Coatings Under Insulation

Protect What's Beneath — Stop Corrosion Before It Starts

Corrosion Under Insulation is one of the most costly and persistent challenges in industrial maintenance. Advanced Coatings Under Insulation (CUI) systems are engineered to provide long-term corrosion protection in the harshest thermal cycling and moisture conditions, without sacrificing productivity or compliance.

The Corrosion Under Insulation Challenge

Corrosion Under Insulation is a hidden but costly threat to industrial assets. Moisture trapped between insulation and metal surfaces can rapidly degrade pipes, tanks, and equipment, leading to unplanned outages and expensive repairs.

Do not wait for corrosion to surface. With Superior’s advanced CUI systems, you can stop it before it starts.

Industries at Risk of Corrosion Under Insulation:

  • Oil and Gas
  • Petrochemicals
  • Power Generation
  • Food Processing
  • Pulp and Paper
  • Marine and Offshore

Our Coatings Under Insulation are designed to:

  • Withstand extreme temperature fluctuations (-50°C to +650°C)
  • Resist moisture ingress and chloride-induced corrosion
  • Work in high-humidity and saturated insulation environments
  • Have a low VOC, cure fast and are easy to apply
  • Be compatible with insulation systems and jacketing

The Benefits Of CUI Coatings

High-Temperature Resistance

Reliable protection across thermal cycling from cryogenic to extreme heat conditions.

Moisture and Vapor Barrier

Prevents ingress that leads to hidden corrosion.

Proven in CUI Scenarios

Lab and field tested under aggressive corrosion conditions.

Easy Application

Single-coat and multi-coat systems are compatible with standard equipment.

Cost-Effective Lifecycle

Reduces maintenance and inspection costs by preventing early failures.

Industry Certifications

Meets NACE, ISO and major energy sector standards.

Coatings That Go the Distance — Even Under Insulation

The silent threat of Corrosion Under Insulation costs industrial operations millions of dollars every year. Our high-performance coatings are designed specifically to stop corrosion in its tracks – under the most demanding conditions.
