Coating agent and method for producing same

摘要

A two-component coating composition comprising (I) a component comprising at least one isocyanate as crosslinking agent and (II) a component comprising at least one binder having functional groups which react with isocyanate groups. Component (I) comprises at least one isocyanate Ia) having at least one diisocyanate structural unit which has an unsaturated/aromatic or non-aromatic ring structure having 5-10 ring atoms and two isocyanate groups attached to the ring structure. Instead of this isocyanate Ia) or in addition thereto it is possible to use an oligomer Ib) of this isocyanate Ia) having from 2 to 10 isocyanate units, especially a trimer Ib) and/or partially blocked isocyanates Ia) and/or oligomers Ib)(=crosslinkers Ic).
