The TSD 980,955 is a multi-layer system used for the protection of steel pipelines. TSD 1019, 1027, Liquid Adhesives can be used as primers for this system.In addition to serving as primers, these liquid adhesives themselves represent an anti-corrosion layer and provide a uniformly smooth contact surface to promote high adhesion of the coating system to the pipe. They are designed for machine or brush application and formulated with stress-corrosion cracking inhibitors. The Anti-Corrosion layer TSD 980 is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer TSD 955,achieves a complete bond to the TSD 980 inner layer, providing maximum handling and in-service protection for the coating system. The adhesives in these and all TSD tape systems contain proven anti-microbial additives.The TSD 980/955 can also be used for ductile iron pipes, in this case the use of 1027 primer is recommended.
