GalMax™ 93 Cold Galvanising Paint is a weld through zinc-rich coating containing 93% zinc in dry film which protects clean steel in the same manner as hot dip galvanising, ie, by cathodic reaction. It passes the tough ASTM B117-07, 168 hour salt spray test with no defects , and gives exceptional long term protection against rust and corrosion, weathering to the same colour as normal galvanising. With 99% zinc purity, GalMax™ 93 is ideally suited for touch-up welds and damaged structures or components, and is supplied to a wide range of industries from marine to construction. It is commonly used on marine and offshore rigs, during metal fabrication ,for hot-dip gal repairs, and to rust proof bridges, cooling towers, fencing, piping, and metal roofing.
