Belzona 5831 (ST-Barrier)

Moisture-Tolerant Protective Barrier Coating

A moisture-tolerant epoxy coating for corrosion protection of wet and oil contaminated surfaces.

Belzona 5831 (ST-Barrier) is an environmental moisture-tolerant barrier coating for the protection of metallic and non-metallic surfaces.

It has been specifically formulated for application to surfaces that cannot be dry for application. The product displaces contaminants from the surface ensuring maximum adhesion to damp, wet or oily surfaces and even underwater.

This solvent-free material can be applied to virtually any surface and will cure even in low temperature environments, as well as underwater.

Key Benefits:

  • Simple mixing ratio
  • Application and cure at room temperature – no hot work involved
  • Cures underwater
  • Reduced health and safety risks as it is solvent-free
  • Excellent bonding to wet surfaces
  • Tolerant to oil contamination
  • No shrinkage, expansion or distortion
  • Prevents galvanic corrosion
  • Excellent bonding to many metal surfaces including steel, stainless steel and other specialist steels as well as to non-metallic surfaces such as concrete and brick

Applications for Belzona 5831 (ST-Barrier) include:

  • Prevention of corrosion and deterioration of metalic substrates in splash zones, pipework, tanks, bunds and clarifiers
  • Protecting submersible pumps, valves and transformers from the effects of galvanic corrosion
  • Long-term repair and coating of oil and water leaks
  • Sealing of joints and flanges
