Abstract:
1. A two-part composition comprising: A) in one part (i) one or more isocyanate functional prepolymers; and B) in a second part (ii) one or more compounds having isocyanate reactive groups; (iii) one or more fillers selected such that the composition is nonconductive; and (iv) one or more catalysts for the reaction of isocyanate groups with isocyanate reactive compounds: wherein either or both of the one or more isocyanate functional prepolymers and the one or more compounds having isocyanate reactive groups have solid organic particles grafted thereto such that the composition contains from about 6 to about 13 percent by weight of the total composition of the solid organic particles; wherein the composition after contacting the two parts exhibits a lap shear strength after 2 hours of 2.0 MPa or greater and an open time of about 15 minutes to about 30 minutes.
