FIELD: chemistry.
SUBSTANCE: invention relates to an enamel coating for coating the metal surface of an article. Disclosed is enamel coating material for coating the metal surface (5) of an article, which comprises a mixture of 5-50 vol % of catalytic enamel and 50-95 vol % of at least one of normal and pyrolytic enamel. Percentage composition of catalytic enamel and at least one of normal and pyrolytic enamel in said material is selected such that surface roughness according to average roughness coefficient (Ra) of the end enamel coating (7) ranges from 2 to 8 mcm and is suitable for further coating (8) by mechanical adhesion. Also disclosed are an article having a metal surface (5), at least partially coated with said enamel coating material, and a method of coating the metal surface of the article.
EFFECT: obtaining an enamel coating with surface roughness suitable for interaction by mechanical adhesion with a protective or easy-to-clean coating material or coating.
