The PetroWrap® Anti-Corrosion System has been developed for long term protection of metal surfaces that are underground, underwater, or exposed - even in the most severe environments. It consists of a cold applied system of petrolatum-based PetroWrap® Anti-Corrosion Tape, PetroWrap® Primer, and, where contouring is necessary, PetroWrap® Mastic. PetroWrap® adheres to surfaces without heating, even on damp and/or indifferently prepared areas.

The System 

  • PetroWrap® Primer Paste is a preparatory primer that displaces moisture, pacifies oxides, and fills small irregularities that occur on the surface to be wrapped with PetroWrap® Anti-Corrosion Tape.
  • PetroWrap® Mastic is a cold applied filler which profiles areas to be tape wrapped by easing contours on pipe joints, flanges, bolts, and other irregular shapes to be wrapped with PetroWrap® Anti-Corrosion Tape.
  • PetroWrap® Anti-Corrosion Tape consists of a non-woven, stitch bonded, synthetic fabric which has been fully impregnated with neutral petrolatum based compounds and inert fillers.

Application Instructions

  1. Remove all contaminants such as dirt, oil, scale and excessive moisture.
  2. Brush Petrowrap® Primer A evenly over surface to displace remaining moisture and ensure proper adhesion.
  3. Press Petrowrap® Mastic B into surface irregularities to eliminate air pockets.
  4. Wrap Petrowrap® Tape C spirally around prepared surface using even tension. An overlap of 55% is recommended to assure total protection.
  5. Finish with Petrowrap® Overwrap D applied like Petrowrap® Tape to prevent mechanical damage as required.
