409 Zinc Phosphate
Product Name: 409 Zinc Phosphate
Color Index Number: CAS【7779-90-0】；P.W.32
Molecular Formula: Zn3(PO4)2·2H2O
Product properties:
Colorless rhombohedral crystals or white microcrystalline powders. Low refractive index and high transparency. Soluble in inorganic acids, acetic acid, ammonia water, ammonium salt solutions, insoluble in ethanol; Water is almost insoluble, and its solvent heat decreases with increasing temperature. When heated to 100 ℃, two crystalline waters are retained, and at around 250 ℃, the crystalline water is lost and becomes anhydrous. Has deliquescence and corrosiveness.
Application Scope:
Zinc phosphate is a new type of non-toxic anti rust pigment. Used as a base material for various coatings such as alkyd, phenolic, and epoxy resins, as well as for the production of non-toxic anti rust pigments and water-soluble coatings. It is also used as a flame retardant for chlorinated rubber and synthetic polymer materials, and can also be used as a dental impression material.
Precautions:
This product should not be mixed with acidic, alkaline, or reducing substances.To prevent efflorescence during transportation and storage, store in a dry place and avoid extreme temperature fluctuations.Prior to use, conduct tests to ensure the product meets your company's requirements.
