Epoxy coating system

A "hybrid" epoxy resin coating system formed by a solvent-borne epoxy resin and a water-reducible curing agent. The coating formed by this system exhibits excellent resistance to most household chemicals, and yet is permeable to water vapor transmission to reduce blistering. Although the epoxy resin is solvent-based, the total VOC content of the mixture is less than 150 grams per liter, providing a low odor mixture that is environmentally friendly. Additives in the curing agent component, including a silicone surfactant, provide a coating that adheres well even to a surface that is less than ideally prepared; no acid etching or other special surface preparation is required. All the colorant is on one side of the system, preferably in the resin component. Thus, incomplete mixing will not substantially affect the color of the finished coating. All these features make this coating system ideally suitable for use by nonprofessionals.
