The specification of the tape consists of two layers, adhesive layer and film backing

Adhesive: butyl rubber

Outer layer: 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,EN 12068,AWWA C 214 Standard

Cold applied
