How is polyethylene wax used in waterborne coatings? As we all know, polyene wax has stable chemical properties, smooth feel, high hardness and good wear resistance. It is often added to various industries, such as dispersants, brighteners, slip agents, etc. The coating industry is the most widely used.
Application of Polyethylene Wax in Waterborne Coatings:
(1) High slip, high wear resistance and scratch resistance
After the polyene wax emulsion is added to the water-based paint, during the film-forming process, the wax drifts to the surface of the paint film and disperses evenly. A protective wax film will be formed on the paint film, and the friction coefficient will be reduced accordingly; this can improve the Slip and scratch resistance of the coating.
(2) The gloss of the coating is improved
The smaller the particle size of the wax additive, the more obvious the improvement of gloss; the larger the particle size, the more obvious the improvement of anti-abrasion
The influence of the particle size of the emulsion on the gloss of the coating. The visible light wavelength is 400-700 nm. When the particle size of the polyene wax emulsion is less than 1/2 of the visible light wavelength, that is, ≤ 200 nm, light diffraction will occur. , thereby increasing the gloss of the coating. It is generally believed that the larger the particle size change of the wax emulsion, the more obvious the gloss effect; in addition, the gloss of the coating has a certain relationship with the crystallinity of the wax. The particle size of wax emulsion has reached nanometer level, which is the best surface protection for high gloss ink system.
Oxidized polyethylene emulsions commonly used in water-based coatings have a melting range of 90 to 145 °C, are light-colored and translucent, are odorless, and have excellent strength and toughness. Preferred wax. Polyethylene wax emulsion is widely used in food packaging containers, textiles, resin finishing agents, softeners, printing inks, water-based coatings, printing glues, water-based varnishes (whitening, shoemaking, paper products, shoes latex, adhesives, car care, floor care), etc.
In the future, the application of polyene wax will become more and more extensive, so the quality requirements of polyene wax will become higher and higher.
