Russian Polyurethane-1001 (RPU-1001)

Russian Polyurethane-1001 (RPU-1001) is an outer two-component polyurethane protective coating produced based on thermosetting materials.

The coating is designed for corrosion protection of pipes, junction pieces, shut-off valves and mounting components during construction, reconstruction or capital repairing of main gas pipelines and compressed-air plants with a temperature of the transported product below 40 º.
RPU-1011 is applied in consecutive stages on a pre-cleaned surface of a gas pipe section en route with a minimum ambient temperature of 5º.
