Bob,

McMaster Carr supplies a Teflon epoxy system which has a liquid etchant to prepare the surface for their two component epoxy. Its packaged in a circular cardboard box with a screw top lid.  We've used it to bond Teflon to aluminum for decades. Don't know if it works on epoxy/resin boards but as it can bind Teflon to Teflon (another app we have a requirement for) give them a call to see what they recommend.
