Corroless QDR is a very fast drying, general purpose anticorrosive primer for hand-prepared steelwork, containing Corroless rust stabilising pigment. It also contains self-leafing glass flake for improved impermeability and abrasion resistance. Overcoating times typically start at only 30 minutes, enabling a rapid build-up of a repair system in a very short time, for situations where fast turn-round times preclude normal overcoating intervals. Corroless QDR has a designated NATO stock number. Typical applications include bridges, pipework, mechanical equipment and general steelwork.
