CHEM-ANCHOR

Two-component, 100% Solid Epoxy Anchoring Adhesive

CHEM-ANCHOR is a two compo­nent, 100% solids, high strength, epoxy gel adhesive designed to anchor dowel bars, bolts and pins into concrete. This product meets ASTM C881, Type I, IV, V, Grade 3, Class A. CHEM-ANCHOR is a non-abrasive flowable epoxy adhesive designed for applications into vertical holes drilled in concrete for setting of dowel rods, re-bars, bolts, pins etc. It is used in highway or airport runway slabs. CHEM-ANCHOR is a structural adhesive also applicable for bonding of: Concrete to concrete, Glass to wood, Aluminum to Aluminum and any other combination of similar or dissimilar construction materials. The fast setting adhesive may be mixed and applied by hand, machine, or caulking gun into the drilled holes.

APPLICATION

Limitations:  Applications at ambient temperatures below 41°F (5°C) is not recommended.

 

Pre-treatment of Substrate:

 

Concrete Surfaces: The surface or holes must be clean, dry, free from grease or oil, etc.   Laitance and loose particles must be removed by either sandblasting or mechanical grinding. Holes must be cleaned using dry and oil free compressed air.

 

Steel Surfaces: All steel surfaces to be bonded with CHEM-ANCHOR must be clean, dry, free from rust, oil, grease, etc. Shot blasting to Swedish Standard SA 2 ½ is preferable to achieve a white metal finish prior to application.

 

Holes for Setting Dowels:

 

Holes Dimensions: The annular space between anchor rod, dowel, rebar, etc., and hole should be as small as possible 3 to 5 mm yet still provide ease of placement.

 

Depth of Embedment Guidelines:

  •  When substrate has compressive strength of 3046 psi (21 N/mm²) and greater or the anchor bolts are threaded, the minimum depth is 10 times the bolt diameter.
  • For grouting smooth bolts or into substrates with less than 3046 psi (21 N/mm²), the minimum depth of embedment is at least 15 times the bolt diameter

 

Drilling:

  • Dry Drilling: Vacuum or blow out the dust from hole using oil free compressed air or blow pump
  • Wet Drilling: Wash out hole with clean water to remove residue of drilling slurry. Remove free standing water. It is preferable to allow the hole to complete dry.
  • Bolts, dowels, rebars must be clean de-rust, dry and de-grease.

 

Mixing:  Stir each component separately. Mix one part A and one part B by volume into a clean mixing container. Mix the epoxy with a slow speed electric drill fitted with a mixing paddle attachment. Carefully scrape the sides and bottom of the pail during mixing. Blend for 3 minutes. Large batches of epoxy will cure much faster than small batches. Mixed epoxy will cure much faster in hot weather than in cold weather. This mixing is not required for product applied using dual cartridge.

 

Application: Application can be made by mechanical, pneumatic dosage equipment, caulking guns or by hand. Force the mixture into drilled hole then insert the steel bar with a twisting motion to ensure intimate contact and a good bond without air entrapment, lightly tap the anchor dowel to ensure complete embedment. Wipe off any excess material from the surface and finish to a neat smooth surface.

 

Bonding of any similar/dissimilar material: Ensure both surfaces to bond is clean and free of dust, oil, grease, etc. Roughen up the surfaces for good mechanical keying. Apply in thin layer CHEM-ANCHOR on both surfaces. Pull them together and hold into position undisturbed for 6 – 8 hours.

 

Curing: Initial setting is minimum 8 hours. Full cure is 3 days.

 

Cleaning: remove uncured CHEM-ANCHOR from tools and equipment with suitable solvents such as Xylene, Toluene or CHEM-CRETE BLENDED SOLVENT immediately after use. Cured material may only be removed mechanically.

STORAGE

The product can be stored for minimum of twelve months at temperature from 50°F to 95°F (10°C to 35°C) in the unopened original packaging.  Protect from direct sunlight.

SAFETY

After hardening thoroughly, CHEM-ANCHOR is physiologically harmless. Keep the resin and hardener away from the eyes mouth and skin.  Do not breathe in the vapors.  The uncured mixture can cause irritation of the skin.  For best protection, wear rubber or plastic gloves.  In case of contamination, wipe away resin or hardener immediately from the skin using paper towels and then wash with soap and water or hand cleaning detergent. Empty resin and hardener cans must be disposed according to local city code or regulations.   Under no circumstances empty cans should be used to store food or drink even if they have been thoroughly cleaned. Follow all cautionary direction as printed on container’s labels.
