Corroless M allows a single anticorrosive primer to be used across different metal substrates, without the need for a separate etch primer. It can be applied directly to weathered galvanising as a patch or overall coat, and can also be applied to hand-prepared steelwork. Corroless M contains Corroless rust stabilising pigment and has excellent adhesion properties and flexibility for improved performance. Typical applications include street furniture, general structural steelwork, pipework and tank externals.
