LIQUID MDI ADDUCTS WITH IMPROVED FREEZE STABILITY

摘要

This invention relates to liquid polyisocyanate compositions having improved freeze stability. These liquid polyisocyanate compositions have an NCO group content of 15 to 30%, and comprise (A) an allophanate- modified MDI and having an NCO group content of 16 to 32.5%, (B) a low molecular weight branched aliphatic dihydroxy compound, and (C) an epoxide functional compound which is present in an amount of 0.01 to 1 by weight, based on the combined weight of components (A) and (B).
