| 摘要 |
The aim of the invention is to provide a method for producing polyurethane elastomers which correspond to heat-hardened elastomers in terms of quality and have an extended pot life, on the basis of TDI- and/or MDI prepolymers and MCDEA (4,4'-methylen-bis-(3-chloro-2,6-diethylenanilin)). To this end, the MCDEA has an average grain size of 30 mym and the method is carried out at room temperatures. |
