Procedure
To this inhibited epoxy diester-styrene mixture 5.49 parts of NADIC methyl anhydride and 0.048 part of 2,5-dimethyl-2,5 bis(benzoyl peroxy) hexane catalyst (sold by Wallace & Tiernan Inc. under the trade name of Luperox 118) were added, at 25° C., to provide the solventless epoxy-styrene impregnating varnish. The catalyst used has a catalytic reaction "kick off" temperature of about 115° C., i.e., it will have a definite catalytic effect to initiate a cure reaction at over about 115° C. The viscosity of the epoxy-styrene impregnating varnish was measured to be about 10 cps to 15 cps at 25° C. To this resin system 0.029 part of various metal acetylacetonates were added. One sample, containing no metal acetylacetonate was used as a control. The weight ratio of epoxy mixture: styrene: metal acetylacetonate was 1:1.9:0.0029. This varnish was prepared in 1 gallon laboratory batches and in 250 gallon large scale commercial batches.
