PRODUCT DESCRIPTION:


Barium Sulfate used possesses yellowing resistant, good flow properties and lower oil absorption, a good choice of filler used in middle-grade and high-grade emulsion paint, which is known as acid-resistant emulsion paint. Even when products are exposed outdoor, they still resistant to acid. The good dispersity, good flow properties and gloss retention of Barium Sulfate improve the chemical properties of products.


APPLICATIONS:


      



ADVANTAGES:


Paint: In the paint industry, barite sulfate use as the filler and increase film thickness, strength and durability. Barite for paint industry requires sufficient fineness and high whiteness. It has high whiteness and dirt pick-up resistance. Increasing coating color solids when the specific gravity of Barium Sulfate is higher.


1. Lacquer and thick slurry coating

The high filling properties of Barium Sulfate can be applied to all coating series, such as all types of primer, thick slurry coating, etc., with low surface area and particle size division and mobility, which make barite powder with low wear resistance during processing. Barium sulfate is recommended for automatic primer surface layer, even when high filling is also maintained. Good uniformity and smoothness.


2. Surface Finish 

Barium Sulfate is superior to most other filler, especially in chemical resistant coating. Its inertness, insoluble in water, acid, alkali and organic intermediation. Excellent gloss and fineness of particles enable the topcoat to be protected during long-term exposure. Barium Sulfate is recommended for topcoat, which can increase surface hardness, color and stability.


3. Emulsion Paint 

Barium Sulfate can only be used for latex paint because of its weight. It is mainly used for high gloss and silk varnish, and has the title of "acid resistant" emulsion paint. It has acid resistance even when exposed. The dispersibility of Barium Sulfate, its optically active and easy retention can increase its chemical properties. Barium Sulfate can be used for high gloss and latex paints.
