Transportation and Storage Safety:
This product, non-toxic harmless, white powder, prevent moisture in the process of transportation, storage should be placed in a cool, ventilated, dry place. Avoid breathing dust when processing, if contamination, can be cleaned with soap and water , concrete technology may refer to the corresponding material safety data.
Powder coatings , difference forms with general coatings, as the micron powders existence. Because not use solvent, to be called powder coatings. The main features: Harmless, high efficiency, saving resources and environmental protection characteristics
Two categories: Thermoplastic Powder Coatings and thermosetting powder coatings.
Thermoplastic powder coatings is made up of thermoplastic resin, pigments, fillers, plasticizer and stabilizer and so on.
Thermoplastic powder coatings: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester.
Thermosetting powder coating is made of thermosetting resin, curing agent, pigments, fillers and additives, etc.Thermosetting powder coatings: epoxy, polyester, acrylic resin.
1. The main purpose of Barium sulfate precipitated is used in paints and coatings, the domestic paint industry has gained rapid development, the global paint coating increased by 3.9% in 2014, sales reached 43.38 million tons, the sales of architectural coatings is 21.69 million tons, 50% of the total industry sales, industrial paint sales of 12.5802 million tons, 29% of the total industry sales, Barium sulfate is one of the essential raw materials in coatings, used as filling material which can reduce the cost of coating production, and filled with precipitated barium sulfate, production performance is stable, can increase the hardness, wear resistance, sunlight resistance, can replace some parts of titanium dioxide.
high solid coatings
Excellent size distribution (0.7μm), can improve the gloss and reduce VOC and the cost of production.
The crystal structure makes it a good smoothing agent, and can enhance the flat in the coating.With a small oil absorption, high gloss, good covering power, good weather resistance, and low particle size, etc.
water based coatings
Due to the chemical inertness and solubility, it also use in water-based coating, especially in the electrophoresis paint.
Special inorganic processes, and other useful properties remain the same, and through the inorganic semiconductor, given the conductive properties via the coating.
Barium sulfate can make the pigment steady, prevent flocculation, wear, and has excellent weather resistance and transparency. Used to increase the solids metallic paint, and won't cause color changes;Can also influence or control the flow leveling of sheet metal.
