ECB is a brush or spray applied, water based, single component anti-corrosion coating and long open time bonding primer that prevents rusting of rebar. Mechanically remove rust from rebar and apply.
Where to use:
Protect reinforcing steel and metal embedded in concrete against corrosion.How to apply:
Spray or brush applied. Additional InformationMinimize InformationPerformance Characteristics
- Multiple defenses Barrier coating. Corrosion inhibitor. Prevent anode transfer.
- Breathability Water vapor permeable.
- Ease of use Single component, water based technology. Orange color clearly defines application area.
- Stable Does not produce destructive by- products.
- 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
Reinforcing Steel- 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.
- Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper adhesion.
Priming
- ECB is a priming treatment.
Mixing
- Stir or mechanically mix using a low speed drill (400 – 600 rpm) until homogeneous.
Application
- Brush or spray apply a uniform 7 mils. wet to all exposed steel.
- For spray applications use a Graco 3500 or equivalent. Refer to Conproco Black Book.
- 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.
Curing
- Allow ECB to dry for a minimum of 30 minutes @ 70°F and be dry-to-touch before placing covering material or applying a second coat.
Clean Up
- Clean tools and equipment with water after use.
Coverage/Yield
Packaging/Reinforcing Steel- 1 gal. – 900 ft. of #8 rebar.
- 5 gal. – 4500 ft. of #8 rebar.
- 1 gal. – 230 ft.² @ 7 mils.
- 5 gal. – 1150 ft.² @ 7 mils.
Product Handling
- Packaging 1 and 5 gallon plastic containers.
- Shelf Life 18 months in unopened containers.
- Storage Protect from freezing. Transport and store in cool, clean, dry conditions in unopened containers. High temperature will reduce shelf life.
Limitations
- Do not apply unless substrate and ambient temperature can be maintained at a minimum of 40°F for 24 hours.
- Cure time at 40°F is approximately 24 hours. ECB must be dry-to- touch prior to placing covering material.
- Repair zone should be cleaned of dirt and dust immediately prior to placement of concrete or repair material.
- Metal to be coated must be free of all scaling rust at the time of application.
Health and Safety
- Avoid contact with eyes.
- Do not ingest.
- Refer to Safety Data Sheet (SDS) for additional information.
First Aid
- In case of eye contact, flush immediately with a high volume of water for at least 15 minutes and contact a medical professional.
Disposal
- Dispose of material in accordance with local, state and federal regulations.
