Innovative Aerolon Coating Resists Corrosion Under Insulation

Tnemec’s high-performance Aerolon thermal insulating coating is the first to be developed using Enova® aerogel by Cabot, the world’s best insulating solid. This coating delivers excellent thermal efficiency. Just as important, it bonds tightly to substrate surfaces, forming a durable, water-tight barrier to resist corrosion under insulation (CUI), which is the most widespread, destructive and costly issue impacting industrial facility infrastructures today.

As an example, commonly used mineral wool has good thermal characteristics, but it is also very vulnerable to moisture infiltration that can cause CUI. The problem often goes undetected until it is too late, because damage can’t easily be seen under the outer cladding.

Another advantage is that Aerolon is part of a complete coatings system. Applied in combination, it represents one of the most effective, corrosion- resistant insulative coatings systems in the industry.

Stratified, Bonded, Layers of Protection

Aerolon is part of a complete coatings system that includes specialty primers and topcoats. The primer bonds to the substrate to resist corrosion. Then Aerolon tightly adheres to the primer, and it’s finished with a thermal topcoat that features suspended ceramic beads for additional energy efficiency. The topcoat also adds UV resistance and stability.
