ⅠSystem description:
The XUNDA-T400 series is Cold Applied Tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water underground ,offshore or overhead pipelines. It is also used as inner-layer tape.
The 3 Ply tape shall be applied after the Liquid adhesive and before the outer-layer tape by hand or with a Wrapping machine
II Structure
Double coated anticorrosion adhesive tape consists of four layers,
Internal Adhesive layer:butyl rubber
External Adhesive layer: Butyl rubber
Film backing:Special blend of stabilized polyolefines
Interleaf: Antiadhesive Film Treated with Silicone
Ⅲ Features:
Excellent bonding between adhesive and carrier film via co-extruded intermediate layer.
Mechanically highly resistant tape system.
Practically impermeable to water vapour and oxygen.
Resistant to soil bacterial and soil electrolyte.
Compatible with coating from PE,PP,FBE,PU,CTE and Bitumen and ext… .
A Total Coating System with:
High adhesion and shear resistance
Resistance to corrosion disbondment
High electrical resistance
High dielectric strength
High corrosion protection for steel substrates
