APCOTHERM 800 CUI
APCOTHERM 800 CUI is a single‑pack, patented inorganic copolymer coating infused with MIO and high heat‑resisting pigments. It is an air‑drying high‑temperature resistant system designed to protect carbon steel and stainless steel against atmospheric corrosion, corrosion under insulation (CUI), and corrosion on buried high‑temperature vessels and underground pipelines. After curing, it forms an inert multi‑polymer matrix with operating temperature capability from ‑196°C up to +850°C (subject to substrate/material of construction).
