PRIMING METHOD AND PRIMER FOR ALUMINUM MATERIAL

摘要

PURPOSE: A priming method and a primer for aluminum substance are provided to accomplish an improved corrosion resistance by depositing a primer onto a surface of the aluminum material such as aluminum or aluminum alloy. CONSTITUTION: A priming method comprises the steps of depositing a primer containing 30 to 500g/l of a nitrate compound of metal selected from a group consisting of an aluminum, zirconium, cerium, chrome and iron onto a surface of an aluminum substance so as to thereby allow an amount of metal deposition to become 1.0millimole/m2 or higher, and performing a baking treatment onto the primer deposition.
