What PE waxes are used in inks? Polyethylene wax can be used in PE, PP films, moisture-proof cellophane, plastics, etc. for packaging materials such as fructose, milk, juice, skin care products, medicine bottles, detergents and food, and other inks such as offset printing ink Among others, it has a satisfactory effect as an ink wear-resistant agent.

PE wax is mainly based on bearing effect and floating effect. The bearing effect is that the particle size of the polyethylene wax itself is similar to or slightly larger than the thickness of the ink coating, so it is exposed, allowing the wax’s scratch-resistant and anti-abrasion properties to be revealed. The floating effect means that due to the particle shape of the polyethylene wax powder, the wax drifts to the surface of the coating film and is evenly dispersed during the film formation process, so that the upper layer of the coating film is protected by wax, making the wax scratch-resistant and anti-scuff. specialty.

1. Matting effect: In the process of preparing printing ink, in order to improve some properties of printed products, polyethylene needs to be added to the printing ink system to provide scratch resistance, wear resistance, anti-adhesion and smoothness. If you want matting performance, you can choose polyethylene wax with a coarser particle size, and at the same time, you also need the ability of the dispersed particles to perfectly migrate to the surface of the paint film.
2. Anti-scratch, anti-wear, anti-polishing, anti-marking: Polyethylene wax, added to the paint, can greatly reduce the tendency to be polished due to friction, while maintaining low-gloss durability. It is often used in applications. Much needed.
3. Anti-adhesion: Some workpieces, such as wood or metal objects, often need to be stacked in a short time after coating. The advancement of printing technology also requires inks to avoid smearing of printed matter. Polyethylene wax can prevent adhesion and smudging caused by production or accumulation and overlap of printed matter.
4. Anti-sedimentation, anti-sag, and thixotropy: positioning properties for metallic pigments. Polyolefin wax is dispersed in aromatic and aliphatic solvents and can increase the anti-sedimentation of coatings and inks. It also shows varying degrees of thixotropy, anti-sag and positioning properties for metallic pigments.

In addition, polyethylene wax has properties such as reducing agglomeration, peeling, and resisting stains, which improves the performance of the ink during the reprinting process and also improves the quality of the product.
