Introduction
Performance Features
01 · Effective Cathodic Disbondment Resistance and Excellent Protection
Based on its excellent adhesion performance, the coating effectively resists cathodic disbondment, reduces corrosion propagation, improves long-term pipeline protection capability, and ensures stable operation of the anticorrosion system.
02 · Superior Substrate Protection and Compatibility with 3LPE Structure
As an important component of the 3LPE anticorrosion system, it provides excellent mechanical properties and chemical stability. It bonds firmly with the polyethylene outer layer, improving the overall anticorrosion performance.
03 · Excellent Interlayer Compatibility and Long-Term Corrosion Protection
With a specially designed formulation, the coating provides excellent interlayer bonding performance and good compatibility with other anticorrosion materials, effectively extending the overall service life of pipelines.
04 · Fast Curing and Wide Engineering Applicability
The coating features fast curing speed and high construction efficiency. It is suitable for long-distance oil and natural gas pipeline projects, meeting the requirements of large-scale anticorrosion applications.
Application Field
Suitable for:
Various anticorrosion pipeline applications, including oil transmission pipelines and gas transmission pipelines.
