FIELD: chemistry.
SUBSTANCE: invention relates to protective coatings, a fastener and other surfaces coated with said coatings, for example, such coatings and fastener, which are capable of protecting one or both of two different metals connected together, from corrosion or damage, such as structural corrosion or decomposition. The corrosion-resistant coating composition includes inorganic salts and an alkaline salt of poly(3-ammonium propylalkoxy siloxane)carboxylic acid (PCAS) as a corrosion inhibitor, suspended in a residue containing a phenol-formaldehyde thermosetting resin. The coating material can be deposited on metal articles, but not limited to an aircraft fastener, such as aircraft fastening components, including nuts and bolts, screws and rivets.
EFFECT: coating does not contain chromate, but is as effective in preventing corrosion as coatings containing chromate.
