Hydrophobicity White carbon black
 

 
Feature of Hydrophobicity White carbon black:
  It makes that general hydrophilia silicon dioxide reacts with silane coupling agent under the right conditions to form solid powder-like silicon dioxide, on whose surface there is polysiloxane stem grafting. Its contact angle of hydrophobic is from 70 to 150. It also has good hydrophobic and defoaming function.
