Cortec’s MCI-309 is said to be a powerful Vapor phase Corrosion Inhibitor powder for corrosion protection of ferrous metals and aluminum in recessed areas, interior cavities and voids. It provides an extremely efficient dry method protecting metals within an enclosed space.
The MCI vaporizes and adsorbs on the metal surfaces, reaching all exposed areas, including recessed sections and interior cavities. This mixed inhibitor provides protection to both the cathodic and anodic sites of metal. MCI-309 does not affect physical properties of concrete or grout (set time, strengths, etc.), and it is safe for high tensile strength steel (will not cause hydrogen embrittlement).
Corroding rebar in deteriorating concrete often causes costly repairs, financial losses and serious injuries. MCI technology offers the most contemporary solutions on the market to prevent this from happening. Cortec MCI products for concrete maintain structural integrity, rehabilitate vulnerable structures, and alleviate environmental concerns. MCI-309 creates a monomolecular inhibiting layer and enables up to 24 months of continuous protection.
Protected surfaces do not have to be cleaned prior to concrete or grout placement. If the MCI layer is disturbed by moisture or by opening the enclosed space, the layer is replenished by continuous vapor redeposition. MCI-309 does not contain silicates, phosphates, nitrites, or heavy metals. This easy to apply powder requires little or no surface preparation and prevents further corrosion of pre-coated and painted surfaces. The layer does not need to be removed prior to processing or use. The powder can be removed by air gun or water.
