Can You Powder Coat Zinc?
Products made from zinc alloy provide a perfect surface for powder coating and form an excellent bond. Like other metals, zinc alloys gain the best results from powder coating that’s combined with professional surface preparation. Zinc die cast products have a release agent left on them from the foundry that must be removed mechanically prior to coating. To prepare zinc for powder coating, we recommend blasting, pretreatment and a coat of specialized primer paint for the best results. Effective surface preparation prevents outgassing, pinholes, problems with adhesion and other common issues.
