摘要 |
Isocyanate compositions with isocyanate functionality between 2.2 and 2.9 which include: a) 20 to 80% by weight of the reaction product of methylene diphenyl isocyanate (MDI) with an ethylene oxide (EO)/propylene oxide (PO) polyether polyol of functionality 2 to 8, an average molecular weight of 200 to 6000, and an ethylene oxide content of 20 to 90% having a free NCO group content of 26 to 33% by weight; and 20 to 80% by weight of an MDI polymer.</ SDOAB>
