Expancote Zinc Galvanize is a high-performance, zinc-rich cold galvanizing coating designed to deliver advanced galvanic corrosion protection to all ferrous metals. Featuring a 90% dry-film zinc content by weight, it dries to a mid-grey, matt finish and can be used as a durable rust-inhibiting primer or a standalone protective finish. It prevents rust creep, dries in less than an hour, and is easily applied by brush or roller for structural steel, plant machinery, piping, and rebar.
