Epoxy resins have been made water reducible by the use of acid functional acrylic resins. They find widespread application as internal lacquers for DWI beer and beverage cans (see Chapter 7- Waterborne Applications). They are often made in solution in butyl glycol and butanol and are then neutralised and dispersed into water under agitation. A full discussion of this technology and all of its variants is given in the Epoxy volume of this series of books. A brief outline of some of the chemistry will be given here.
