Silicone Defoamer for Coatings and Paints

Most of the silicone defoamer used in coatings are hydrophobic silicone emulsions. With silicone as component, they are more expensive than mineral oil defoamers.So they are mainly applied in high-end coatings. The hydrophobic particles of silicone defoamers can also improve defoaming and dispersion performance. Its main advantage is that the gloss will not be reduced and the color of pigment concentrate will also not change.
