Chromium(III) Phosphate Tetrahydrate Powder Applications:

-Anti-corrosive Coating

Paints containing chromium(III) phosphate have been used as corrosion resistant coating for metals. The paints consist of aqueous acidic chromium (III) phosphate solution which convert to a consistent film when applied onto metals heavily used in manufacturing and utility such as zinc, zinc alloy, aluminum and aluminum alloy substrates. Application methods include electroplating, immersing or spraying the solution on the surface of the substrate.

 

-Catalyst

Chromium (III) phosphate has various applications in the polymer industry. Combined chromium(III) aluminum phosphate is widely used as a catalyst in the alkylation of aromatic hydrocarbons using alcohols such as the methylation of toluene using methanol. The alcohol is dehydrated into ether while the alkyl substituted product could be used as an intermediate in the manufacture of synthetic fibers such as poly(ethylene terephthalate).

 

-Polymer

Pretreatment with chromium (III) phosphate-silicate is also used as a laminated structure to dampen vibration and noise in a motor.

 

Chromium(III) Phosphate Tetrahydrate Powder Packaging:

Our Chromium(III) Phosphate Tetrahydrate Powder is stored in a cool, ventilated warehouse and will be kept sealed. It will be carefully handled during storage and transportation to preserve the quality of our product in its original condition. It will be packed in vacuum packing in carton or iron drum.
