MCI® can be applied to existing structures as a surface treatment that reduces corrosion rates. This surface treatment is designed to penetrate into and migrate through cementitious materials to reach and protect embedded reinforcing metal. MCI® surface treatments can be applied on vertical and overhead surfaces, as well as horizontal surfaces.
MCI® pure inhibitors do not contain water repellants but provide extra-strength corrosion protection to embedded rebar through a powerful dose of MCI® inhibitors. These straight inhibitors work at rebar level to effectively protect reinforcing metal from corrosive elements with or without the use of sealers. MCI® sealers combine water repellency with the added protection of Migrating Corrosion Inhibitors. These
MCI® surface treatments seal surface pores to block carbonation and protect against the ingress of water, chlorides, and other aggressive contaminants. Below the surface, MCI® penetrates to the depth of embedded metallic reinforcement to form a protective monomolecular layer on the surface of the rebar. This protective layer delays the onset of corrosion and reduces corrosion rates after initiation, greatly extending the service life of structures.
MCI®-2020 M V/O
|Blend of amino-alcohol and salts of carboxylic acids
|Corrosion inhibiting admixtures that do not effect the physical properties of concrete mix. Mixed inhibitors meaning they protect both the cathode and the anode. Made out of organic based materials hence have lower toxicity and environmental impact than traditional corrosion inhibiting admixtures (e.g.calcium nitrite). Have the capability to migrate to adjacent areas to protect surrounding materials. Only needs to be applied with a single dosage rate irrespective of anticipated exposure to corrosive elements. Both have been thoroughly lab and field tested with extensive history of case studies.

|Varied 3.68m2/L (consult product
data sheet for further details)
|Corrosion inhibitor with water repellent properties provided by silane component. Silane chemically reacts with calcium hydroxide within cement to form hydrophobic layer under alkaline conditions. MCI®
component penetrates deeper into concrete to form protective molecular layer on reinforcing metal to inhibit corrosion. Certified to meet ANSI/NSF Standard 61 (use with potable water) and EN 1504-2 (2+System). Concrete surfaces remains fully breathable and maintain their natural moisture-vapour transmission.

Product and customer insights
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.

AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
