This product has excellent water resistance and oxidation resistance.
1. The butyl rubber in the adhesive tape layer has excellent anti-oxidationfunction.
2. The products anti-corrosion system is composed of the inner layer of corrosion-resistant and the outside of the mechanical collision-resistant protective layer, whicht is not only a good anti-corrosion, and excellent resistance of the collision, and different from other anti-corrosion coat completely .
3. Winded under construction, the thickness and the width of the product is uniform ,which will prevent wasting material and reduce cost.
4. Entangled in the steel pipe, it will generate the anti-corrosion immediately, without the conservation period. Therefore, finished the pipeline coating, lifting operation can be carried out immediately to shorten the operating cycle.
5. Cathode tape stripping rate is low, but the adhesive strength , the impact resistance and penetration resistance of the steel is high,which is a strong anti-corrosion system.
6. Facilitate construction, health and safe operation, without solvents, good environmental performance, whether hand-winding, or machinery winding, can apply.
7. Regardless of diameter size, pipe can be coated from 50 ~ 1800mm .
8. Temperature ranges from -30 to 70 degrees, which is wide, and heat resistance is stable.
