The wet grinding process occurs when a product is transformed from solid to liquid, regardless of its viscosity: paints, inks, enamels, nail varnish, among others. In this process, agglomerates that were not separated in the dispersion phase (due to the electro-physical bonding of some components) are broken by applying extra energy.. This wet …
