APCOTHERM 800 CUI

System Description:

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).

Key Features

850°C dry operational continuous temperature resistance for stainless steel surfaces.
750°C dry operational continuous temperature resistance for carbon steel surfaces.
250 um DFT High build single coat DTM application or over a zinc silicate primer for up to CX exposures
200 °C, Suitable for hot steel surface application during shutdowns & maintenance.
-196°C, Suitable for use in thermal shock/ rapid cycling in dry or dry/wet service temperatures.
Protects SS from chloride attack by forming a protective barrier.
Protect austenitic and DSS by preventing external stress corrosion cracking.
Outstanding Weathering & UV resistance and durability along with good chemical resistance.
Conforms to NACE SP0198 - 2017 systems SS-5, CS-6 and CS-8.
