SM-633 is a premium novolac epoxy resin in Kukdo’s SM series, designed for protection and sealing in harsh chemical corrosion environments. It features excellent strong acid and alkali resistance and high-temperature stability, forming a dense and tough protective coating.
Strong chemical resistance - Excellent resistance to strong acids, alkalis and organic solvent erosion
High thermal stability - Superior high-temperature resistance, stable performance in a wide temperature range
High crosslinking density - Dense structure after curing, strong anti-permeability
100% solid content - No volatile organic compounds, meeting low-VOC environmental requirements
Excellent bonding and sealing - Firmly bonds to steel, concrete and other substrates with good sealing performance
Chemical anti-corrosion coatings - Protection for inner walls of chemical equipment, acid-alkali tanks and reactors
Secondary containment sealing - Anti-seepage sealing for chemical storage areas, pump stations and trenches
Highly corrosive floors - Floors in highly corrosive environments such as electroplating workshops and battery charging areas
Flue gas desulfurization equipment - Protection for high-temperature corrosive environments such as power plant desulfurization towers and flues
Special sealing materials - Joint sealing of chemical process equipment and gasket preparation
