Feature of products:
It is produced by the reaction of commonly hydrophile silicon dioxide and a certain chemical meterial in the appropriate condition. It is a kind of solid powder silicon dioxide whose surface has polysiloxane and its distant water angle is 70-150. It has not only excellent distant water capability but alsi the functiong of defoaming.
