Guardian Bituwrap Systems
A Medium to Heavy-Duty Cold Applied Bitumen Tape / PVC Pipe wrap for use in situations where a tough conformable pipe wrap coating is required.
The Guardian Bituwrap Systems are robust systems designed to be used along with Guardian Bituwrap Primer, for some of the harshest buried condition, comprising of various plastic backing in conjunction with bituminous rubber adhesives. Our Bitumen tapes offer superior adhesion to steel substrates, offering multiple grades of protection, including protection at high temperatures and are well suited for use in tropical climates.
- The surfaces must be dry, load-bearing, free from grease and dust, and must not be frozen.
- The surface temperature must not fall below +5?C. At lower temperatures, the surface to be processed must be preheated with a gas burner or a hot-air device while taking the applicable safety precautions into account.
- Absorbent and porous surfaces must be pre-treated with butyl/bitumen primer.
- To ensure proper adhesion, the tape must be pressed onto the surface and smoothed with a press-on roller or a similar tool. When connecting strips, the overlap should be at least 50 mm.
Extruded PVC Carrier engineered for toughness, conformability and controlled elasticity. Compound formulation designed to give maximum adhesion in a wide variety of application temperatures and includes underwater applications. It can be used for outdoor applications and is resistant to rain and all other weather conditions

GUARDIAN BITUWRAP 1650 Bitumen Tape
The GUARDIAN BITUWRAP 1650 tape, to be used along with Guardian Bituwrap Primer, is a heavy-duty cold applied 2-ply PVC/Bituminous Rubber (Bitumen) system, supplied with an overwidth siliconized paper interleaving, that is designed for use in industries that require high impact resistant and robust pipe wrap coating. Like all GUARDIAN BITUWRAP systems, the Guardian Bituwrap 1650 PVC/Bitumen Tape System complies with the AWWA C209-19 standard.
The Guardian Bituwrap 1650 Tape is a highly self-adhesive anti-corrosion bituminous rubber compound which allows it to provide a high level of adhesion to a properly primed steel substrate. The GUARDIAN BITUWRAP 1650 tape is ideal for use on buried pipelines with selected backfill medium. They are an excellent solution for use in continuous line pipe wrapping, pipeline bends and protection of field joints.
Surface Preparation: St2 or better.
Conformability: Extruded PVC Carrier Engineered for Toughness, Conformability and Controlled Elasticity. Versatility: Compound formulated for Maximum Adhesion for different applications and environments.
