The use of polyethylene wax in ink? High temperature should be avoided when polyolefin wax is added to paint or ink, because polyolefin wax will dissolve in the solvent at high temperature, and precipitate out during cooling to form larger particles.
The effect of polyene wax depends on the following factors: the variety and specification of the polyene wax, the final particle size, the ability to migrate to the surface of the coating and the composition of the coating, the properties of the substrate to be coated, and the method of application. law, etc. As an additive, polyene wax is not only used in solvent-based coatings and inks, but also used in water-based coatings and inks.

The performance of polyethylene wax:
1. Good matting properties are used in matting coatings, and its dosage is within the same range as the amount of silicon oxide used to play an effective matting effect. The magnitude of the matting effect depends on the particle size 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, stain resistance.
2. Anti-scratch, anti-wear, anti-polishing, anti-marking One factor to improve anti-friction and anti-scratch is to reduce the friction coefficient of the coating surface, so that when the object touches the coating surface, the sliding tendency is greater than that of scratching. In this regard, the effect of polyethylene wax is similar to that of silicone oil, except that the former exists in the form of fine dispersed particles on the surface of the coating. Only a small amount is required to achieve scratch resistance. The use of micronized waxes in printing inks can significantly improve the abrasion resistance of the inks.
3. Anti-adhesion Some workpieces, such as white or metal objects, often need to be stacked in a short time after coating. The progress of printing technology also requires ink to avoid smearing of printed materials. Polyethylene wax can prevent sticking and smearing caused by the accumulation and overlapping of production or prints.
4. Anti-precipitation, anti-sag, thixotropy. Orientation to metallic pigments. Polyene waxes, dispersed in aromatic and aliphatic solvents, can increase the settling resistance of coatings and inks, and it also exhibits varying degrees of thixotropy, sag resistance, and orientation to metallic pigments.
