How to use polyethylene wax(PE Wax) powder in ink? Wax was used earlier as a matting agent in paints and is characterized by its simplicity of use. After the paint is applied, due to the volatilization of the solvent, the wax in the paint precipitates, forming fine crystals that float on the surface of the paint film, forming a rough surface that scatters light and plays a matting role.
High molecular weight wax is used as a matting agent. Its dosage is 0.5-3%. It is suitable for acrylic paint, alkyd paint, nitrocellulose paint and polyurethane paint, industrial baking paint, vinyl paint and latex paint. The combined use of high molecular wax and pneumatic silica can improve the performance of the paint film, and its matting effect, water resistance, chemical resistance, scratch resistance, abrasion resistance and interlayer adhesion are all significantly improved.
Polyethylene wax is a low molecular weight polyethylene homopolymer or copolymer widely used in coatings. The so-called wax refers to the fact that the polymer eventually becomes microcrystalline and is distributed on the surface of the coating, playing a variety of practical roles similar to wax.
The main functions of polyethylene wax in solvent-based coatings are: matting, anti-sedimentation, thixotropy, good lubrication and processability, and metal positioning.
High temperatures should be avoided when adding polyolefin wax micropowder to coatings, because polyolefin wax will dissolve in the solvent at high temperatures and precipitate when cooled, forming larger particles.
The effect of polyolefin wax depends on the following factors: the variety and specification of the polyolefin wax, the fineness of the final particles, the ability to migrate to the surface of the paint and the composition of the paint, the nature of the substrate to be coated, and the construction application method wait. As an additive, polyethylene wax is used not only in solvent-based coatings and inks, but also in water-based coatings and inks.
