DESCRIPTION: |
| DBA-5 is a two
component, 100% solids, rapid setting, non-abrasive,
high modulus epoxy gel. DBA-5 is designed for use with
meter mix pumping equipment or is packaged in
easy-to-use two component cartridges. DBA-5 is
color-coded to assure that mixing is complete. |
|
USES: |
| Grout for dowel bars,
rebars and anchor bofts in concrete for load bearing
applications.
Bonding hardened
concrete and other materials to hardened concrete.
Binder for epoxy
mortars.
Sealing cracks and
adhering ports for crack injection. |
|
ADVANTAGES: |
| Rapid set for early
strength.
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,
Class A, Type I, 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 scarifying 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-5 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. Check dispensing equipment to be
sure of correct 1:1 by volume mix ratio. Mixed products
should be a homogeneous gray color with no black or
white streaks.
If mixing DBA-5 by hand,
combine part A and part B in equal volumes. Do not mix
more than can applied in five (5) minutes.
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.
When used as a surface
sealer or adhering injection ports, apply with trowel or
spatula. Injection can commence once DBA-5 is
sufficiently cured.
For epoxy mortar, mix 1
volume of clean, dry sand to 1 volume of mixed DBA-5.
Apply by trowel to prepared substrate. |
|
LIMITATIONS: |
| Do NOT apply when
temperature is below 33°F.
Do NOT apply to latex
modified mortar or concrete. |

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