Paint Silicon Dioxide Cheap Silica Matting Agent For Industrial Coating
Product Description
A matting agent used in industrial coatings that exhibits amorphous silica synthesized from white powder.It has very high extinction rate, high transparency and excellent coating appearance.It is a fine precipitated silica matting agent suitable for solvent - based and water - based systems.
Feature
- High Transparency
Products in high purity guarantees refractive index complies with resin index. - Excellent Dispersing Property
Featured production techonology process makes heat quickly spread to other surface parts of painting so that service life of painting extends. - Good Suspension
Special treatment has been done at inner structure and surface structure of our silica matting agent so that lumps precipitation and stratification phenomenon won't appear even if it is placed for long time.
