Viscoelastic anticorrosion tape
- BrandDEEM
- TypeDM-AT
All materials are completely environmentally friendly, in line with modern anticorrosion design concepts. It is an ideal product for anticorrosion protection and can be widely used in the repair of anticorrosion layers of oil and gas pipelines, the repair of 3PE anticorrosion layer damage, and the anticorrosion protection of irregular-shaped equipment such as flanges, valves, and pumps.
Features
Non-curing viscoelastic polymer with unique cold flow characteristics.
Does not require primer painting, and there is no peeling, cracking, or hardening.
Strong adhesion, good chemical resistance, and no cathode protection peeling phenomenon.
Prevents moisture intrusion and microbial corrosion, making it have unique long-term effectiveness.
Materials
1.Polyethylene 2.Polypropylene(+Reinforced fiber)
Notes
Materials can be customized according to different temperatures and regions.
