Abstract
PURPOSE: The title resin composition usefle for the insulation of electrical apparatus, having improved electrical characteristics, moisture resistance, and low viscosity, consisting of a bisphenol F diglycidyl ether type epoxy resin and an dibasic acid anhydride liquid at normal temperatures.
CONSTITUTION: A) A bisphenol F diglycidyl ether type epoxy resin having a chemical structure shown by the formula, an epoxy equivalent of about 170W190, and a viscosity at 25°C of about 30W40 poise is blended with B) a dibasic acid anhydride being liquid at normal temperatures, e.g, a mixture of 3-methyltetrahydrophthalic anhydride and 4-methyltetrahydrophthalic anhydride, a mixture of 3- methyl-2,5-endomethylene-1,6-dihydrophthalic anhydride and 4-methyl-2,5-endomethylene-1,6-dihydrophthalic anhydride, in the ratio of the acid anhydride equivalent of B) component to the epoxy equivalent of A) component of 0.8W1.1 to give the desired resin composition.
