What role does polyethylene wax play in coatings and paints

Paint is often encountered in daily life and has become an indispensable part of life. It makes industrial products, cars, machinery, and other metal products look beautiful and durable after painting. However, the paint on the metal surface can be affected by air, moisture, and temperature due to long-term use, which can easily cause paint detachment and affect its aesthetics, preventing a decrease in metal corrosion/corrosion ability. Polyethylene wax has good cold resistance, heat resistance, and stability, and is widely used in coatings and paints. Now, Qingdao Sainuo editor will introduce it to you:

1. Polyethylene wax has a relatively high melting point and can delay plasticization. In paint, after cooling, a thin layer of wax film can be formed on the coating surface. This layer of wax film can effectively resist scratches and rust during brushing.
2. Pe wax has a moderate viscosity and can effectively disperse and lubricate pigments and carriers during the coating production process, preventing them from clumping and causing protrusions that may affect the appearance during the coating process.

3. Polyethylene wax has been used as a paint matting agent for a long time, characterized by its simple use. After coating application, due to solvent evaporation, wax in the paint precipitates, forming fine crystals that float on the surface of the paint film, forming a rough surface that scatters light and plays a role in extinction.

4. The main functions of polyethylene wax in solvent based coatings are: extinction, anti precipitation, Thixotropy, good lubrication and processability, and metal positioning.

5. Adding polyethylene wax powder to coatings should avoid high temperatures, as polyethylene wax will dissolve in solvents at high temperatures and precipitate during cooling, forming larger particles.
Some workpieces, such as wooden or metal objects, often need to be stacked up in a short period of time after coating, and advances in printing technology also require ink to avoid rubbing and smudging of printed materials. Polyethylene wax can prevent adhesion and smudging caused by accumulated overlap in production or printing.
