Applications & Uses
- Markets
- Application Method
- Uses
- Adhesive for bonding external reinforcement to concrete, masonry, wood, stone, steel, etc.
- Structural bonding of QuakeWrap®, PipeMedic®, PileMedic® and SpiRe products.
- Structural bonding on vertical and overhead surfaces.
- Coverage
Surface Application:
- Applied at a thickness of 40 mil results in 40 square feet per gallon (1 liter per square meter).
- Rough and uneven surfaces result in lower yields.
Laminate Application:
Applied at a thickness of 20mil results in 80 square feet per gallon (0.5 liters per square meter).
- Application Equipment
Use a putty knife or notched trowel for smoothing of resin.
- Surface Preparation
For Bond-Critical Applications:
Surfaces must be entirely free of oil, grease, dirt, detergent, laitance, curing compounds, coatings, or other contaminants that may interfere with adhesion.
Steel:
- Immersion Service: SSPC-SP10 Near White Blast Cleaning with 3.0 mil profile.
- Non-Immersion Service: SSPC-SP6 - Commercial Blast Cleaning with 2.0 mil profile.
Concrete:
- Concrete shall be properly cured and no longer outgassing before application.
- Final prepared surface should be clean and rough.
- The concrete surface should be prepared to a minimum concrete surface profile (CSP) 2 as defined by the ICRI surface-profile chips.
- Mixing
- Prior to mixing, all products should be preconditioned to room temperature (65-85°F / 18-29°C).
- Portion out 2 components by weight.
- Pour Part B into a container with Part A, mix for at least 2 minutes.
- Do not mix more material than can be applied within the pot life.
- Begin application immediately.
3gallon kit:
- Pour Part B hardener into Part A resin.
- Hand mix for 3 minutes, scraping sides and bottom of the container to ensure complete mixing.
- Do not hand mix.
- Application
- Air and surface temperature should be between 45-95°F (7-35°C).
- Do not begin application if air, substrate, or material temperatures is below 45°F (7°C) or expected to fall below 45°F (7°C) within 24 hours of application.
- Do not begin application if the dew point is within 5°F (3°C) of the temperature.
- Temperature variations can affect the pot life and sag properties of this material.
- Apply product to substrate with a putty knife or trowel and smooth to appropriate thickness.
- Cleanup
Collect with absorbent material, clean up using acetone or other ketone solvents.
- Limitations
- QuakeBond™ 220TC will not cure in temperatures below 40°F.
- Seek approval from a QuakeWrap representative for applications of the product below 45°F.
- All epoxies will show chalking/yellowing on exterior exposures.
- Application of epoxy coatings in cool temperatures and high humidity can result in the formation of amine blush.
- Blush may appear as a milky, white, tacky residue on the surface of the cured coating and must be removed before the application of another coat.
- Intercoat adhesion problems may occur if blush is not removed.
