Factory Grade™ 3LPE Field-Applied Coating System

The GTS-PE 3LPE coating system is the World’s first heat recoverable coating system designed with Factory Grade™ 3LPE materials, delivering equivalent performance to the factory-applied 3LPE coating.

Compared to other Factory Grade™ 3LPE coating systems, GTS-PE provides very low installation temperatures and a proven, uniform and repeatable application process.

Factory Grade™ 3LPE Coating Technology

  • Polyethylene HDPE top coat delivers mechanical protection and resistance to moisture absorption that is equivalent to the factory-applied coating
  • High temperature liquid epoxy on steel provides Factory Grade™ resistance to corrosion and cathodic disbondment and allows for low installation temperatures
  • PE copolymer layer bonds the PE top coat to the epoxy and fuses to the factory-applied coating to eliminate the possibility of moisture ingress

Consistent End-to-End 3LPE Coating Performance

  • Proven to provide consistent fusion to the factory-applied 3LPE coating
  • A true 3LPE coating system with outer layers applied onto pre-cured epoxy layer for a guaranteed corrosion protection layer
  • Proven on projects requiring the most advanced 3LPE coating performance, including reeling applications and large diameter directional drilling

Easy to Install with Process Control

  • Factory Grade™ 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
  • Can be combined with the patented IntelliCOAT™ system, providing a fully automated, efficient and safe installation
