Use of an isocyanate group-containing copolymer for moisture-curing surface coatings (paints)

The invention relates to the use of an isocyanate group-containing copolymer of from 5 to 60% by weight of an N-(1-alkenyl) isocyanate and from 95 to 40% by weight of at least one (meth)acrylate, some of which may be replaced by further copolymerisable, olefinically unsaturated compounds containing...

Beschreibung
Zusammenfassung:	The invention relates to the use of an isocyanate group-containing copolymer of from 5 to 60% by weight of an N-(1-alkenyl) isocyanate and from 95 to 40% by weight of at least one (meth)acrylate, some of which may be replaced by further copolymerisable, olefinically unsaturated compounds containing no OH-, CH-, NH- or SH-acidic groups, the copolymer having a mean molecular weight of from 500 to 10000, in combination with water as a binder for polyurethane paints, in particular for automotive refinish paints.
