How does pe wax work in ink? The role of polyene wax in ink is very important. Common ones include matting, anti-scratch, abrasion resistance, anti-blocking, etc. Different types of polyene wax of Tianshi play different roles. The main reason is that it depends on the size and composition of the particle size of the product model.
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.
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. Polyethylene waxes, when added to coatings, can greatly reduce the tendency to be rubbed and polished, while maintaining low gloss durability is often required in applications.
3. Anti-blocking 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 products. Polyethylene wax can prevent sticking and smearing caused by accumulation and overlapping of production and printing.
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.
In addition, pe wax can also reduce the disadvantages of caking, scratching, and smearing, and improve the printing performance of the ink.
