Water-based environmental protection materials in many fields slowly replace the oil solvent, become a trend of industry development, and as a water-based coating species need not be less water-based wax emulsion products, because of its unique performance and role, widely used in water-based coating materials.
1, Change the surface performance of the coating, to protect the coating, adjust the gloss and other functions.
Most of the waxes in water-based surface coating formulations are used to change the surface properties of the coating, such as improving the slip or anti-slip, anti-abrasion, anti-adhesion, changing gloss, water repellency, rust prevention, etc. In use, the wax particles need to occupy the coating surface during the drying of the coating, forming an isolation layer, thus playing a protective role.
2, Wax emulsions are applied as special coating resins
Wax emulsions, especially micro emulsions, have certain film-forming properties in order to form coatings on substrates. Since wax has excellent hardness, polishability, feel, water repellency, good chemical resistance stability and non-toxicity, coatings with wax emulsion as the theme are commonly used in the field of polish, water resist and rust-proof coating.
3, Isolation and bonding
Wax is generally considered to have better anti-adhesive and isolation, so it is often used as mold release agent, isolation agent and other products in the field of paper, rubber and plastic processing, metal die-casting, etc., where polyethylene wax emulsions are used more often. But it is interesting that in the paper products and PE, PP film bonding packaging with water-based sealant products, there are formulations using polyethylene wax emulsion and pine tongue, VAE emulsion compound, to achieve good results. Polyethylene wax emulsion in the formulation mainly to increase the role of adhesion with PE, PP film.
