<p>A seal coat for use in a traffic surface is formed by reacting a first component comprising a liquid epoxy resin and a blocked polyisocyanate prepolymer with a second component comprising an aliphatic or cycloaliphatic polyamine, and allowing the mixture to cure. Advantageous results are achieved if the mixture, before curing, is allowed to impregnate a matrix, e.g. a non-woven synthetic material.</p> |
