Silicone additives for coatings can improve the production process of coatings, maintain the storage stability of coatings, improve its construction technology, improve product quality, give some special functions of coatings, has become an indispensable component of coatings. Reasonable and correct selection of organosilicon additives can reduce the cost and improve the benefit. Silicone additives used in coatings mainly include silicone oil emulsion or dispersion, silicone elastomer emulsion or dispersion, silicone resin, silicone resin modified silicone resin, silane coupling agent, alkyl or aryl alkoxy silane, fluorosilicone polymer, polyether modified silicone.. (silicone surfactant) and so on, their effect in the coating is mainly leveling, scratch resistance, anti-adhesion, pigment dispersion, smoothing, surface special effects (such as hammer lines, etc.), hydrophobic, wetting, adhesion promotion, anti-adhesion, foam inhibition, defoaming, brightness or extinction. Different coating systems, the selection of silicone additives are also different; But each silicone additive has multiple functions and can sometimes be used in other systems.
