Silicone Leveling agent is a common auxiliary agent used in ink. It can promote the formation of an uniform and smooth film during the drying process of ink. There are many types of leveling agents, and different inks use different types of leveling agents. Silicone leveling agent can improve the wettability of the substrate, affect the surface flow, and play an important role in improving the leveling effect of ink. After the solvent evaporates, the silicone resin will form a monomolecular layer on the surface of the ink film and make the gloss of the ink film better.
