Standard Specification for Zinc Phosphate Pigments

Summary

1.1 This specification covers three types of pigments commercially known as zinc phosphate each of which may or may not be available in specific grades delineated by particle size or oil absorption.

1.1.1 Type I—Zinc Phosphate, dihydrate predominant.

1.1.2 Type II—Zinc Phosphate, dihydrate tetrahydrate mixture.

1.1.3 Type III—Zinc Phosphate, tetrahydrate predominant.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.


Rationale:

This specification covers three types of pigments commercially known as zinc phosphate each of which may or may not be available in specific grades delineated by particle size or oil absorption. The following types of pigments are: Type I which is zinc phosphate, dihydrate predominant, Type II which is zinc phosphate, dihydrate tetrahydrate mixture, and Type III which is zinc phosphate, tetrahydrate predominant. Zinc phosphate functions as both a chemical and a pigment. As a pigment it is used in a variety of applications including that of corrosion inhibiting paints. The pigments shall be subjected to the following tests: specific gravity test, oil absorption test, Hegman grind test, coarse particles test, pH test, specific resistance test, moisture test, and loss on ignition test.
