78 DUROX rust converter

DUROX is a highly effective rust stabilizer based on tannic acid for pretreatment of rusted metal surfaces. DUROX rust converter forms highly effective, bluish coloured iron complex salts with the rust and the metal base, which lead to a compaction of the metal surface. This largely prevents water and atmospheric oxygen from entering and thus slows down further rusting. By adding rust inhibitors, which additionally passivate the metal, as well as film formers, which strengthen the temporary protection, DUROX forms an adhesion bridge for a subsequent coating build-up. DUROX can also be applied at low temperatures and can be painted on still wet iron.
