Product Description
System Description
The MENG SHAN 980,955 is a multilayer system used for the protection of steel pipelines. MENG SHAN 1019,1027, Liquid Adhesives can be used as primers for this system.In addition to serving as primers, these liquid adhesives themselves represent an anticorrosion 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 MENG SHAN 980 is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer MENG SHAN 955,achieves a complete bond to the MENG SHAN 980 inner layer, providing maximum handling and in-service protection for the coating system. The adhesives in these and all MENG SHAN tape systems contain proven anti-microbial additives.The MENG SHAN 980/955 can also be used for ductile iron pipes, in this case the use of 1027 primer is recommended.
