HBE-DX™

High Build Epoxy coating with Abrasion and Corrosion Resistance

The Canusa HBE-DX is a robust liquid epoxy coating system specifically designed to protect field joint girth welds during directional drilling pipeline construction.

The formulation presents high properties of gouge resistance, tensile elongation, impact strength and ease of build. Applied as a standalone direct-to-steel coating system, HBE-DX has proven to withstand pipe operating temperatures up to 95°C (203°F) with excellent anticorrosion performance. This environmentally friendly, 100% solids, novolac epoxy system can either be spray applied or brush applied to the intended substrate

Directional Drill Compatibility

  • High gouge resistance, tensile elongation, impact resistance and flexibility are the major performance characteristics worked into the HBE-DX formulation

Corrosion Protection up to 95°C

  • HBE-DX coating system was designed to protect operating pipelines up to 95°C

Superior Performance

  • HBE-DX has proven to outperform competitive equivalents in a variety of test methods for corrosion and mechanical resistance

Fast Cure

  • HBE-DX’s cure component comes standard with Canusa’s proprietary Fast Cure option

High Build in Single Coat

  • A single pass application direct-to-metal will achieve a high build coating thickness of 20-40mils (500-1000 microns)
