Excelguard 504 is a solvent deposited water displacing corrosion preventative. Excelguard 504 is a blend of dewatering agents, corrosion inhibitors, hydrocarbon mineral oils, synthetic sulphonates and hydrocarbon solvents. It offers medium to long term protection of ferrous and aluminium alloy components. It leaves a thick oily anti corrosion film when applied. It is ideally suited to inter-process protection after machining. Excelguard 504 is best applied by dipping, spraying or brushing. If a tank is being used the residual water should be drained off periodically. Allow up to 50 minutes drying time. It may affect some rubbers and plastics on long term exposure.
