A repair kit for the Forpol-Nafta coating: a two-component polyurethane mastic with 100 % solids that is applied by brush, roller or spatula. It is used to restore the external coating of pipes, fittings and shut-off valves of gas pipelines both in the factory and in the field, without expensive equipment. The pot life of the mix is more than 45 min, the compound dries to degree 3 in less than 6 h at 20 °C, and adhesion to steel is more than 7 MPa.
