The HLD-T300 series is Cold applied tape coating system for anti corrosion of field joints, fittings, and specifically piping.
The adhesive is a key in ground performance characteristic coupled with the low and high density polyethylene backing.
The Joint wrap tape shall be applied by hand or with a wrapping machine.
The specification of the tape consists of two layers, adhesive layer and film backing
Adhesive: butyl rubber
Film backing: Special blend of stabilized polyethylene
Heavy duty adhesive
Resistant to UV
Can be applied over a wide temperature range
Good conformability and consistent uniform thickness
Easily applied with no special equipment
Conformable to irregular shapes.
Meets ASTM D 1000 Standard
