Provided are: an emulsion composition which can be easily cured at room temperature and is capable of achieving high water resistance, high acid resistance and high base resistance; and a surface treatment method which uses this emulsion composition. This emulsion composition is specifically an oil-in-water emulsion composition which contains 100 parts by mass of (A) a (meth)acrylate epoxy resin, 1-200 parts by mass of (B) a polymerizable unsaturated monomer, 0.1-10 parts by mass of (C) a curing accelerator, 1-50 parts by mass of (D) a reactive surfactant and 10-200 parts by mass of (E) water. This surface treatment method is specifically a surface treatment method for a metal, plastic, concrete, mortar, wood or glass, in which a coating liquid is prepared by adding (F) a curing agent into the above-described oil-in-water emulsion composition, and the coating liquid is applied to a metal surface and then cured at 0-50°C, thereby forming a cured coating film on the metal surface. |
