Abstract

A method and process for treating wood. The steps include preparing isocyanate-based reactive prepolymer resins for impregnation, impregnating wood with these impregnation resins, curing the impregnated wood at elevated temperatures, preparing isocyanate resin-based coating materials and applying these coating materials on the cured impregnated wood and curing the coatings at room or elevated temperatures. The resulting treated wood has substantially improved de-contaminability of the chemical warfare agent VX both initially and after long exposure to degradation effects from sunlight.
