CUI is a common term used for corrosion under insulation. Corrosion on insulated tanks is a big threat to safety, productivity, and the bottom line. The right protective coating is crucial. In this article we will be comparing the EonCoat CUI coating vs. polymeric CUI coatings and we will break them down into 2 sections.
Surface preparation
A near-white metal blast (SSPC 10) is required for polymeric coatings
To prepare the surface for either of the two coatings it generally needs
to properly adhere. Once the blast has been performed, the coating
