Compositions containing aromatic isocyanate functional components and aliphatic aromatics isocyanate functional components having improved cure speed

摘要

A composition comprising in Part 1: a) one or more isocyanate functional components having aromatic isocyanate functional groups; and b) one or more isocyanate functional components having aliphatic isocyanate functional groups; and in Part 2 c) one or more compounds having more than one isocyanate reactive groups: wherein the ratio of aromatic isocyanate functional groups to isocyanate reactive groups is from 0.95 to 1.05 and the ratio of aromatic isocyanate functional groups and aliphatic isocyanate functional groups (total isocyanate groups) to isocyanate reactive groups is from 1.10 to 1.30.
