Polyken GO Coat200 High Shear Pipeline Coating System

POLYKEN GO Coat200™
High Shear Pipeline Coating System

System Description

Product Advantages

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

Shear Resistance -- Modified Aleyeska Method

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

Environmental Stress Cracking Resistance

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