Adhesive: butyl rubber
Outer layer: Special blend of stabilized polyethyleneIII Features:
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
Cold applied
