Description

A new, supercharged, dual- action, penetrating, clear, surface applied blend of organofunctional corrosion inhibitors based upon amino alcohol technology that inhibits the electrochemical corrosion process between the steel (rebar), chloride ions, oxygen and moisture within concrete.

Iso-Tek® 8511 impregnates the concrete forming a protective barrier on the surface of the steel reinforcement reducing the rate of corrosion in carbonated and chloride contaminated concrete inhibiting rust and carbonization, while simultaneously protecting against water-soluble deleterious materials. With it’s long established hydrophobic agents, amino- alcohol technology and through the latest advances in nanotechnology, its corrosion inhibiting technology provides an extra layer of protection for structurally reinforced concrete

Applications

Exceptional when used for:
  • Bridges and highway infrastructure
  • Rail and metro systems
  • Concrete balconies
  • Reinforced concrete structures
  • Marine and high-humidity environments
  • Traffic-bearing concrete substrates
  • Concrete ramps and barriers
  • Parking structures
  • Structurally-reinforced stadiums and buildings
  • Architecturally-reinforced concrete
  • Precast
  • Post-tension
  • Steel-reinforced cast-in-place concrete

Benefits

Provides

  • Composition - Dual-action penetrating organofunctional corrosion inhibitor and water repellent treatment based upon amino alcohol technology for structurally reinforced concrete that inhibits the electrochemical corrosion process of the steel within the concrete
  • Reduces high and low corrosion rates by anodic, cathodic control and concrete resistivity principles
  • Dramatic reduction in the chloride-ion-induced corrosion rate of concrete steel reinforcement
  • Improves durability - Prevents capillary uptake of water and the aggressive corrosive substances dissolved in it

Minimizes

  • Forms a protective passivating coating that chemically bonds with steel reinforcement
  • Significantly inhibits the onset and rate of corrosion of carbon and galvanized steel rebar
  • Resists freeze thaw and thermal cycling damage
  • Mitigates the corrosion of rebar in structures exposed in high humidity environments
  • Excellent penetration depth into structurally reinforced concrete.

Reduces

  • Odorless excellent for cold weather applications
  • Natural flat finish - Does not change surface appearance, UV stable will not breakdown with light exposure
  • Reduces the rate of corrosion in carbonated and chloride contaminated concrete
  • 100% breathable - Non-film forming. Allows moisture within the concrete to escape without adverse effects to the sealer.

Technical Documents

Auxiliary Information

  • Preparation

    1. New “green” concrete must be properly cured. Concrete should obtain 80% of design strength, typically achieved within 14-28 days.
    2. The concrete substrate must be structurally sound and clean of oil, grease, dirt, wax, curing compounds, efflorescence, paints, previous sealers, adhesives and other contaminants that might interfere with the penetration of the sealer. Power wash, acid etch or mechanically scarify as necessary to achieve the desired surface condition. Allow for proper dry time before application. May be applied to slightly damp surfaces, although maximum penetration is achieved on dry substrates. Do not apply if standing water is visible.
    3. Surface and air temperatures must be at least 35°F during application. Surface and air temperatures should not exceed 95°F. Do not apply when temperatures are expected to fall below 32°F within 8 hours or when rain is expected within 12 hours following application. Keep material from freezing. If freezing conditions exist before application, let the substrate thaw before application. Do not apply during inclement weather or when inclement weather is expected within 12 hours.
    4. Crack, patching and expansion joint sealants can be applied before application; always test for compatibility and adhesion.
    5. Protect people, property, vehicles, window glass, roofing materials, plastic products, shrubbery, landscaping and all surfaces not set for treatment from overspray.

  • Application

    1. Always test a small area before application to ensure desired performance, aesthetics, coverage rates and to verify application technique. Let test area dry thoroughly, 5-7 days, before inspection.
    2. Stir material throughly before and during application. Do not dilute or alter material for purposes other than specified.
    3. Two wet-on-wet coats are needed to ensure complete coverage. Note: a third coat may be necessary depending upon the application. Verify coverage with a KreteTek product representative prior to application. Apply with a solvent-resistant roller, brush or low-pressure, non-atomizing sprayer. Apply to saturation and let the first coat penetrate for 5-10 minutes then reapply a second coat in the same saturating manner. Less material will be needed for the second coat. Roll or broom out any puddles until the product penetrates the substrate. If it starts to rain, stop treatment and cover the impregnated areas.

  • Notes

    Dry Time Typical drying time is 4-6 hours at 70°F and 50% relative humidity. Cooler temperatures or higher relative humidity can extend the drying time. Treated surfaces will be ready for pedestrian and vehicle traffic within 24 hours.

    Clean Up Clean equipment and tools with xylene. Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

    Precautions/Safety Avoid contact with skin, eyes and clothing, do not take internally. Use appropriate safety equipment during application and handling. Please refer to the safety data sheet (SDS) for additional precautionary instructions before use. For medical emergencies only, call ChemTrec (1-800-424-9300).

    Best Performance (application notes)

    • Proper application is the responsibility of the user.
    • Will not inhibit water penetration through unsound or cracked surfaces with defective flashing, caulking or structural waterproofing.
    • Spills should not be allowed to sit for extended periods of time, clean all spills in a timely manner.
    • Make sure the most current versions of product data sheets and safety data sheets are being used.

    Coverage: 1 coat: 150 - 250 square feet per gallon. 2 coats: 75 - 125 square feet per gallon. Variations in texture and porosity of substrate will affect the coverage and performance of the product.
