| T400 Cold-applied 3ply Tape |
|
|
 |
For corrosion protection of oil, gas, petrochemical, and waste water underground or overhead pipelines.
Product description:
Construction: four-layer system
Internal Adhesive layer: Butyl rubber
External Adhesive layer: Butyl rubber
Film backing: Special blend of stabilized polyolefines
Interleaf: Anti-adhesive film treated with silicone
The installation is carried out after the liquid adhesive and before the outer-layer tape by hand or with a wrapping machine
|
| Product features/benefits: |
