Application of Polyethylene Wax Powder in Paint and Ink

The performance of polyethylene wax

1, good extinction

In the application of matting coatings, the amount of silica used in the same range that is effective extinction effect. The amount of extinction depends on the fineness of the dispersed polyethylene wax and its ability to migrate to the surface of the paint film.

As a matting agent, its outstanding advantages are: excellent transparency, smoothness, soft appearance, chemical inertness, non-precipitation, scratch resistance, abrasion resistance, and stain resistance.

Its comprehensive performance is far from comparable to other matting agents.

Polyethylene waxes are commonly used as matting agents in: 1, Nitro varnish; 2. Acid-cured varnish; 3. Polyurethane varnish; 4. Polyester varnish to produce high-quality plain varnish.

2, anti-scratch, anti-wear, anti-polishing, anti-imprinting

One factor to improve friction and scratch resistance is to reduce the coefficient of friction on the surface of the coating. When the object touches the surface of the coating, the sliding tendency is greater than the scratching tendency. The effect of the polyethylene wax is similar to silicone oil. The difference is that the former Fine dispersed particles are present on the surface of the coating.

To achieve scratch resistance requires only a small amount.

Scratch resistance is especially important for high-grade wood coatings and other decorative paints.

Polyethylene wax, added to the coating can greatly reduce the tendency to be rubbed and polished, while maintaining low gloss durability is often desirable in applications. In alkyd varnish, when the amount of polyethylene wax is 1.5%, the anti-wear value of the coating film is doubled, but when the amount is 3%, the anti-wear value is increased by 5 times.

When metal objects come into contact with coated products, they sometimes leave a black mark on the coating. The addition of polyethylene wax to the film can reduce this tendency, or make the mark easy to wipe off.

The use of micronized wax in printing inks can significantly improve the abrasion resistance of the ink.

3, anti-blocking

Some workpieces, such as wood or metal objects, tend to pile up in a short period of time after the film is coated. Advances in printing technology also require the ink to avoid contamination of the printed material.

Polyethylene waxes can prevent sticking or stains caused by the cumulative overlap of production or printed materials.

4, anti-precipitation, anti-sag, thixotropic. Positioning of metallic pigments.

Polyethylene waxes dispersed in aromatic and aliphatic solvents can increase the anti-precipitation properties of coatings and inks. It also shows varying degrees of thixotropy, sag resistance, and localization of metallic pigments.
