FERROZINC is a high performance water thinnable rust converter. It is an easily applied single pack material with excellent long term conversion properties. In many situations blast cleaning is not cost effective or practical, and though Ferrozinc is not an equivalent alternative to shot blasting, it does offer a far superior performance than conventional coatings applied to slightly rusted surfaces. FERROZINC is used after simple wire brushing to remove surface rust. A dramatic colour change from white to black will show that the rust has been effectively neutralised. FERROZINC should then be overcoated with a suitable primer & topcoat system for prolonged corrosion resistance. Salt spray and extended durability testing has proven FERROZINC to out-perform competitive rust conversion materials. For use on ferrous metals only. Not designed for use on non-ferrous metals (aluminium, copper, & stainless steel etc).
