DESCRIPTION: |
| DBA-30 is a
two component, 100% solids, nonabrasive, high modulus
epoxy gel. DBA-30 is supplied in easy-to-mix 1:1 by
volume ratio and is color-coded to assure that mixing Ls
complete. DBA-30 exhibits superior adhesion to both
concrete and steel. |
|
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 3,
Classes B&C, Type 1, 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
AND APPLICATION: |
|
DBA-30
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-30. 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. |
