Corrosion protection for reinforcing metal

Monday, 14 September 2015

A new water based, environmentally coating provides corrosion protection in outside storage as well as offering corrosion resistance for embedded rebars.

As a soft film, Cortec’s "MCI” coating for rebar is a good choice for long-term indoor protection (up to 5 years) and short to medium-term (6-24 months) unsheltered outdoor protection.

Protecting steel, aluminum, iron and tin

The coating rehabilitates existing concrete structures as well as extending the life span of new structures. Corroding rebar in deteriorating concrete often causes repairs, financial losses and even hard injuries. The product protects steel, aluminum, cast iron and tin. It is dilutable with water and does not affect concrete adhesion to rebar. This safe to use inhibitor cures to a soft film and eventually hardens.

The recommended dry film thickness range is 25-50 microns (1-2 mils). It can be removed by using an alkaline cleaner if needed the coating works well in SO2 and H2S environment.

Typical applications 
  •  protection of rebar partially embedded in concrete
  • jobsite/warehouse storage
  • processing protection
  • overseas shipping
  • maintenance repairs

The coating can be used "as is” or diluted with water up to 50%, as long as a 25-50 microns (1.0-2.0 mils) dry film thickness is reached on surface to be protected. It can be applied by spray, brush, roll or dip.
