Application

Surface Preparation:

All bonding surfaces must be clean and structurally sound. Remove oil, grease, laitance, dirt, and contaminants by mechanical means such as sandblasting or hydroblasting. Clean drilled holes with a nylon brush and oil-free compressed air. Ensure bolts, rebar, or threaded rod are clean.

Mixing:

Precondition cartridges to 75°F. For cartridges, material is mixed via a static mixing nozzle. Dispense until a uniform grey color (no streaks) is achieved.

Anchoring:

  • Hole depth = ~9x bolt diameter
  • Hole diameter = 1/8” larger than bolt diameter
  • Dispense from the bottom of the hole, filling approx. 5/8 of its depth
  • Insert anchor slowly, rotating for even distribution
  • Do not disturb until cured

Packaging

  • 22 oz. dual cartridge
  • 51 oz. dual cartridge
  • 10 gallon kits

Shelf Life

Two years when stored in original, unopened containers in clean, dry conditions. Avoid contamination with moisture or debris.

Coverage

Coverage depends on hole size and embedment depth. See pullout test data below for guidance on typical embedments.

Uses

  • Anchoring of bolts, dowels, and reinforcing steel
  • Structural bonding and patching in vertical or overhead positions
  • Suitable for concrete, block, brick, or stone installations
