摘要 |
In one embodiment, the invention is a composition comprising: a) one or more isocyanate functional polyether based prepolymers having a polydispersity of less than about 2.5 determined by Gel Permeation Chromatography at a Mp of >1000; b) one or more plasticizers in sufficient amount that the composition can be pumped and applied to a substrate at a temperature of −10° C., preferably in an amount of about 15 percent by weight or less; c) one or more fillers in sufficient amount such that the composition exhibits a press flow viscosity of about 8 grams per minute or more; d) one or more catalysts for the reaction of isocyanate moieties with isocyanate reactive groups; wherein the composition demonstrates 30 minutes after application a high speed impact of about 1.6 MPa or greater according to DIN EN 1465 high speed impact test. |
