摘要

A method for repairing a rigid and hollow article having therein a fluid permeable localized discontinuity, comprising: (a) spreading over said discontinuity a first epoxy resin coating composition comprising an epoxy resin having an epoxide equivalent between about 170 and about 250, and a curing agent, said epoxide mixture being capable of curing rapidly; (b) then applying on top of said first coating a second epoxy resin composition comprising an epoxy resin having an epoxide equivalent of between about 170 and about 250, and a curing agent, said second epoxy resin composition curing more slowly than said first epoxy resin composition.
