Precipitated Silica HS Code: 281122 Paint Matting Agent as White
Powder Used For Industrial Coatings
Introductions
1) Matting Agent specialized used for the Industrial coatings. It
is synthetic amorphous silica appearing as white powder. It is a
micronized precipitated silica matting agent for both solvent-based
and water-based system.
2) Silica Matting Agent reduce the gloss of a variety of products
including coatings, paints, inks, lacquers, varnishes, while
providing lower viscosity and better flow capability.
Feature
1) High Matting Efficiency: High pore volume reaches to 1.8-2.0
ml/g, and fine control of the particle size and particle size
distribution.
2) Easy to Dispersion: The matting agent can be easily added in any
production procedure and can be easily dispersed, which saves the
processing time.
3)Good handing feeling and improvement in scratch resistance: It is
development of smooth films with excellent hand-feel, scratch
resistance and stain resistance.
