ⅠSystem description:
The XUNDA-T200 series is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water underground or overhead pipelines. The outer-layer tape backing shall be compounded so that it will be resistance to outdoor weathering.
The outer-layer tape shall be applied after the inner-layer tape by hand or with a wrapping machine
ⅡStructure:
The specification of the tape consists of two layers, adhesive layer and film backing
Adhesive: butyl rubber
Film backingr: Special blend of stabilized polyethylene
Ⅲ Features:
Excellent adhesion to inner-layer tape and self
Resistant to UV
Can be applied over a wide temperature range
Good conformability and consistent uniform thickness
Easily applied with no special equipment
Compatible with common pipe coatings
Excellent resistance to cathodic disbonding
Meets ASTM D 1000 Standard
Cold applied
