DESCRIPTION
|
CORRO-CHEM 330
is designed for applications where resistance to aggressive
chemical exposure is of paramount importance. The sophisticated
resin formula has excellent resistance to acids, acid fumes
and a wide variety of solvents.
CORRO-CHEM 330 cures to
a very tough, abrasion and impact resistant film. Use as a hopper
car lining exposed to impact, abrasion and chemical fumes is
particularly recommended.
The high heat resistance of CORRO-CHEM
330 makes it very attractive for down-hole applications
exposed to high ambient temperatures and hydrocarbons up to
a maximum of 149°C.
Application is by airless spray
with easy touch up by brush or roller.

USES
|
DOWN-HOLE TUBULAR COATING :
ID and OD coating, especially
suitable for “Ruffcoat” OD treatment.
TANK LINING :
High hydrocarbon chemical resistance and early return to service
make CORRO-CHEM 330 an ideal high build tank lining.
HOPPER CAR LINING : Excellent
physical and chemical resistance properties.

SURFACE PREPARATION
|
Surface must be free of oil, grease,
dirt etc. For steel in atmospheric service an SSPC-SP-6 Commercial
blast will be the ideal standard of surface preparation. However,
surface prepared to SSPC SP3 area needs to be primed by Corro-Dur
258 / Corro-Dur 192 / Corro-Dur 257.
Steel :
For steel in immersion service
an SSPC-SP-5 “white metal” blast standard is required. An angular
surface profile of 2 – 3 mils, (50 – 75 microns), is recommended.
Concrete :
Concrete is best prepared by brush blasting at a reduced pressure
in order to yield a “medium sandpaper” texture free of gross
surface deposits or contamination

|
MIXING PROCEDURE
|
CORRO-CHEM 330 is supplied
in 10-gallon kits of two 5-gallon containers of epoxy base and
curing agent respectively. When applied premixed the components
must be intimately mixed before application taking special care
to incorporate components from the walls and base of the mixing
vessels.
Note: unmixed components will never cure.
