Definitions

  • the following example illustrates the preparation of a glycidyl polyether or epoxy resin suitable for use in preparing the track and arc-resistant epoxy coating composition.
  • the mixture was then permitted to separate into two layers, the upper layer was withdrawn and discarded and the lower layer was washed with boiling water to which was added acetic acid in an amount suflicient to neutralize unreacted caustic soda.
  • a liquid resinous reactive polymeric epoxide was obtained after substantially all of the wash water had been removed.
  • the liquid resinous polymeric epoxide or glycidyl ether thus obtained is suitable for use in formulating the track and arc-resistant epoxy composition.
  • Additional track and arc-resistant epoxy coating compositions may be prepared by varying the ratio of aluminum oxide trihydrate to the total amount of epoxy resin and cross-linking agent.
  • the aluminum oxide trihydrate exceeds 75%, by weight, of the composition, excluding the solvent, the cured composition will lack homogeneity as the resin content is not sufiicient to wet or coat and adequately bond all of the oxide particles.
  • Compositions including less than 25%, by weight, of aluminum oxide trihydrate, excluding the solvent do not possess the excellent arc and track resistant properties desired, although as little as 5%, by weight, of aluminum oxide trihydrate will produce some improvement in these properties over that of the resin alone.
