Abstract:
An organic solvent free process to make an aqueous co-dispersion of epoxy resins and at least phenolic novolac resins is reported. The compositions of such co-dispersions are based on blends of epoxy resins and at least a phenolic novolac resin within the profile viscosity versus temperature in the ranges from 1 500 000 to 300 mPas at 80° C. and 10 000 to 20 mPas at 120° C.
