HS code 2833270000 Micronized Barium Sulfate Powder Industrial With High Affinity

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.

2. Technical Data (standard:Q/VAIP1-2010)

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

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.
