ECB

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 Information

Performance 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.
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.

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.
Packaging/Concrete
  • 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.

For Cement Based Materials

The gallons per minute volume of a rotor/stator pump is determined by the pump size (i.e. size 6 has a larger capacity than size 3). The pressure capacity of a pump is determined by the number of stages. Thicker materials and longer distances require higher pressure.

Corrosion is the primary cause of failures in concrete.  When water reaches reinforcing steel the corrosion process begins. Corrosion produces iron oxide (rust). Rust is an expansive force that causes cracking in concrete.                

Cracking provides a pathway for water and environmental contaminants to reach rebar which results in more corrosion in a continuous cycle that can lead to costly repairs.  Repairs to concrete should always include treating rebar with an anti-corrosion coating.        

ECB (Electro-Chemical Barrier) incorporates zinc technology to prevent corrosion using sacrificial chemistry in addition to passive and integral anti-corrosion chemistries.           

ECB can be left uncovered on rebar for up to 30 days simplifying job site scheduling.
