ASTM Paint Committee Approves Powder Coating Standard

New ASTM International standard describes methods of preparing surfaces of hot-dip galvanized iron and steel for powder coating and the application of powder coating materials.

The new standard, ASTM D7803, Practice for Preparation of Zinc (Hot-Dip Galvanized) Coated Iron and Steel Product and Hardware Surfaces for Powder Coating, was developed by Subcommittee D01.46 on Industrial Protective Coatings, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.

“ASTM D7803 explains the steps to achieve adherence of powder coating over galvanized steel so there is no adhesion failure of the powder system,” says Thomas Langill, technical director, American Galvanizers Association, and an ASTM member. “There has been increased interest in powder coating since it has no volatile organic compounds over corrosion protection, such as galvanized coating for color and appearance.”

Langill notes that D01.46 is currently seeking powder coaters and inspectors to contribute to ongoing standards activities.
