Precipitated Silica For Printing Ink and Paint

◆Description of products

The product is produced by the reaction of commonly hydrophile silicon dioxide and a certain chemical material 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 also the function of defoaming.

◆Application Scope

The thixotropy of silica is the major factor that helps to improve the performances of traditional paints. Take the wall paints used in construction as an example, silica can well prevent paint delamination and sags. Such paints demonstrate great application property and contamination resistance, and they show excellent self-cleaning performance and adhesion. It is reported that they are washable for more than 1,000 times.
