxes the lubricity is superior to other lubricants. Any number of acids greater than 13 can be used as an emulsion type.
Oxidized polyethylene wax in the waterborne coating industry is widely used in food packaging containers, textiles, resin finishing agents, softeners, printing inks, waterborne coatings, printing pastes, waterborne varnish, etc. Oxidized polyethylene wax in waterborne coatings in the application of the field covers the waterborne industrial paints, waterborne wood paints, waterborne plastic paints, waterborne architectural paints. It can improve the surface hardness of the coating, adjust the gloss of the coating (gloss enhancement, matting, polishability), adjust the coefficient of friction of the coating (slip enhancement or anti-slip), adjust the feel of the coating (slippery, astringent, oily, etc.), anti-adhesion, anti-scratch, water repellant, anti-embroidery, and other application effects. Application Mechanism of Oxidized Polyethylene Wax in Waterborne Coatings: The product is provided in the form of suspension of wax particles, which migrate to the surface of the coating to form a protective layer and at the same time change the surface properties of the coating. Generally finely dispersed wax emulsions are used for varnishes and wax dispersions with micron-sized particle sizes are used for color paints.
Oxidized polyethylene wax has high hardness, high slip, high toughness and good chemical stability, it is a popular coating protection material suitable for coatings with anti-slip requirements; it can improve the sandability of coatings; oxidized polyethylene wax has unique applications in the coatings industry. We can provide anionic, non-anionic, and cationic emulsions that are suitable for different resin systems by varying the emulsification formulations and processes and customize the products to suit the customer's requirements.
