Corroless SHB is a high build, general purpose anticorrosive primer for hand-prepared steelwork, containing Corroless rust stabilising pigment. Corroless SHB can be applied to around twice the film thickness by brush compared to Corroless S, but does not have such a high operating temperature. Corroless SHB has a designated NATO stock number. Typical applications include mechanical equipment, tank exteriors, bridges and pipework.
