I. Description

Asphalt Adhesive Tape  is Cold applied tape coating system for corrosion 

protection of Oil, Gas, Petrochemical, Waste Water underground or overhead pipelines and waterproofing.

         The  Asphalt Adhesive Tape  shall be applied after the primer by hand or with 

a wrapping machine.

 

II .Structure

The specification of the Asphalt Adhesive Tape  consists of three layers,

Backing:Special blend of stabilized polyethylene or PVC

Adhesive:Butyl rubber Bituminous Compound and Adhesion Promoting Resins

Interleaf: Anti-adhesive Film Treated with Silicone

 

III .Features:

_ Heavy duty butyl bitumen compound adhesive

_ Excellent adhesion to pipe and self

_ Flexibility provides extra protection at vulnerable areas

_ Excellent conformability and consistent uniform thickness

_ Easily applied with no special equipment

_ Compatible with common pipe coatings

_ Excellent resistance to cathodic disbonding

_ Resistant to UV

_ Can be applied over a wide temperature range 

_ Good conformability and consistent uniform thickness

_ Cold applied
