What is the ink leveling agent? What are the benefits?

Leveling agent is a common ink additives, it can promote the formation of the ink of a smooth, uniform coating film in a film forming process. Many types of leveling agent, leveling agent streams of different types of ink used are not the same. Solvent-based leveling agent mainly high-boiling solvent mixtures. Leveling agent used multiple types of polyurethane-based. Long chain silicone compatibility restricted commonly are poly dimethyl siloxanes, poly (methylphenyl) siloxanes, organic-modified polysiloxane. Such materials can improve the wettability of the substrate and the control flow on the surface effects play a role to improve the leveling, after evaporation of the solvent, a silicone resin coating the surface of the monolayer formation, improve the gloss of the coating film. Fluorine-based surfactants, the main component of polyfluorinated polyenes, for many resins and solvents also have good compatibility and surface activity, help to improve the wetting, dispersing and leveling.
By chromatographic and spectroscopic identification of the chemical composition may know.
