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, even under cyclic conditions.
-    An MIO-pigmented 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
