DESCRIPTION: |
| SUPERIOR PATCH BINDER
is a two component low modulus, 100% solids epoxy
adhesive system designed for use as a binder for
patching and coating all concrete surfaces that are
exposed to stresses of impact or thermal change. Being
moisture insensitive, SUPERIOR PATCH BINDER may be used
on dry or wet surfaces. |
|
USES: |
|
Binder for patching
mortars. Injection repairs.
Binder for non-skid surfaces. Protective coating. |
|
ADVANTAGES: |
Low compressive modulus
- provides increased impact resistance and flexibility.
Easy-to-use 1:1 by volume mix
ratio. Moisture insensitive.
100% solids - conforms
to VOC regulations.
Conforms to ASTM C-881,
Type III, Grade 1, Class B & C. |
|
SURFACE
PREPARATION: |
| All surfaces to be
bonded, coated or repaired should be dry for best
results, however a damp, surface-dry condition is
acceptable. All concrete to be repaired must be free of
standing water. Smooth surfaces must be roughened by
sand blasting or acid etched with 5% muriatic acid
followed by thorough rinsing with clear water, or
mechanical scarification before the epoxy adhesive is
applied. The substrate must be clean and completely free
of oil, grease, other coatings and any other
contamination. |
|
MIXING
AND APPLICATION: |
Epoxy Mortar: The
individual components should be mixed prior to combining
them. Do not mix more material than can be applied in 40
minutes. Combine equal volumes of parts A and B in a
suitable mixing container and mix with a low speed mixer
until a uniform color is obtained. The sides and bottom
of the mix container should be scraped frequently to
ensure complete mixing. The Kol mixer is ideal for this
operation. Use clean, dry, bagged silica sand. Usually 3
to 3.5 gallons of sand per gallon of mixed epoxy will
yield the appropriate density for a trowelable system.
The receiving surface should be primed with the neat
epoxy mix prior to placing the mortar mix.
Injection Applications: SUPERIOR
PATCH BINDER may be injected into cracked concrete,
using two component cartridges, or a two component
positive displacement injection machine with the mix
ratio set at 1:1 by volume. It may also be hand mixed
and poured into large cracks for horizontal repairs.
Protective Skid
Resistant Coating: Mix components as described above for
epoxy mortars and spread onto the surface with squeegees
and back roll with a medium nap roller to distribute the
epoxy system at 10 mil thickness. Broadcast clean, dry
silica sand onto the applied epoxy system to obtain the
desired finish, or to excess H repeated applications are
required. In the latter case, the initial application
should be allowed to cure and the excess sand removed
before the surface is recoated with the mixed epoxy
system. |
|
LIMITATIONS: |
| Do NOT apply when
temperature is below 40°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. |
