A brush applied, single component thixotropic coal tar mastic that provides corrosion protection for metal fittings, flanges, valves, tanks, mechanical couplings, anode connections and other irregular configurations. Also, will protect concrete substrates and has good resistance to oil and gas. Royston Glas-Wrap can be used to offer additional strength and impact resistance.
