Process to prepare aqueous dispersions of epoxy resins |
摘要 |
A process to provide an aqueous dispersion is provided comprising the steps of: a) emulsifying a mixture comprising i) water, ii) at least one epoxy resin having a functionality of greater than 0.8 epoxide group per molecule, iii) from 0.1 to 20 weight percent, based on the epoxy resin, of at least one polyoxyalkylene surfactant, and iv) optionally an acetone-free solvent solution to produce a resin-surfactant emulsion; and b) adding a solvent mixture to said resin-surfactant emulsion, said solvent mixture comprising i) acetone and ii) a non-volatile hydrophobic liquid resin or resin modifier to produce the aqueous dispersion.
