Zinc Chromate Primer is a compound which physically appears as a yellowish green colour solvent which is added with a pigment and number of additives. It is widely used in industrial painting as a protective coating over materials like iron or aluminium to act as a corrosion-resistant agent and ensures a longer service life to the machine and automotive components. Zinc Chromate Prime has a chemical formula of ZnCrO4 and a molar mass approximately equals to 181.403 grams per mol. It has a density of 3.43 grams per cubic centimetre and is insoluble in water.
