USAGE

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.

 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.

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.

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.

 

1.1 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

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.

 

1.2 film artificial aging test

Put the different formulations of spray paint brush on the cement board, in the sunlight aging machine for artificial aging test. As a result, original production formula discoloration time for 580 hours, existing production formula discoloration time is 12 hours, after adding superfine barium sulfate the weather resistance of paint film can be significantly improved.

 

1.3 coating at room temperature results

Due to the small particle size of ultrafine barium sulfate, the agglomerated morphology also determines the density of not less than the general barium sulfate, so it overcomes the ordinary barium sulfate precipitation, easy lamination defects. The latex paint test samples placed a year without obvious stratification, settlement and the stability is good.

In addition, the film in the film in the water resistance, wet scrub, anti pollution, etc..

 

1.4 to 1 ~ 8 Lm barium sulfate shattering particle size, can replace part of titanium dioxide when applied in latex paint, whiteness And hiding power did not decline, although after smashing the barium sulfate is fine, but it is still on the agglomeration of the agglomeration of medium sized particles. Because of precipitated barium sulfate in formation, the crystal size is between 0.2 ~ 0.8 Lm, the agglomeration of particles clearance is too small, so that scattered resin could not enter into the agglomeration in the body, the results when the paint film after drying, these small air gap being preserved, in the form of air, thus improve the refraction between the various components. In this film, the material's refractive index is as follows: 2.76, titanium white polymer is 1.55, the water is 1.33, 1.0 air in the wet film And dry film, mainly from the following several refractive index difference determines the size of the covering power: titanium white - polymer = 2.76-1.55 = 1.55, titanium white - water = 2.76-1.33 = 1.33, titanium white - packing = 1.11, titanium white - air = 1.76. Thus it can be seen that as a result of the existence of ultrafine barium sulfate powder, after the coating film, in addition to other refractive index difference, And the difference of the titanium white And the water's refractive index. After film into a dry film, due to the evaporation, the micro air bubble in the paint film, And produced between titanium dioxide and air refractive index difference, objectively increased the scattering ability of titanium dioxide, thereby increasing the hiding power, so superfine barium sulfate can replace part of titanium dioxide, and hiding power is not decreased.
