System Description

The Polyken GO Coat200™ system is designed for in field application on pipe where soil stress conditions exist and with a maximum operating temperature of 200°F (93°C). The system consists of a solvent based elastomeric primer, an anti-corrosion layer formulated with a high shear elastomeric adhesive, and a mechanical protection layer formulated with a stabilized polymeric backing for long-term stability at elevated temperatures.

• Shear resistant up to 200°F (93°C)
• Thermally stable polymeric backing
• Incorporated SCC inhibitors
• Established in-ground history
• New construction or reconditioning of
  existing pipelines

The crosslinked adhesive of the GO Coat System resists the normal soil and pipe movement stresses that can occur on a pipeline.

When subjected to simulated field conditions, Polyken's GO Coat200 System exhibits superior resistance to stress cracking compared to a conventional polyethylene-based system.
