Superiority
Hydrophobic silica is commonly after reprocessing of products, under some appropriate conditions will generally hydrophilic silica and silane coupling agent treatment response, and obtained a kind of surface has polysiloxane grafting of solid powder silica, the hydrophobic contact Angle can reach 70 to 150, has the good hydrophobic property.
