The Skinny on Prepainted Metal

摘要

Using prepainted metal is a solution for many manufacturers who use sheet metal that is fabricated into parts or products that are postpainted either for decorative or corrosion protection purposes. With this technology, large coils of metal sheet stock (including cold-rolled steel, hot dip galvanized, electro galvanized, zinc-steel, aluminum, stainless steel, copper, and brass) can be coated in a continuous, highly automated process prior to fabrication. During this continuous process, the metal coil is unwound, the top and bottom sides are cleaned, chemically treated, primed, ovencured, topcoated, oven-cured again, and then rewound for shipment. The variety of coatings available is almost unlimited and includes polyesters, polyurethanes, epoxies, vinyls, plastisols, acrylics, waterborne emulsions, zinc-rich coatings, fluoro-carbons, dry lubricants, and treatment and primer combinations.
