How does AquaArmor compare to E-coat and other Coatings?
AquaArmor utilizes Autodeposition and provides a tight chemical bond to any steel, ductile iron, or grey iron part. Underbond corrosion and elimination of creep is typical with AquaArmor. Electrodeposition or Electro coat (E-coat) uses electrical current to coat a part. Faraday cage effect can have lightly exposed areas and limit coating in recessed voids. AquaArmor coats where the coating touches. E-coat has been driven down to a commodity status by the automotive companies. Companies have little differentiation on performance or specifiability. MetaKote and Crown are the largest E-coat houses. Most others are small regional facilities. The industry today has excess capacity which keeps prices fairly low. E-coat has been used heavily in the automotive, appliance and furniture business. • Does an AquaArmor coated part protected up against dissimilar metals. (Galvanic Corrosion). Yes! AquaArmor has excellent barrier properties when tested in compliance to ASTM G147 galvanic corrosion te
