Abstract:
1. A process for making an autodepositing epoxy-based dispersion, the process comprising the steps of: (a) dissolving and/or reducing an epoxy pre-polymer with at least one ethylenically unsaturated monomer to form a mixture wherein the at least one ethylenically unsaturated monomer is an anionic functional monomer; (b) dispersing the mixture of step (a) in water with at least one surfactant to form a fine particle dispersion; and (c) polymerizing the at least one ethylenically unsaturated monomer contained in the fine particle dispersion to form an epoxy dispersion, wherein at least one water soluble initiator and/or at least one organic soluble initiator is added prior to step (c) and wherein at least one latent curing agent is incorporated into the mixture before the at least one ethylenically unsaturated monomer is polymerized.
