| 摘要 |
The invention relates to solid, adhesive materials which peel off smoothly and based on reaction products of polyisocyanates, the material containing moisture-reactive NCO groups and being anhydrous. The polyisocyanates are reacted directly or indirectly with monofunctional fatty derivatives which contain 8 to 22 C atoms. The functional groups are in particular COOH, OH, SH, NH2 and NHR1 groups, wherein R1 is an alkyl or aryl group with 1 to 30 C atoms. The materials according to the invention are characterised by high levels of strength, are easy to handle and are suitable for coating, sealing, filling and adhering. In particular, adhesive sticks can be produced from said materials.
