Description
Silphobic 90 is fine particle hydrophobic silica. Silphobic 90 contains larger than 2 % chemically bound carbon and is therefore not wettable by water. The wettability of Silphobic 90 with methanol is approx. 50 % and indicates its highly hydrophobic character. Silphobic 90 can be used as anti-caking agent and is also suitable to be used in a great variety of defoamer.
