Advantages

• Purple TPO facer identifies wastewater pipelines.
• 350-35 proprietary butyl adhesive was developed for the harsh conditions of the Alaskan Pipeline in the 1970’s. Our tape can be applied down to -10°F and has excellent high temperature resistance to 300°F.
• The facer offers excellent conformability to irregular surfaces and has high puncture resistance to rough back fill materials.
• Has an excellent resistance to water and vapor transmission.
• Can be used for sealing concrete joints in man holes and sewer lines.
• Adheres to steel, cast iron, PVC, epoxy coatings, concrete and most any surface through the primer coat.
• The elastomeric properties of the 350-35 accommodate expansion and contraction of the substrate and in-service pipelines.
• Provides uniform factory controlled thickness compared to field applied liquid coatings.

Application Procedure

• Apply Protecto Wrap G Primer or Universal Water Based Primer to the cleaned surface with a paint brush or roller. Allow primer to dry to a tacky but not wet state. Do not cover wet primer.
• Remove the release liner from the tape for 6" and begin wrapping the pipe. Tension should be pulled on the tape during installation, smoothing the tape as it comes into contact with the primed pipe. When using spiral applications make sure overlap is a minimum of 2". With cigarette wrapping end lap should be a minimum of 4".
• Remove and discard the backing separator from the tape as you wrap.
• Firmly press overlap seams to insure a firm contact and bond.
