Abstract
A highly fluid, solventless, resinous, impregnating and coating composition, suitable as a high voltage insulation for electrical members, is made from an admixture containing: 100 parts of an epoxy resin, about 25 to 200 parts of an acid anhydride reactive with the epoxy resin, and about 0.002 to 1.00 part of a selected metal acetylacetonate, acting as a latent accelerator.
