Sealers/Topcoats
Sealers, commonly known as Topcoats, are post-treatment coatings applied over zinc or zinc-alloy plating to dramatically enhance corrosion resistance. These sealers can add hundreds of hours to salt spray performance, while also controlling friction and offering attractive finishes in clear, yellow, or black. Modern solutions are eco-friendly and hexavalent chromium-free, aligning with stringent environmental standards.
