Avirulent Insipidity Hydrated Silicon Dioxide , Amorphous Silica Alumina For Anti Settling Agent

Precipitated Silica Used As Thickening Agent, Anti-Setting Agent and Matting Agent

Description

Precipitated Silica in Coatings widely used as thickening agent, anti-settling agent and matting agent. The general process is to attain silicate liquid by the acid neutralization reaction of sodium silicate solution, then processing it with filtering, washing, drying, finally let is go through our advanced crushing equipment for ultrafine grinding. It is a kind of virulent insipidity, nonflammable fluffy white powder, which is soluble in caustic soda and hydrofluoric acid only. Other characteristics are no decomposition, discoloration under high temperature, but with certain water imbibitions.

Characters

1, In solvent-based coatings, it also increases viscosity for settling resistance. In clear coatings such as lacquer or varnish, it offers exceptionally high clarity and transparency.

2, Flow&Levelling, Smoothness and Stain& Scrub Resistance.
