WebImportantly, the cured LE AMSS 36375 coating displayed excellent cleanability. The utility of LE coatings is in the suppression of TIR. If the LE coating were to be permanently contaminated by high-emissivity materials during use, it would lose the attribute to deliver LE properties. Therefore, the CE of the LE coating is critically important.
