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. |
