Visco Elastic Coating Tape
Visco-elastic anticorrosive tape is a new-type high-performance viscoelastic polyolefin material. It preserves the dual characteristics of the 100% solid adhesive material and liquid adhesive material. In normal conditions, its viscoelastic property will keep above 30 years.
Product Description
System Description
Visco-elastic anticorrosive tape is a new-type high-performance viscoelastic polyolefin material. It preserves the dual characteristics of the 100% solid adhesive material and liquid adhesive material. In normal conditions, its viscoelastic property will keep above 30 years.
Features
-Is easy to use and can be applied in almost any situation, including below- and above-grade structures and steel pipelines,elbow pipe, pipe bending, three joints and insulated flange.
-Remains flexible even after decades
-Adheres to any dry surface, such as concrete, steel, pvc, piping, ducts, etc.
-Is easy and safe to use. No primers, solvents or heating are required.
