A method of improving the flowability and reducing voids in liquid synthetic thermosetting resins precursor compositions used to pot structures such as a honeycomb core or electronic parts and assemblies. Up to about 0.50 weight percent of a suitable titanate coupling agent is mixed with the liquid resin precursor, preferably in a vacuum or an inert atmosphere, any necessary hardener is added later to the premixed resin with the agent, then the resin is poured into a mold holding the structure to be potted. The titanate coupling agents have the general formula: ##STR1## where: R is an alkoxy, alkyl, alkenyl, alkynyl or aralkyl group having from 1 to about 30 carbon atoms or a substituted derivative thereof;
