THIXOTROPIC POLYURETHANE COMPOSITIONS USEFUL AS SEALING AGENTS FOR MEMBRANE SEPARATION DEVICES |
| abstract |
The present invention relates to crosslinkable thixotropic polyurethane compositions. They comprise a, as a prepolymer, a reaction product of a polyol having a hydroxy functionality of at least 2 with 1 mole per hydroxy group of an organic diisocyanate, and b a crosslinking agent comprising a polyether polyol having a functionality. hydroxy of at least 2 and a polyether with a primary amine terminus having an amine functionality of at least 2. Application for sealing the edges of membrane separation devices, in particular artificial kidneys. |
