Example of this Liquid Applied Insulation Coating
An evaporator at a UK based chemical company required a coating to help reduce heat loss and the surface temperature. The surface temperature was measured at 203°F. In addition, the substrate was mechanically abraded using handheld grinders. Then, the use of 107 Metal Repair Paste XL filled any corrosion pitting. Once cured, the first coat of 561 Thermal Barrier was applied at 4-8 mils WFT. It was then allowed to cure for 2 hours. Once dry, a 2nd coat was applied at 408 mils. The following coats were applied at 0.4 in. each to give a total DFT of .15 in. The surface temperature was measured at 185°F-235°F once the application has been completed, a 60% reduction in surface temperature.
