DESCRIPTION
|
Corro-Dur
192 was formulated to provide safe and effective
sealing and reinforcement of surfaces such as concrete exposed
to contamination from road salts, gasoline, oil drips and similar
materials. The unique Corro-Dur 192
formulation has excellent tolerance to the dampness left in
concrete after preparation for coating by high pressure water
jetting . The formulation is solvent-free to avoid the objectionable
odor and explosion hazards of epoxy solvents. Absence of solvents
also assures compliance with all present and proposed air pollution
regulations. Corro-Dur 192
is non-blushing and can be applied and will cure underwater.

USES
|
| SURFACE
REINFORCEMENT |
An ideal binder for making
concrete repair mortar. A standard 2 gallons (7.5 liters)
kit of Corro-Dur 192
will accept 2 gallons (7.5 liters) of sand filler to yield
4 gallons (15 liters) of a 'self leveling' filler or up
to 3 gallons (11 liters) of sand filler to yield 5 gallons
(18.75 liters) of a trowelable mortar.
|
| REINFORCEMENT |
Used extensively in glass
reinforced epoxy systems especially for application such
as underwater hull repair and custom GRP fabrications. The
long potlife, predictable cure rate and total absence of
surface 'blush' together with excellent physical and chemical
resistance make Corro-Dur 192
ideal for applications exposed to harsh industrial or marine
conditions. Because of the chemical curing process and relatively
gentle exotherm, unlimited applications may be made at one
time.
|
| SEALER |
When used as a sealer Corro-Dur
192 is designed to be absorbed into the concrete
surface, very heavy applications will result in a glossy,
slippery film which can be made skid resistant by broadcasting
sand into it while still liquid..

SURFACE PREPARATION
|
Remove surface contamination by high pressure water jetting
or similar methods with or without abrasive injection. Hand
held power tools such as grinders or needle guns will give good
results if applied conscientiously in small areas but will be
inadequate in large areas. Conventional abrasive blasting using
air/abrasive or centrifugal blasters are preferred methods of
surface preparation in most cases where oily or greasy contamination
is a problem.
|
|
APPLICATION
|
Mix CORRO-DUR 192 epoxy base
(in the partly filled two gallon pail) with the CORRO-DUR
192 curing agent supplied in the partly filled one
gallon can. Use a mechanical mixer if possible to ensure thorough
mixing. The mixing ratio is 3/2 (base/curing agent) by volume.
CORRO-DUR 192 does not require
a 'sweat-in' an induction time and the mixed components should
be used immediately.
Potlife is approximately 40 minutes at 77°F (27°C), small amounts
of solvent may be added if the mixture begins to thicken noticeably
towards the end of its working life. Apply in a thin film using
a brush, roller, pad or squeegee. Overcoating with CORRO-DUR
materials may be carried out before full curing of the CORRO-SEAL
192 if necessary since chemical curing will continue normally
even when overcoated.
If using CORRO-DUR
192 as a mortar begin by thoroughly mixing the CORRO-DUR
base and curing agent in a 5 gallon (19 liters) pail. Then gradually
blend in the sand using a 'Jiffy' type mixer.

|
TEMPERATURE
|
Temperature exerts a considerable influence on the rate of hardening
of chemically cured materials such as CORRO-DUR
192. In broad terms expect each 10°C, (18°F), rise
or fall temperature to half or double dry times and pot lives.
