Abstract
An in-situ formed polyurethane catalyst for catalyzing the formation of polyurethane in a reactive composition comprising polyisocyanate compounds and isocyanate reactive compounds, said catalyst formed by combining in said reactive composition:
- At least one lithium halide compound, andAt least one epoxide compoundwherein the amount of epoxide to be used is such that the number of epoxide equivalents per isocyanate equivalents is from larger than 0 up to 0.095 and the number of moles of lithium halide per isocyanate equivalent ranging of from 0.0001-0.06.
