Brass and Copper Corrosion Resistant Coatings

Brass and copper alloys will oxidize and tarnish rapidly after being chemically polished.  Corrosion resistant coatings are used to maintain and prolong brightness.  Metalline Chemical Corporation manufactures the following environmentally friendly non-chrome tarnish inhibitors:

  • AP BRASS PROTECTOR is a liquid water shedding tarnish inhibitor for brass and copper alloys. AP BRASS PROTECTOR does not contain any chrome and is designed to prevent water spots and tarnishing after cleaning, bright dipping or plating brass and copper metals.  AP BRASS PROTECTOR should be the final chemical step prior to shipping or storage and will provide excellent short term protection.
  • BP-965 is a concentrated high protection water based corrosion inhibitor for both ferrous and non-ferrous metals. BP-965 does not contain any Nitrates, Amines, Phosphates or harmful chrome based components.  BP-965 is currently being used to prevent staining on nickel and silver plated deposits; to prevent rust from forming on machined steel in a spray applications; to prevent premature corrosion of pre-cleaned zinc die castings and to provide extended protection of brass plated musical instrument components.  BP-965 is also an excellent alternative to oil-based rust preventatives, providing a much cleaner option for preventing corrosion and oxidation during storage.
  • BP-900 is a high protection water based tarnish and corrosion inhibitor for brass, copper alloys and silver.  BP-900 is not a lacquer and is easily removed through immersion in most aqueous cleaners.  BP-900 does not contain any chrome and is designed to prevent water spots and tarnishing after cleaning, bright dipping or plating brass and copper metals.  BP-900 should be the final chemical step prior to shipping or storage and will provide excellent long term protection.
