The Role Of Synthetic Waxes In Paint Coatings

The effect of adding synthetic wax to paint coatings, PE synthetic wax, also known as polymer wax or polyolefin wax for short. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and abrasion resistance.

PE synthetic wax has good matting properties. When used in matting coatings, its dosage is within the same range as the amount of silica, which can effectively matt. The magnitude of the matting effect depends on the particle size of the dispersed polyvinyl wax and its ability to migrate to the surface of the paint film. As a matting agent, it has outstanding advantages such as transparency, smoothness, non-sedimentation, scratch resistance, abrasion resistance, and stain resistance. Its comprehensive performance is far beyond that of other matting agents.

One of the factors to improve friction and scratch resistance is to reduce the friction coefficient of the coating surface, so that when an object touches the coating surface, the sliding tendency is greater than the scratch tendency. In this regard, the role of polyethylene synthetic wax Similar to silicone oil, the difference is that the former exists in the form of fine dispersed particles on the coating surface. Scratch resistance is especially important for high-grade wood lacquers and other highly decorative coatings.

Synthetic waxes, added to paints, can greatly reduce the tendency to be polished by friction, while maintaining the durability of low gloss, which is often required in applications. When metal objects come into contact with a coated product, they sometimes leave black marks on the film, polyvinyl waxes added to the film can reduce this tendency, or make the marks easier to wipe off. The use of micronized waxes in printing inks can significantly improve the abrasion resistance of the inks.

Polyethylene wax(PE Wax) Synthetic wax can prevent sticking and smearing caused by accumulation or overlapping of printed matter. Polyethylene wax is dispersed in aromatic and aliphatic solvents, which can increase the anti-sedimentation of coatings and inks. It also shows different degrees of thixotropy, anti-sagging and positioning of metallic pigments.
