METALLIC PIGMENTS WITH CORROSION-RESISTANT COATINGS

The invention relates to metallic pigments based on aluminum and/or alloys thereof and methods for their manufacture that have a nucleus/shell structure and additionally protection against corrosion, and a method of producing and of using pigments of such a structure. The technical result is to impr...

Beschreibung
Zusammenfassung:	The invention relates to metallic pigments based on aluminum and/or alloys thereof and methods for their manufacture that have a nucleus/shell structure and additionally protection against corrosion, and a method of producing and of using pigments of such a structure. The technical result is to improve the corrosion resistance of metallic pigments based on aluminum and alloys thereof when they are used in coatings for external application in strongly corrosive media; said result is achieved by applying a continuous transparent corrosion protection layer to the surface of the metallic pigment in an organic solvent medium with the use of specially selected organic salts and additives. Using coatings with a refractive index from 1.4 to 1.8 involves a technical solution to the problem of producing a metallic pigment and using it for matte coatings while maintaining a metallic sheen.
