Generally, wet grinding allows for finer particle size reduction than dry grinding and is widely used for dispersion and other applications. Grinding in a solvent enables efficient application of force to the material being ground. The grinding media and the material are forcibly stirred in the solvent to carry out the grinding process. It is utilized in a wide range of fields, particularly for the fine processing of high-density electronic materials and the dispersion of pigments in paints.

Soap-free colloidal emulsion This is a soap-free colloidal emulsion primarily made from polyethylene-based resin, blended with various crosslinking agents and additives for different properties. After the evaporation of moisture, it forms a film with a crosslinked structure, which does not re-dissolve in water and has very low hygroscopicity.
