The coated materials of the invention having improved corrosion and erosion resistance and improved low profile.
Claims33
A coating composition especially suitable for coatings which have improved surface profile, corrosion resistance, erosion resistance and which are capable of faster curing and becoming electrically conductive more rapidly, which coating composition comprises (a) and aqueous acid binder solution which comprises phosphate ions and ions selected from the group consisting of chromate and molybdate ions, and (b) a powder which comprises atomized aluminum spheroids having an average particle size (measured in ESD) not larger than about 4 microns.
A dry coating composition especially suitable for coatings which have improved surface profile, corrosion resistance, erosion resistance and which are capable of faster curing and becoming electrically conductive more rapidly, which coating composition comprises (a) a spray dried binder which comprises phosphate and an inorganic compound of the group consisting of chromate, molybdate and the metal salts thereof, and (b) a powder which comprises atomized aluminum spheroids having an average particle size (measured in ESD) not larger than about 4 microns.
A coating composition especially suitable for coatings which have improved low surface profile, smooth surface, improved corrosion and erosion resistance and which are capable of faster curing and becoming electrically conductive more rapidly, which coating composition comprises (a) an aqueous acid binder solution which comprises phosphate ions and ions selected from the group consisting of chromate or molybdate ions, and (b) a powder which comprises atomized aluminum spheroids of which at least about 52 weight percent and having an average particle size (measured in ESD) not larger than about 4 microns.
