MCU-Mastic

MCU-Mastic is a single component moisture cure polyurea coating.

MCU-Mastic is a corrosion and chemical resistant intermediate and finish coat for non-UV exposure that has outstanding barrier performance, whether used for atmospheric exposures or in immersed environments. MCU-Mastic has a smooth finish and is ideal for interior applications as a finish coat. MCU-Mastic is available in light grey colours to facilitate interior tank inspections. MCU-Mastic is approved for contact with potable water and foodstuffs (EU). 

MCU-Mastic is also the standard primer for non-ferrous and concrete surfaces, and the standard sealer coat for concrete as the primer/barrier coat for their anti-carbonation system. 

• Universal intermediate/barrier coating
• Coloured topcoat for interior use where there is limited UV exposure and slight ambering is acceptable
• Aromatic topcoat to replace epoxies
• High resistance to atmospheric chemicals
• Best choice in salt or fresh water immersion service
• Ideal for use over MCU primers in ballast tanks and cargo holds
• Use as a standard primer for non-ferrous and concrete surfaces
• Approved for contact with potable water and food
