Continuous process for coating steel wire cord

A process for continuously coating steel wire said process comprising:

• wetting steel wire in an aqueous solution comprising at least 95% water and 0.01 to 5% weight/weight of the carboxylic acid salt of an alkoxy modified silsesquioxane meeting the following formula (I) to form a wet coated steel wire
• wherein w, x, y and z represent mole fractions, z does not equal zero, at least one of w, x or y must also be present and w+x+y+z=1.00;
• wherein at least one of R1, R2, R3 and R4 must be present and selected from the group consisting of R6Z, wherein Z is selected from the group consisting of NH2, HNR7, HNR7NH2 and NR72 and the remaining R1, R2, R3 and R4 are the same or different and selected from the group consisting of (i) H or an alkyl group having one to about 20 carbon atoms, (ii) cycloalkyl groups having 3 to about 20 carbon atoms, (iii) alkylaryl groups having 7 to about 20 carbon atoms, (iv) R6X, wherein X is selected from the group consisting of Cl, Br, SH, SaW, NR72, OR7, CO2H, SCOR7, CO2R7, OH, olefins, epoxides, amino groups, vinyl groups, acrylates and methacrylates, wherein a=1 to about 8, and (v) R6YR8X, wherein Y is selected from the group consisting of O, S, NH and NR7;
• wherein R6 and R8 are selected from the group consisting of alkylene groups having one to about 20 carbon atoms, cycloalkylene groups having 3 to about 20 carbon atoms, and a single bond;
• and R5 and R7 are selected from the group consisting of alkyl groups having one to about 20 carbon atoms, cycloalkyl groups having 3 to about 20 carbon atoms and alkylaryl groups having 7 to about 20 carbon atoms;
• evaporating water from the wet coated steel wire to form a mostly-dry coated steel wire;
• and
• in one or more steps heating the mostly-dry coated steel wire at a temperature between 50 and 240° C., such that the steel wire reaches a minimum temperature of at least 110° C. in at least one step, thereby forming a dry coated steel wire with a coating of thickness between 5 and 3000 nm.
