Conproco ECB 1G: Electro-Chemical Barrier
Conproco ECB, corrosion of reinforcing steel is the number one cause of failures in concrete. Getting 100% coverage of the rebar is essential to the long-term performance of the repair. Conproco ECB is a single component, zinc-rich acrylic coating. It does not require any mixing. All loose scale must be cleaned from the rebar. ECB can be painted or sprayed onto the steel as well as the concrete because it is not a bond-breaker. The orange color makes it easy to inspect for proper coverage. ECB can remain exposed for up to 30 days before either reapplying (no preparation required other than cleaning out any debris) or placing repair material. Because there is no mixing, there is no waste, simply replace the cover until the next use. Questions? Contact Us.
- Performance Characteristics:
Multiple defenses Barrier coating. Corrosion inhibitor. Prevent anode transfer.
Water vapor permeable.
- Ease of use
Single component, water based technology. Orange color clearly defines application area.
Does not produce destructive byproducts.
- Long open time
Up to 30 days on steel before covering.
Up to 5 days on concrete before covering.
- Thermal compatibility
Will not cause delamination due to temperature change.
- Ease of application
Spray apply to increase production.
- Ease of clean up
Clean equipment with water.
- Environmentally friendly
Water based, low odor, non-flammable.
- Surface Preparation:
Mechanically remove all scaling rust from metal.
Remove concrete around rebar to provide a minimum 3/4 inch clearance.
Remove concrete along the length of the bar until the exposed bar shows no sign of corrosion activity.
- Concrete: Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper adhesion.
- Priming ECB is a priming treatment.
Stir or mechanically mix using a low speed drill (400 – 600 rpm) until homogeneous.
Brush or spray apply a uniform 7 mils. wet to all exposed steel.
For spray applications use a Graco 3500 or equivalent.
Brush or spray apply a uniform 7 mils. wet to prepared concrete surface when using as a bonding primer.
In severe environments a 2 coat application on steel is recommended.
