Polyken GO Coat250 High Temperature Pipeline Coating Systems

POLYKEN GO COAT250™
High Temperature Pipeline
Coating System

System Description

Product Advantages

The Polyken GO Coat250™ system is designed for the corrosion protection of new and existing pipelines with a maximum operating temperature of 250°F (121°C). The primer layer is a solvent based, thermally activated material formulated for elevated temperature stability. The coating layer consists of a polypropylene backing and a cross-linked elastomeric adhesive capable of maintaining long term protection at elevated temperatures.

User-friendly application to new or operating pipelines.

Shear resistant at elevated temperatures.

Retains long-term flexibility.

Manufactured at ISO certified facility.

Plant or in-field application.

Retention of Elongation at 250°F – ASTM D1000

The Polyken GO Coat250 system is designed to maintain coating integrity and efficiency after long-term exposure to elevated temperatures. In red: GO Coat250. In purple: PE Tape.

Shear Resistance (hours, time to move 5 cm)

The cross-linked elastomeric adhesive resist the normal soil and pipe movement stress that can occur on a high temperature pipeline.
