摘要： A method of using an epoxy resin composition is described comprising providing a substrate comprising a first hydrocarbon on a surface of the substrate; providing an epoxy resin composition on the surface of the substrate; and curing the epoxy resin composition. The epoxy resin composition comprises i) an epoxy resin; ii) an epoxy resin curative; and iii) a second hydrocarbon. The first and second hydrocarbons are typically a liquid or semi-solid. Suitable hydrocarbons include (e.g. anticorrosion) oil, petrolatum, and polybutene. Also described are one and two-part compositions comprising an epoxy resin; an epoxy resin curative; and a hydrocarbon as described herein.
