EPOXY RESIN ADVANCEMENT USING URETHANE POLYOLS

摘要

EPOXY RESIN ADVANCEMENT USING URETHANE POLYOLS An ungelled reaction product of a polyepoxide and an active hydrogen-containing material containing at least two active hydrogens per molecule is disclosed. The active hydrogen-containing material being a hydroxyalkyl-substituted urethane in which the hydroxy group is in the beta position to the urethane group. The reaction product is useful as a precursor in making cationic resins for use in cationic electrodeposition.
