The main production process makes generally hydrophilic silica under the condition of appropriate reaction with a silane coupling agent and made a solid surface with polysiloxane grafted powder silica, the hydrophobic contact Angle can reach 70-150, not only has good hydrophobic, at the same time also has the function of foam. Main Application:
Modified White Carbon Black Hydrophobic Silica for Spin printing, defoaming agent, lubricant, unsaturated polyester resin, powder fire extinguisher etc.
SIPERNAT® D 10. SIPERNAT® D 10 is a milled hydrophobic precipitated silica. This silica is highly hydrophobic, thus not wettable with water. It is used in a great variety of defoamers due to its high effectiveness in foam destruction. Moisture-sensitive powders benefit from this grade as highly efficient flow and anticaking agent.
The antifoaming agen does not only have a good antifoaming effect and suds lasting effect. 3. It can be used for silicone oil lubricant additive Water-based antifoaming agent and foam inhibition in additives. 4. It can be used for silicone oil lubricant additive Water-based antifoaming agent in …
A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Commonly used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols.
There are 1,430 hydrophobic agent suppliers, mainly located in Asia. The top supplying countries or regions are China, Taiwan, China, and South Korea, which supply 97%, 1%, and 1% of hydrophobic agent respectively. Hydrophobic agent products are most popular in Domestic Market, Southeast Asia, and North America.

a superior hydrophobic silica emulsion in oil, useful principally as an antifoaming agent, is prepared by starting with a silica hydrosol emulsified oil. water is stripped from the emulsion and the emulsion system is then reacted with a polysiloxane which renders the oil-dispesed silica particles (sol dimension) hydrophobic.
