Versiline CUI
Description
Versiline CUI 56990 is a MIO pigmented, fibre reinforced, inorganic co-polymer coating that cures to an inert polymer matrix, able to resist temperatures up to 650°C [1200°F] and thermal shock/cycling in dry or dry/wet service. Conforms to NACE SP0198 - 2017 systems SS-5, CS-6 and CS-8. Approved to Saudi Aramco APCS-11C.
Recommended use
Versiline CUI 56990 is recommended for long term protection of hot pipework, equipment and other hot surfaces. The product is specially developed to prevent corrosion under insulation (CUI) and is applied directly onto the steel substrate or over a zinc silicate primer.
Trusted for over 40 years
A fast and effective solution to CUI
Versiline CUI 56990 will reduce your overall lifecycle costs and ensure you benefit from longer uptime
Corrosion under insulation (CUI) is one of the major challenges facing equipment operators in the process industries today – and it can lead to significant lost revenue from downtime, maintenance and replacement of corroded parts.
Increased heat resistance and excellent application properties
Versiline CUI 56990 provides long-term protection for hot pipework, equipment and other hot surfaces. Its excellent heat-resistant properties make it extremely resistant to micro-cracking, even when subjected to extreme temperatures. In addition, carefully selected barrier pigments make it highly effective against CUI, especially under cyclic conditions.
- An MIO-pigmented fibre reinforced single-component inorganic copolymer coating that cures to form an inert polymer matrix
- Resistant to temperatures from cryogenic (-196℃) up to 650℃
- Resistant to thermal shock/cycling in dry or dry/wet service conditions
- Can be used on carbon and various types of austenitic and duplex stainless steels
- Can be applied to hot surfaces in maintenance situations or to grit-blasted steel for newly constructed pipework and equipment
The hardness, impact resistance and excellent adhesion of Versiline CUI 56990 make it especially suited for offsite application.
