BaSO4 powder HS code 2833270000 natural Micronized barium sulfate
paint
1. Barium sulfate as an extender pigment is widely used in paint,
plays a very important role to improve the coating's thickness,
abrasion resistance, water resistance, heat resistance, surface
hardness, resistance to impact etc.. In addition, barium sulfate in
the wavelength range of 300~400Lm have very high reflective, can
protect the film from photoaging, is an effective and inexpensive
inorganic white light stabilizer.
Using special technology is made of super fine barium sulfate has
many other similar products do not have the characteristics. The
acicular crystal structure make it become good flatting agent, and
can enhance the coating leveling. It can be used for self clean
coatings were used as reinforcing agent; due to the low amount of
the oil suction, high filler content, so can decrease the cost of
coating can be used for water paint, primer, intermediate coat, oil
paint. Use it to replace the water paint in 10% ~ 25% of titanium
dioxide. The results improve the whiteness, hiding power did not
decline.

Applications:
1. paint, paint production of barium sulfate characteristics
requirements
Powder Coatings: High whiteness, easy dispersion, black spots, and resin have good
affinity, improve the powder rate, can significantly improve the
surface gloss, leveling, hardness, impact resistance, adhesion.
anticorrosive paint: Stable chemical stability, good dispersion, oil absorption, with
the space effect, reduce the amount of pigment.
Plastics paints: Super fine grain size and grain size distribution, good dispersion
and anti sink, add a small amount of plastic paint, increase the
film hardness, add paint does not affect the gloss, color density,
brightness, effectively reducing the use of resin and pigment,
unable to add traditional packing of high-grade paint add add the
product has excellent effect.
Paper paints : Introduced in can increase the gloss, liquidity, such as art paper
in white and transparent colored paper. Part of titanium dioxide
available double barium sulfate instead of without losing its
luster.
Emulsion coatings: Good particle size distribution, good dispersion and anti sink,
adding high gloss latex paint does not affect the gloss, color
concentration, bright degree.
2. comparison of film whiteness and hiding power
The production formula (with superfine barium sulfate instead of
15% titanium dioxide) and the original production formula under the
same conditions of the plate test data as shown in Table 1
Effect of barium sulfate on the whiteness of coatings
Samples | Covering power g/㎡ | whiteness | Whiteness index |
Original | 138.5 | 87.89 | 79.8 |
Present | 129 | 87 | 80 |
From the table 1, we can see that the addition of ultra-fine barium
sulfate coating, the hiding power but increased, the basic
unchanged whiteness.
Because professional, so we do better!
we aspires to be the world's leading chemical raw materials supply
service, the value of that made in China should have!
