Dowel Bar Adhesives - #DBAL30

Item # DBAL30, High Modulus, Pourable, Epoxy Adhesive

DBA-L30 is a two component, 100% solids, moisture tolerant, high modulus epoxy adhesive supplied in easy-to-mix 1:1 by volume ratio.

 

Uses

  • Grout for dowel bars, rebars and anchor bolts in concrete for load bearing applications.
  • Bonding hardened concrete and other materials to hardened concrete.
  • Binder for epoxy mortars.

Advantages

  • Moisture insensitive - may be applied to dry or damp concrete or in humid conditions.
  • Color-coded for error-free mixing.
  • 100% solids, conforms to VOC regulations.
  • Conforms to Grade 2, Classes B&C, Type IV, & V of ASTM C-881.
  • Non-abrasive.

Surface Preparation

All concrete surfaces to be bonded should be dry for best results. However, a damp surface dry condition is acceptable. Surfaces must be free of standing water. Mechanical scarifing to remove laitance or other foreign materials will result in optimum bond. Drill holes must be air blasted to remove residual dust. Steel dowel bars must be free of rust and oily substances. Sand blast or wire brush to white metal.

 

Mixing & Application

DBA-L30 supplied in containers should be inspected for settling. The individual components should be mixed prior to combining them or charging them into the compartments of dispensing equipment. Mix thoroughly, 1 part by volume, component A with component B. Mixed product should be a homogeneous gray color with no black or white streaks. Do not mix more than can be applied in 30 minutes at 77 °F.

 

Inject dowel hole to half its depth with mixed epoxy. Insert the dowel bar with a twisting motion to coat the bar and then push it to the bottom of the hole. Use only enough material to cause a slight run off to the face of the hole when the dowel or anchor has been placed.

 

For epoxy mortar, mix 1 volume of clean, dry sand to 1 volume of mixed DBA-L30. Apply by trowel to prepared substrate.

 

Limitations

  • Do NOT apply when temperature is below 45°F.
  • Do NOT apply to latex modified mortar or concrete.

Clean Up

Clean tools and equipment immediately with a suitable solvent such as xylene or lacquer thinner.

 

Caution

For professional use only. Epoxy systems can cause delayed dermatitis. Avoid prolonged contact with skin. See Material Safety Data Sheet for proper handling and required safety equipment.
