Zinc phosphate is formed from zinc phosphate cement and used in dentistry. Zinc phosphate dental cement is one of the oldest and widely used cements, and is commonly used for luting permanent metal and zirconium dioxide restorations and as a base for dental restorations. Zinc phosphate cement is used for cementation of inlays, crowns, bridges, and orthodontic appliances and occasionally as a temporary restoration. It is prepared by mixing zinc oxide and magnesium oxide powders with a liquid consisting principally of phosphoric acid, water, and buffers. It is the standard cement to measure against. It has the longest track record of use in dentistry. It is still commonly used; however, resin-modified glass ionomer cements are more convenient and stronger when used in a dental setting.
CORROSION RESISTANCE
The Pigment also physically prevents passage of water and salts. Thus the corrosion resistance is a major characteristic of Zinc Phosphate.
Good brushing characteristics can be obtained with Zinc Phosphate Primers, which are suitable for both airless and conventional spray application. None of these methods entails a health hazard.
Preservative Zinc phosphate
Nonvolatile white powder with very fine crystal,insoluble in water, nontoxic,nonirritant on skin, thermal stable.
When a quantity of zinc phosphate powder contact with the skin, that will block the sebaceous duct.
