DESCRIPTION
|
CORRO-DUR
258 is formulated
for effective field application by brush, roller or plural
component heated airless sprayer. The CORRO-DUR
258 formulation is based on a unique resin system
which may be applied to damp or wet surfaces. This resin system
is toughened with * Kevlar™ fibers to give superior chip
resistance and is pigmented with select hard ingredients to
further enhance wear resistance.
The cured film is glossy with a slight texture resulting from
the fiber reinforcement. Related products have been employed
for underwater application and have been subjected to both
radiation and DBA testing with excellent results. The resin
system used has excellent resistance to commodities such as
hydrocarbon oils and fuels, mineral acids and alkalies.
The solvent - free formulation
avoids the objectionable odor and explosion hazards of epoxy
solvents. Absence of solvent also assures compliance with
all present and proposed air pollution regulations and prevent
common service problems caused by shrinkage or water sensitivity
of residual entrained solvent residues.

SURFACE
PREPARATION
|
| STEEL |
For heavy duty
applications it is always preferable to abrasive blast in
order to assure maximum performance. CORRO-DUR
258 is extremely tolerant of compromised surface
preparation where tight rust of existing coating residues
must be overcoat. The solvent- free formula of CORRO-DUR
258 allows applications
over existing coatings without softening or swelling, in
fact, even Styrofoam TM may be successfully coated with
this material. To ensure adhesion over means to provide
an anchor profile.
|
| CONCRETE |
New surfaces
must be abrasive blasted or acid etched to remove the superficial
layer of laitance. Treat existing coatings as for steel.
|
| UNDERWATER
SURFACE |
Abrasive blast
to remove marine growth and corrosion then apply by roller
within 45 minutes of surface preparation |
|
|
APPLICATION
|
CORRO-DUR
258 is supplied in
two gallon (7.6 Liters) units. 1.33 gallons (liters) of epoxy
base are filled into a two gallon plastic pail and 0.67 gallons
(2.51) of curing agent are filled into a one gallon steel
can to yield a 2/1 mixing ratio. Stir the curing agent into
the base preferably using a mechanical mixer. Once mixing
is complete, start application immediately -
CORRO-DUR 258 does not required a "sweat-in" or
induction time. Pot life is about 30 minutes at 77°F (25°C),
small amounts of epoxy solvent may be added if the mixture
begins to thicken noticeably towards the end of its working
life. Apply CORRO-DUR 258
using brush or roller. Underwater application is best made
using rollers or paint pads after surface preparation by air
abrasive or high pressure water blasting to remove loose surface
contamination and marine biological fouling.

|
TEMPERATURE
|
Temperature will exert a considerable
influence on the rate of curing chemically cured coatings
such as CORRO-DUR 258.
In broad terms expect each 10°C, (18°F), rise or fall in temperature
to half or double dry times and pot lives.
