Product introduction
A crystalline powder of barium borate, a white tronic system. It is known that barium borate has four kinds of water, one water, two water, four water, five water.
Compound, slightly soluble in water, easily soluble in hydrochloric acid. As a white functional pigment. It can enhance the anti mildew, rust, fire, powder and other properties of the coating. The primer and topcoat used in the coating industry are a new type of antirust pigment and also used in ceramics, paper making, rubber and plastics industries.


Basic performance
Barium borate molecular formula Ba (B02) 2 or BaO. B203 with a molecular weight of 222.95. White trapezoid crystalline powder with a relative density of 3.25 to 3.35.  The melting point is 1060 degrees centigrade. It can contain 2, 4 and 5 crystalline water. Soluble in acid and slightly soluble in water. It has the characteristics of fire protection, high temperature resistance, antirust, mildew proof and so on. Non-toxic

application
As an additive flame retardant for adhesives and sealants, it is suitable for epoxy resin, unsaturated polyester resin, phenolic resin, polyvinyl acetate, acrylic resin, polyamine ester, polyvinyl chloride and so on.
1. Antirust: barium borate has been used as an inhibitor for corrosion on the surface of steel. The antirust effect of barium borate is mainly due to
It is caused by the micro solubility and its alkalinity. Barium borate is a kind of weak acid strong alkali and the salt of silica coating. Although its solubility is minimal
But it is alkaline after hydrolysis.
2, antimould function: calcium metaborate is a long-term control of mold growth, the fungus can not breed efficient fungicide. This is due to the release of barium from calcium borate.
Sub and boric acid ions, in which barium ions interfere with soluble nutrients through microporous membranes, and prevent the reproduction of enzymes.
3. The anti powdery effect of the paint is eroded by the bacteria, the destruction of ultraviolet rays and the effect of wet gas, which destroys the powder of the paint film.  Barium borate is a paints
The effective anti powdery agent in the industry is in direct proportion to the amount of powder in the paint.
4, flame retardancy. In the plastic flame retardant system, it can replace three oxidation of two antimony and reduce the cost.
