There are several applications where ACRASTRIP can be used. The highest volume area being the paint line purge. This will require testing and a few programming changes. These tests and changes to the process can often take time. It is recommended while these changes/tests are being made that some of the easier solvent replacement procedures be trailed.
Clean-up/Wipe-up
Requires
a saturated
rag of
the solution
with areas
identified
as typical
tasks
by the
user.
This may
include
wiping
down guns,
hoses
and other
paint-laden
substrates.
ACRASTRIP
also works
very well
on wiping
down glass
windows
and doors
in a paint
booth.
(Recommended
dilution
2 parts
water,
1 part
ACRASTRIP)
Paint
Stripping
When
the paint
is actually
dried
on/cured,
it usually
requires
full immersion
of that
part in
the ACRASTRIP.
The solution
should
be made
at 1-1
with water.
Fast acting
stripping
will take
place
when you
heat the
solution
to 150-165
degrees
F. Longer
soak times
will enable
you to
use the
solution
at ambient
temperatures.
Especially
in 2K
coatings
applications,
parts
integral
to plural
component
metering
systems
(Valves,
integrators,
meters,
Etc.)
can be
immersed
in the
ACRASTRIP
and revitalized
quite
readily.
ACRASTRIP
can also
be used
to strip
re-work,
booth
grates,
hooks,
racks,
and jigs
replacing
off-site
burn-off
applications
in many
cases.
(Dilute
the ACRASTRIP
1-1 for
the stripping
applications)
Test
Procedure
Add
2 gallons
of ACRASTRIP
and two
gallons
of water
to a clean
5 gallon
pail.
(For acceleration,
it is
recommended
that you
heat the
solution
to 150
degrees
F) Submerge
a few
test parts
in the
solution,
checking
them every
15 minutes.
It may
require
an air
blast
or some
other
mechanical
activity
to thoroughly
remove
the coating.
(ACRASTRIP
is available
in jell
form for
stripping
vertical
surfaces!)
Gun
Cleaning
ACRASTRIP
works
very well
in gun
washing
systems
as well
as manual
cup gun
cleaning
applications.
It is
recommended
in a gun
washing
system
that a
screen,
filter,
or strainer
be added
to the
suction
side of
the pump.
(Use at
1-1 with
water,
ambient
temperatures)
Pump
Flushing
In
most applications,
the ACRASTRIP
can be
used at
10-20%
solution
strengths
for this
application.
(10% if
heated
to 140
degrees
F, 20%
if used
at ambient
temperatures)
Procedure
Wipe off
the in-take/suction
tube of
the pump,
remove
all filter
media,
submerge
the tube
in an
ample
supply
of the
diluted
ACRASTRIP
solution
and flush
the pump
at no
less than
65 PSI.
Ideally,
an air
purge
should
follow
into the
paint
line when
possible.
This will
insure
total
evacuation
of the
solution
prior
to charging
the line
with the
next coating.
Occasionally
you may
run into
a system
that is
"locked
up" due
to poor
maintenance,
Etc. In
this application,
use the
ACRASTRIP
at 1-1
with water,
heated
to 160
degrees
F. Continually
circulate
the solution
through
the pump
and line,
filtering
the hardened
paint
through
a bag
filter
at the
discharge.
