PROCESS FOR THE PREPARATION OF POLYADDITION PRODUCTS CONTAINING URETDIONE GROUPS AND THEIR USE IN POLYURETHANE COATING SYSTEMS |
摘要 |
The invention relates to a process for the preparation of polyaddition products containing uretdione groups, prepared from a polyisocyanate-uretdione having at least two free isocyanate groups, diols and, if desired, monoalcohols or monoamines, in which the polyaddition products containing uretdione groups are prepared by a solvent-free and continuous procedure which is carried out in an intensive kneading apparatus/extruder. The invention also relates to the use of polyaddition products containing uretdione groups for PUR powder coatings and for solvent-containing, one-component stoving enamels.
