摘要： An epoxy resin formulation is disclosed. Such a formulation is suitable for the use as coil insulation material, wherein the formulation includes (a) a purified grade of at least one diglycidyl ether of a bisphenol compound or at least one cycloaliphatic diglycidyl ether compound or a mixture of such compounds, wherein the compounds have an epoxy equivalent weight not exceeding 10% of the minimum epoxy equivalent weight calculated for each compound; and (b) the formation optionally includes up to 50% by weight of a diglycidyl ether of a bisphenol compound or of a cycloaliphatic diglycidyl ether compound or a novolac epoxy or a mixture of such compounds, wherein the compounds have an epoxy equivalent weight exceeding 10% of the minimum epoxy equivalent weight calculated for each compound; and (c) a polymerization catalyst.
