DESCRIPTION: |
| 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. Binder for epoxy mortar systems for
filling keyways or joints between prestressed concrete
members.
Bonding hardened
concrete and other materials to hardened concrete.
Injection of wet or
underwater cracks. |
|
ADVANTAGES: |
| Moisture insensitive.
100% solids, conforms to
VOC regulations. Easy-to-use 1:1 by volume mix ratio.
Conforms to ASTM C-881,
Grade 2, Class B&C, Type IV, & V. |
|
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: |
| Combine part A and part
B in equal volumes in a suitable clean container and mix
with a low speed mixer for 2-3 minutes until thoroughly
blended. The sides and bottom of the mix container
should be scraped frequently to ensure complete mixing.
To prepare mortar, use
clean, dry bagged silica sand. Mix 3-5 parts by volume
of sand to 1 volume of mixed epoxy. Prime surface to
receive mortar with neat epoxy. Place mortar with a
spatula or trowel. DBA-L30 can be injected into cracked
concrete using a two component, positive displacement
injection machine. Set mix ratio to 1:1 by volume.
DBA-L30 may be hand mixed and poured into large cracks
for horizontal repairs. |

LIMITATIONS: |
| Do NOT apply when
temperature is below 40°F.
Do NOT apply to latex
modified mortar or concrete. |
