ISOCYANATES CONTAINING URETDIONE GROUPS |
摘要 |
The invention relates to novel compounds containing uretdion groups, a method for the production thereof by dimerization of aliphatic and/or cycloaliphatic isocyanates with exclusively secondary and/or tertiary bonded isocyanate groups and the use of uretdion polyisocyanates obtained according to said method from diisocyanates with exclusively secondary and/or tertiary bonded isocyanate groups as starting components for polyurethane plastics, especially as isocyanate components for the production of uretdion coating powder cross-linking agents.
