MANUFACTURED BY Advanced Polymerics, Inc.

Advanced Polymerics, Inc.'s patented Permacorr coating effectively mitigates corrosion under insulation – one of the most costly and persistent maintenance challenges for carbon steel assets worldwide. Studies show that corrosion rates increase by approximately 30% for every 10°C temperature rise, and up to 40% of piping maintenance costs in refineries, and solar and chemical plants can be attributed to CUI-related degradation. Permacorr’s chemically bonded phosphate ceramic technology addresses the CUI problem by forming a molecular bond to the steel surface rather than a physical one. This permanent chemical interaction passivates corrosion cells, effectively protecting the substrate against oxygen and moisture. Even if microcracks form from thermal cycling, the underlying bond remains intact, and corrosion cannot start. In the industry-standard Vertical Pipe (Houston) Test, Permacorr demonstrated no blistering, cracking, or corrosion after extended exposure. Permacorr also withstood a six-month cyclic boiling-water test with no observable deterioration, conditions that simulate the 90–120 °C temperature range where condensation, vapor, and liquid water coexist and corrosion rates peak. Because Permacorr is water-based, VOC-free, and non-toxic, it supports sustainability goals without jeopardizing performance. It also does not interfere with non-destructive testing –an important advantage for operators using ultrasonic or radiographic inspection methods.
