MasterShield CI 8020

Surface-Applied Corrosion Inhibitor for Dense Concrete and Steel Reinforcement Protection (formerly MasterProtect 8020CI)

How Does MasterShield CI 8020 Work?

MasterShield CI 8020 is a surface-applied corrosion inhibitor designed to migrate through even the densest concrete structures and form a layer on the steel reinforcing bars. MasterShield CI 8020 also protects a multitude of other metals including carbon steel, galvanised steel, and aluminium. The corrosion inhibitor will migrate through concrete until it finds steel to create a protective layer on. MasterShield CI 8020 will stop the further corrosion of reinforcing metals and extend the service life of the structure.

Recommended Uses:

• All reinforced, precast, prestressed, post-tensioned, or marine concrete structures

• Steel-reinforced concrete bridges, highways, parking decks, ramps, and garages exposed to corrosive environments (carbonation, de-icing salts, and salt spray)

• Concrete piers, dams, offshore platforms, piles, pillars, pipes, and utility poles

• Preventative maintenance, restoration, and repair of all reinforced concrete commercial and civil-engineered structures

• Cooling towers and potable water tanks

What Are the Unique Features of MasterShield CI 8020?

MasterShield CI 8020 penetrates the concrete to find and protect the reinforcing steel. It offers engineers, owners, contractors, and government authorities a time-proven corrosion-inhibiting technology that will extend the life of all reinforced concrete structures.

What Are the Benefits of MasterShield CI 8020?

• Slows existing corrosion – reduces the corrosion rate of corroding steel not yet visible

• Preventative treatment – protects new structures where insufficient cover is an issue

• Controls incipient anodes – stops the formation of incipient anodes at new to old concrete interface

• Does not interfere with the bond of repair mortars or coatings – can be used directly onto areas to be repaired

• Forms passive layer underneath rust on steel – slows corrosion to allow for longer-term repair strategy to be put in place

• Easy application - spray, roller, squeegee, or paintbrush to any concrete surface

• Water-based - for easy handling and application

• Allows concrete to breathe and vapour to diffuse - is not a vapour barrier

• Dual action inhibitor - protects both anodic and cathodic areas

• No cure time required - traffic may resume minutes after application if necessary
