Zinc molybdate is a white non-toxic anti-rust paint, widely used primer, paint and lacquer combined ground, including water-based paint. 

 

Although pure zinc molybdate can be used as anti-rust paint to use, but the price is too high, it is difficult to promote the use. The pigment to market goods or basic zinc molybdate, zinc molybdate (ZnO · ZnMoO4) based, adding some calcium carbonate or precipitated barium sulfate, talc, silica, rust-preventive pigment made ​​of composite, called white molybdate pigment, wherein in addition to the main component, zinc molybdate, calcium molybdate may also contain, or strontium molybdate, generally contains 75% of the filler. Toxicity, safe, the primer can be made ​​white, the hiding power of the white paint can be reduced, thereby saving the amount of titanium dioxide manufactured by the use of white paint. In addition, it also has some hiding itself, can replace part of the hiding power of the pigment. Affordable alternative to lead, chromium containing toxic anti-rust paint, rather than high-impact paints costs. Sometimes, the role of anti-rust paint with phosphate complexes, for example,the proportion of molybdenum ions with phosphate ions to 7: 3 fit, get a good anti-corrosion effect.
