The Canusa GTS-PP-65 3-Layer system provides superior corrosion protection, resistance to soil stress and excellent bonding to polypropylene coated pipelines operating up to 65°C. GTS-PP-65 3-Layer has been designed with a unique crosslinked polypropylene backing and a high performance adhesive. Much lower installation preheats are required compared to other polypropylene based systems.

Mechanical Resistance: The PP backing layer of the GTS-PP-65 3-Layer is fabricated using the equivalent raw materials as used for extrusion of PP mainline coatings. As a result, the mechanical properties achieved using this system are directly comparable to those achieved by 3LPP mainline coatings, including excellent resistance to impact, indentation, abrasion and for hardness.

Force Cured Epoxy Method: Canusa’s proven method of force curing the epoxy primer to the steel allows the installer to “pre-inspect” the joint prior to sleeve application. The epoxy will not be displaced during the aligning and shrinking stages of the sleeve installation. This provides the assurance that the pipe is fully protected. Canusa’s epoxy primer can be applied to an even, nominal thickness for maximum corrosion protection.

Unique Adhesion Technology: Canusa's unique adhesive technology allows for lower installation pre-heats and superior bonding to PP coatings. The adhesive has been formulated to bond directly to the main line coating; epoxy is applied to the steel only. The result is a superior bond to the substrate, easier application and significant cost savings.
