Coating material which is thermally curable and curable by means of actinic radiation and method for coating microporous surfaces
First Claim
1. A coating material curable thermally and with actinic radiation, comprising (a1) at least one constituent comprising (a11) on average per molecule at least two functional groups which contain at least one bond activatable with actinic radiation (a2) at least one thermally curable constituent comprising at least two isocyanate-reactive groups, and (a3) at least one aromatic polyisocyanate which is free from functional groups (a11).

Abstract
A coating material curable thermally and with actinic radiation and comprising (a1) at least one constituent containing (a11) on average per molecule at least two functional groups which contain at least one bond which can be activated with actinic radiation and which serves for crosslinking with actinic radiation and, if desired, (a12) at least one isocyanate-reactive group, (a2) at least one thermally curable constituent having at least two isocyanate-reactive groups, and (a3) at least one aromatic polyisocyanate which is free from functional groups (a11), or a mixture of at least one aromatic polyisocyanate which is free from functional groups (a11) and of at least one (cyclo)aliphatic polyisocyanate which is free from functional groups (a11); and its use for coating microporous surfaces, especially of SMCs and BMCs.
