LOW VISCOSITY, ETHYLENICALLY UNSATURATED POLYURETHANES CONTAINING ALLOPHANATE GROUPS |
摘要 |
The present invention relates to ethylenically unsaturated polyurethanes which are substantially free from isocyanate groups and have a) a total content of (meth)acryloyl groups (calculated as C=C, MW 24) of 1 to 20% by weight. b) an allophanate group content (calculated as N2C2HO3, MW 101) of 1 to 20% by weight and c) an isocyanurate group content (calculated as N3,C3,O3, MW 126) of up to 18% by weight, in which the allophanate and isocyanurate groups are prepared from aliphatic polyisocyanates. The present invention also relates to a one-component coating composition containing these ethylenically unsaturated polyurethanes.</SDOAB >
