DESCRIPTION
|
CORRO-DUR 197
is a premium quality low viscosity epoxy resin designed for
engineering applications where excellent physical and mechanical
properties are required in difficult application environments
The formulation is solvent-free to avoid the objectionable odor
and explosion hazards of epoxy solvents and assures compliance
with all present and proposed air pollution regulations. The
low viscosity of the mixture is achieved through the use of
low molecular weight liquid epoxy resin modified with a reactive
diluant resin in order to yield a permanently tough and stable
cured product.

USES
|
| SEALANT
|
Seals surface from water,
oil, grease and other materials.

| SURFACE
REINFORCEMENT |
CORRO-DUR
197 may be filled
with a variety of mineral aggregates in order to yield desired
properties. By varying the type and quantity of aggregate
is possible to obtain desired properties such as chemical
and physical resistance and viscosities from an easily pourable
liquid to a stiff grout. CORRO-DUR
197 with selected aggregate will bond to wet
or damp surfaces and is especially useful for sealing or
grouting in wet environments. CORRO-DUR
197 based grouts or mortars cure at the same
rate whether applied on wet or dry surfaces.
|
| FLOORING
SYSTEM |
CORRO-DUR
197 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
|
| MARINE
EPOXY |
CORRO-DUR
197 seals hull, piers and pilings, etc. from
water absorption & can also be pre-pregnated with woven
fiberglass cloth to achieve a composite sleeve for rebuilding
of corroded pipelines. It can be top-coated with any anti-fouling
paint

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 197 epoxy base
(in the partly filled two gallon pail) with the CORRO-DUR
197 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 197 does not require
a 'sweat-in' an induction time and the mixed components should
be used immediately.
Potlife is approximately 55 minutes at 77°F (25°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
197 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
197. In broad terms expect each 10°C, (18°F), rise
or fall temperature to half or double dry times and pot lives.
