ClearShot Liquid
10 312666F
ClearShot Liquid
Isocyanate Hazard
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two
component foam and polyurea coatings. ISO
will react with moisture (such as humidity) to
form small, hard, abrasive crystals, which
become suspended in the fluid. Eventually a
film will form on the surface and the ISO will
begin to gel, increasing in viscosity. If used,
this partially cured ISO will reduce perfor-
mance and the life of all wetted parts.
To prevent exposing ISO to moisture:
• Always use a sealed container with a desic-
cant dryer in the vent, or a nitrogen atmo-
sphere. Never store ISO in an open
container.
• Keep the ISO lube pump reservoir filled
with Graco Throat Seal Liquid (TSL), Part
206995. The lubricant creates a barrier
between the ISO and the atmosphere.
• Use moisture-proof hoses specifically
designed for ISO, such as those supplied
with your system.
• Never use reclaimed solvents, which may
contain moisture. Always keep solvent con-
tainers closed when not in use.
• Never use solvent on one side if it has been
contaminated from the other side.
• Always park pumps when you shutdown.
• Always lubricate threaded parts with Part
217374 ISO pump oil or grease when reas-
sembling.
Read material MSDS to know specific haz-
ards and precautions related to ClearShot
Liquid.
Spraying materials containing isocyanates
creates potentially harmful mists, vapors,
and atomized particulates.
Read material manufacturer’s warnings and
material MSDS to know specific hazards and
precautions related to isocyanates.
Prevent inhalation of isocyanate mists,
vapors, and atomized particulates by provid-
ing sufficient ventilation in the work area. If
sufficient ventilation is not available, a sup-
plied-air respirator is required for everyone in
the work area.
To prevent contact with isocyanates, appro-
priate personal protective equipment, includ-
ing chemically impermeable gloves, boots,
aprons, and goggles, is also required for
everyone in the work area.
The amount of film formation and rate of
crystallization varies depending on the
blend of ISO, the humidity, and the tem-
perature.

Keep Components A and B Separate
312666F 11
Keep Components A
and B Separate
Foam Resins with 245
fa Blowing Agents
New foam blowing agents will froth at tempera-
tures above 90°F (33°C) when not under pres-
sure, especially if agitated. To reduce frothing,
minimize preheating in a circulation system.
Changing Materials
• When changing materials, flush the equip-
ment multiple times to ensure it is thor-
oughly clean.
• Always clean the fluid inlet strainers after
flushing.
• Check with your material manufacturer for
chemical compatibility.
• Most materials use ISO on the A side, but
some use ISO on the B side.
• Epoxies often have amines on the B (hard-
ener) side. Polyureas often have amines on
the B (resin) side.
CAUTION
To prevent cross-contamination of the equip-
ment’s wetted parts, never interchange com-
ponent A (isocyanate) and component B
(resin) parts. The gun is shipped with the A
side on the left. The fluid manifold, fluid
housing, side seal assembly, check valve
cartridge, and mix chamber are marked on
the A side.

Grounding
12 312666F
Grounding
Check your local electrical code and propor-
tioner manual for detailed grounding instruc-
tions.

Fluid in the hose and proportioner is still under
pressure. Follow the Pressure Relief Procedure
in the proportioner manual.
To relieve pressure in the hose manifold after the
gun is removed, place the fluid manifold over
containers, facing away from you. Ensure fluid
valves are closed. Very slowly open fluid mani-
fold check valves 2 to 2-1/2 turn. Under high
pressure, fluid will spray sideways from the fluid
ports.
