System Description
The polyken butyl tape / POLYKEN 955 is a multilayer system used for the protection of steel pipelines. POLYKEN 1019,1027, Liquid Adhesives can be used as primers for this system.In addition to serving as primers, these liquidadhesives 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 POLYKEN 980 is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer POLYKEN 955,achieves a complete bond to the POLYKEN 980 inner layer, providing maximum handling and in-service protection for the coating system. The adhesives in these and all POLYKEN tape systems contain proven anti-microbial additives.The POLYKEN 980/955 can also be used for ductile iron pipes, in this case the use of 1027 primer is recommended.
Uses and General Characteristics
Mechanical protection coating layer designed for 0.76 mm 30 mil 33 N/10 mm 300 oz/in 85 C 185 F
machine application.
Polyethylene anti corrosion adhesive tape can be used extensively in metal pipes of all pipelines and facilities in petroleum, natural gas, petrochemical industry, electric power, metallurgy, urban gas pipeline network and water supply etc. For efficient and long lasting outer anti corrosion.
Features
-Resistant to soil stress - Excellent adhesion to pipe and self -Low cathodic protection -Long-term in-ground performance - Serve for low-high temperatures |
- Cold applied -Uniform coating thickness -Compatible with all pipe diameters and generic plant coating systems -Qualified ASTM D1000,AWWA C 214,EN 12068 standards |
feature:
The tube is made of polyethylene and gauze fibers. Coated with high viscosity synthetic rubber, with a strong peel force, tensile, oil resistance, aging resistance, temperature, water, corrosion, is a high adhesion tape.
use:
Pipeline tape is mainly used for carton sealing, carpet seams, heavy packaging, waterproof packaging. At present in the automotive industry, paper industry, mechanical and electrical industry is also often used in car cab, chassis, cabinets and other better waterproof measures. Easy to die.
Transport and storage:
Semi-finished goods handling, storage should be placed on the shelves, and to avoid squeezing the plastic surface phenomenon
The product should be stored in the original packaging and stored in a cool, dry environment to avoid daylight, frozen or high temperature
- temperature 20 ℃ -30 ℃, humidity 50-70, shelf life of 12 months
