Product
Description ：The special silica powder for coatings and
paints is a kind of inorganic non-metallic mineral functional
powder material, which is made of natural quartz ore and fused
quartz by fine processing such as color separation, magnetic
separation, grinding and precision classification. It has fine
particles, no large particles, good suspension, narrow particle
size distribution, large specific surface area and good
anti-sedimentation performance. It also has some characteristics of reinforcing
effect, acid and alkali corrosion resistance, poor thermal
conductivity, high insulation, low expansion and high purity. acid
and alkali corrosion resistance, poor thermal conductivity, high
insulation, low expansion and high purity. The addition of silica
powder in high temperature resistant coatings (ceramic coatings)
can not only increase the compatibility of filling, but also
improve the film hardness, enhance the anti-scratch, anti-corrosion
and anti-polishing properties of coatings. It also has auxiliary
extinction properties. Silica powder for coatings and paints can
improve fineness, leveling performance and film hardness, shorten
grinding time, water resistance, rust resistance, corrosion
resistance, dispersibility of pigments and storage stability of
paints. Application:
It is widely used in decorative
coatings, anticorrosive coatings, conductive coatings, rust-proof
coatings, high-temperature resistant coatings,
temperature-indicating coatings, heat-insulating coatings,
fire-proof coatings, waterproof coatings, etc., as well as interior
wall coatings, exterior wall coatings, wood coatings, metal
coatings, floor coatings, automobile paints,
etc.Main features:
1. Fine
particle size, no large particle size, high purity, good whiteness
and uniform particle size distribution. 2, low ion content,
low conductivity, excellent electrical insulation.
3.
Stable chemical properties, no reaction with any other substances
except hydrofluoric acid and strong base.
4, good
suspension, good settlement resistance. 5, acid and alkali
resistance, high temperature resistance, good insulation
performance. 6, high wear resistance, improve the resistance
to scratch coating. Â Â Â Â Â Â Â
