Fumed Silica Powder For Industrial And Printing Inks

Specification QX-151 is hydrophobic fumed silica with surface treatment of DDS (Dimethyldichlorosilane), which is manufactured with  basis on hydrophilic fumed silica with specific surface area of 150 m2/g. It is a kind of high purity white colloidal powder. Silica matting agents are commonly used in various industries, including coatings, inks, and plastics, to provide a matte  appearance to the final product. Hydrophobic fumed silica is a type of silica matting agent that has been treated to be  water-repellent. Hydrophobic fumed silica is produced by treating fumed silica with various hydrophobic agents, such as silanes or siloxa -nes. This treatment modifies the surface of the silica particles, making them water-repellent and reducing their affinity for  moisture.When used as a matting agent, hydrophobic fumed silica can be dispersed in a variety of binders or resins to achi -eve the desired matte effect.
