Cortec has developed an alternative to solvent-based sealers for protecting concrete from moisture and chemicals.
Cortec Corporation has recently announced the launch of MCI®-2026 Primer WB, water- based coating that can help to seal out moisture and protect concrete.
The porous nature of concrete makes it very susceptible to moisture, whether it is seeping up from the ground beneath or penetrating down from wet materials on the surface above. In addition, also UV light and chemicals can damage the substrate and cause premature degradation. Sealers can then help to extend service life in many circumstances.
MCI-2026 Primer WB is a two-component 52% solids water-based epoxy coating system that offers increased moisture and chemical resistance, as well as reduced flammability. The low viscosity allows for greater substrate penetration, improved handling and easier application, while the lack of solvent odours makes MCI®-2026 Primer WB inoffensive during indoor applications.
Compared to traditional solvent-based concrete sealer systems, it is more durable and ensures an easier clean-up after application. In addition, MCI-2026 Concrete Primer has excellent adhesion and dries quickly in one to three hours before it can be recoated. At <60 g/L VOC per EPA Method 24, it is compliant to all VOC/HAPS regulations and it also meets all of the USDA/FDA guidelines for use in federally inspected facilities.
Although MCI-2026 Concrete Primer WB is a standalone concrete sealer – and an economical alternative to its 100% solids novolac epoxy coating counterpart – it can be applied in two coats for extra durability, creating a tough concrete sealer system for heavy (rolling) traffic: when combined with MCI-2026 Floor Coating as a base primer, it results in an extra tough barrier to moisture, chemicals and physical abrasion.
The new solution developed by Cortec is available in clear or grey colours, in order to provide fresh and/or inconspicuous appearance. For example, it can the by applied on garage, laboratory, factory, facility and shop floors, as well as in many other industrial environments where there is frequent spillage, cleaning, cart or vehicle traffic and residual oils or greases.
