MasterProtect 8500CI - Dual-phase Corrosion Inhibitor

MasterProtect 8500CI is a single component, ready to use, low viscosity, clear liquid that, combines the power of a 100% reactive penetrating corrosion inhibitor and a latent- phase corrosion inhibitor to mitigate electrochemical corrosion of reinforcing steel in new or aged concrete. Only MasterProtect 8500CI couples the primary reactive penetrant with a second, latent-phase corrosion inhibitor. This latent-phase inhibitor activates when the concrete cracks, migrating to the reinforcing steel to provide an extra level of protection when it is most needed.  

MasterProtect 8500CI is sprayed directly onto the surface of steel reinforced concrete structures and buildings. It is equally suited to cast in situ, precast, post tensioned, prestressed, GFRC, or other steel reinforced concrete. MasterProtect 8500CI can be used as part of an overall repair strategy using MasterEmaco concrete repair systems to mitigate corrosion rates within the balance of the structure and significantly reduce the possibility of “ring anode” induced spalling later. Equally MasterProtect 8500CI can be used as a cost- effective preventative measure before the onset of corrosion induced problems occur. Contact your local Master Builders Solutions representative for further information. It is particularly suited for the protection of:

• Steel reinforced concrete, including cast-in place, precast, pre-stressed and post tensioned

• Building facades and balconies, parking structures, pedestrian walks, bridge decks and supporting elements (beams, columns, etc.), concrete docks and piers

• Marine and other high humidity environments not subject to hydrostatic pressure

• Steel-reinforced concrete exposed to de-icing salts  

• 100% reactive ingredients. No diluents or fillers

• Easy to apply and quick-drying for faster installation time

• Provides water repellent surface to prevent penetration of moisture and chlorides

• Reduces corrosion due to the ring anode or “halo” effect

• Suitable for use in new construction and repair applications

• Effective in chloride-contaminated and carbonated concrete to significantly slow the rate of corrosion

• Latent-phase corrosion inhibitor activates if concrete cracks, or if moisture penetrates into the concrete, providing extended protection when it is most needed

• Vapor-permeable, to prevent moisture entrapment

• Effective in high humidity environments to mitigate corrosion of reinforcing steel.

• Easy to apply surface treatment that penetrates the concrete to bond with steel and the concrete matrix to inhibit microcell (mat-tomat) and microcell (along rebar) corrosion of steel reinforce concrete

• Normally does not require removal prior to subsequent coating applications, thereby reducing downstream labour cost compared with many other corrosion inhibitors.
