APPLICATIONS FOR
F9911 EPDM RUBBER SEALANT |
|
|
|
F9911 EPDM Rubber Sealant is a two-component
product, which has a thixotropic consistency to permit
application to surfaces of any orientation. The most
effective method of application is by trowel on a flat
surface and a stiff brush for irregular surfaces.
F9911 EPDM Rubber Sealant can be used for lining
steel process tanks, creating a formed-in-place reinforced
rubber membrane for concrete tanks and ponds, as well as for
creating gaskets for specialized process tanks. |

|
SURFACE PREPARATION |
|
Surface must be clean and dry. Sealant will not adhere to a
damp surface, glass or polyethylene and thermoplastic
olefins. Smooth metal surfaces must be abraded to create a
surface profile for adhesion. |

|
|
APPLICATION |
The pre-measured catalyst supplied must be added to the
product prior to application. Catalyzed material can be
poured onto surface and distributed with a trowel. Multiple
passes are recommended in order to eliminate air
entrainment.
A two-coat application is recommended. Each coat should be
spread at a rate of 50 sq. ft. per gallon, which will result
in a dry film of 20 mils. The solvent vapors are heavier
than air, so fans or forced air should be used in enclosed
areas to purge the vapors and speed the cure. (Do not use
outside air if temperature is below 65°F). Apply a second
coat the following day using the same procedure as outlined
above. Resulting dry film will be 40 mils. |

CREATING A FORMED - IN - PLACE MEMBRANE |
Apply first coat of F9911 EPDM Rubber Sealant
as described above and allow solvent to flash off for
approximately 6 hours. Use ventilation to remove vapors.
Cut polyester reinforcing fabric to desired length and place
on tacky rubber surface. Lightly roll fabric with a smooth
sponge roller to get even contact with the rubber. Let stand
overnight. Note: When coating a tank or an enclosure, apply
the rubber and fabric to the walls and several inches of the
floor on the first pass. Apply the second coat (at 50 sq.
ft. per gallon) no later than the following day, coating
over the reinforcing fabric and continuing with what will
now be the first coat on the floor. The reinforcing fabric
must be put in place in as the coating process progresses to
avoid having to walk on the wet rubber. A small area (where
ladder rests) will have to be left without fabric and coated
from above using a long handled squeegee. Continue to use
ventilation.
Apply a second coat to floor 24-36 hours after the first
coat. The first coat should be firm enough to walk on by
then. A rubber edged squeegee will be easier to use than a
trowel for the second coat. A reinforced membrane will be 45
mils when recommended spreading rates are used. |

CURE |
|
Allow 4 days of cure at 70°F or higher before putting
coating into service. Heat will accelerate the curing
process.
