PROCESS FOR APPLYING A COATING TO A COILED METAL SHEET

摘要

The invention relates to a process for preparing a coated metal sheet coil comprising the coating of the metal sheet with a curable composition comprising an (meth)acrylated oligomer which is the reaction product of a carboxyl functionalized polybutadiene comprising x equivalents of -COOH groups with (i) y equivalents of one or more (meth)acrylated monoepoxides or (ii) a mixture of z equivalents of one or more polyepoxides and at least (z - x) equivalents of an alpha, ß-unsaturated carboxylic acid ; with z > x and y >x.
