CanusaCoat Copolymers

Chemically modified PP and PE copolymers

CanusaCoat™ Copolymers are specially engineered to provide superior bonding of the pipe substrate to the top coat, resulting in a robust mainline coating system.

The copolymers have been formulated to combine high shear strength, lower installation temperature and long-term corrosion protection. In order to facilitate convenient processing of the material for extrusion, the copolymers are supplied in pellet form.

CanusaCoat™ Copolymer Technology

  • CanusaCoat™ PP-1 and PE-1 copolymers bond the polypropylene (PP) top coat and polyethylene (PE) top coat, respectively, to the pipe substrate and as a result eliminates the possibility of moisture ingress
  • High shear strength of the copolymers affirms superior structural integrity and provides robust resistance to pipe movements and the other mechanical forces associated with pipe lay and pipeline operation

Consistent End-to-End Coating Performance

  • A true 3-layer coating system with copolymer applied onto pre-cured epoxy layer, followed by top coat application, for a guaranteed corrosion protection layer

Easy to Install with Process Control

  • High performance is achieved with remarkably low installation temperatures for added repeatability
  • Can be installed directly by contractors, supported by Canusa-CPS’ industry leading field service team, using uniform and controlled induction pre-heating technology and methods of side extrusion
