Zusammenfassung:	An extruded metal profile is obtained by application of a mixture containing an organosilane composition and coating of the metal surface so treated with an extruded melt of a polyamide molding material followed by drying. An extruded metal profile is obtained by application of a mixture containing an organosilane composition and coating of the metal surface so treated with an extruded melt of a polyamide molding material, followed by drying. The mixture is prepared from: (a) Q mole of a functional group carrying alkoxysilane of formula (I): and (b) M mole of alkoxysilane selected from (alpha) trialkoxysilanes of formula (II): and or dialkoxysilanes of formula (III): and or alkoxy compounds of formula (IV): where A = a substituent directly or through an aliphatic or aromatic hydrocarbon residue bonded to an amino-, alkylamino-, dialkylamino, amido-, epoxy-, acryloxy-, methacryloxy, cyano, isocyanato, ureido, thiocyanato, mercapto, sulfan- or halogen group, R = methyl, ethyl, or A (as defined above), y = 0 or 1, R asterisk ,R asterisk asterisk , R asterisk asterisk asterisk , and R asterisk asterisk asterisk asterisk = 1-8C alkyl or a corresponding alkyl substituted by alkyl(polyethylene glycol), R ,R ,and R = alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl or aromatic group with a maximum of 18 C, or these groups partially fluorinated and/or substituted with alkoxy and/or aryloxy groups; Me = selected from Si (n = 4) or a metal, e.g. Ti (n = 4), Al (n = 3), and Zn (n = 2), with the proviso that M and Q are in molar ratio 0 ≤ M/Q ≤ 20. In mixtures of compounds I to IV, these compounds contain at least 2,4-alkoxy groups OR asterisk ,OR asterisk asterisk ,OR asterisk asterisk asterisk , or OR asterisk asterisk asterisk asterisk per Si or metal atom, and if one of the named metal compounds is used as the compound of formula IV, the metal/Si atomic ratio in the mixture of compounds I to IV is 4:6 at maximum. The treated and dried metal surface is coated with an extruded melt of a polyamide molding material. An Independent claim is included for preparation of an extrusion coated metal object by the steps (a) and (b) above where formulas I-IV and R asterisk -R asterisk asterisk asterisk asterisk , n, and y are as defined above.
