MCI technology ... protection against corrosion.

Cortec Corporation of the US has introduced a corrosion-inhibiting, modified water-based acrylic peelable coating powered by Migrating Corrosion Inhibitors (MCI) technology.

This powerful multipurpose solution for the construction industry provides mechanical protection against nicks, abrasion, scratches and over-spray to the surface that it covers, says a spokesman for the company.

“It can be used to protect non-porous walls, ceilings, floors, windows, and light fixtures: one coating can do it all,” he says.

In addition, it enables cost savings and corrosion protection to the metals against atmospheric, salt and chemical-induced corrosion.

“This formulation represents the ultimate in non-solvent peelable coatings. It is well stabilised against brittleness and will not be softened or penetrated by solvent-based paints. MCI Peel-off Coating has extremely low VOC (volatile organic compounds) and meets the strictest VOC requirements,” he claims.

According to the spokesman, MCIs are the best solution on the market for restoration challenges. “MCIs extend the useful service life and can cut corrosion rates by a fifth. They are compatible with other materials for flexible and complete restoration and are certified for use in structures containing potable water. MCI technology has successfully passed various evaluations for concrete repair under severe conditions,” he adds.

The MCI Peel-off coating is water-based, VOC compliant, environmentally safe, non-flammable and has excellent sag resistance. It can be disposed of as solid waste; is easy to apply and reduces labour cost by reducing the application time. The coating can be easily removed as it peels off in sheets and does not leave any residue after removal and it contains corrosion inhibitors to prevent corrosion on unpainted metal surfaces.

The MCI Peel-off Coating has also been used to protect glass surfaces during a large construction project.

The spokesman elaborates: “During construction or restoration projects, it is necessary to mask off all glass surfaces to protect them from debris and chemical etching. However, using a masking tape and plastic film is a labour-intensive process that is not always effective since the plastic is susceptible to tearing. Recently, a Cortec’s customer chose MCI Peel-off Coating for coating window frames as an alternative to using plastic film as the product does not etch glass.

“At the end of the project, the coating was easily removed by simply peeling it from the surface. It was then discarded as non-hazardous, solid waste.

“MCI Peel-off Coating worked extremely well as a masking product for glass surfaces: it protected the covered surfaces from debris and chemical etching and provided cost savings by reducing labour and a more effective method of protection.”

MCI Peel-off Coating conforms to Nace Standard RP 0487-2000 and ASTM-2196 and is VOC and RoHS (Restriction of Hazardous Substances) compliant.
