Abstract
Abstract An epoxy resin composition which comprises: (1) a monoepoxide having at least one perfluoroalkyl group in one molecule; and (2) an epoxy resin having two or more epoxy groups in one molecule, the weight ratio of (1):(2) being 0.05:99.95 to 50:50. The composition can be cured with a curing agent to give a cured product having improved water-proof, oil-resistance and anti-contamination properties.
