Abstract:
1. A coated metallic substrate comprising a compound between the coating and the substrate, wherein at least 40% by weight of the compound consists of a polypeptide as an adhesion promoter between the coating and the substrate, wherein the polypeptide is a hydrophobin of the formula wherein each amino acid residue of each X independently is a naturally occurring amino acid Phe, Leu, Ser, Tyr, Cys, Trp, Pro, His, Gln, Arg, Ile, Met, Thr, Asn, Lys, Val, Ala, Asp, Glu, Gly; each numerical subscript designates the number of amino acid residues of its adjacent X; subscripts n and m independently designate the number of amino acids from 0 to 500, inclusive, of its adjacent X; and each C independently is Cys, Ala, Ser, Gly, Met or Thr, provided that at least seven of the C residues are Cys, wherein said polypeptide has a property in increasing the contact angle of a water drop on a glass surface coated with said polypeptide by at least 20° as compared to the contact angle of a water drop of similar size on an uncoated glass surface as measured at room temperature, and wherein the substrate comprises steel, steel coated with zinc, zinc alloys, aluminum or aluminum alloys.
