4.
Turn the material and catalyst valves to the Injection
position.
5.
Depress the air switch button on the gun head to
dispense mixed material.
It’s strongly recommended
at this time to do a couple of test shots in a suitable
cup to confirm proper gel time.
When starting a new machine, it is recommended to
dispense a couple of strokes of resin into a suitable
container to ensure a proper flow of materials. This is
not required once the machine has been properly
wet-out.
6.
When finished, turn catalyst & resin valves
on the gun head to recirculation position.

7.
Flush the system.
a. Press the Air Flush button.
b. Press the Solvent Flush button.
c. Press the Air Flush button again.
8.
Assure that proper catalyzation was achieved.
THE CATALYST PUMP WILL
THEN MOVE TO THE SELECTED
POSITION.

Isocyanate Conditions
Material Self-ignition
Moisture Sensitivity of
Isocyanites
Isocyanites (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 performance and the life of all wetted parts.
To prevent exposing ISO to moisture:
•
Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere.
Never
store ISO in an open container.
•
Keep the ISO lube pump reservoir (if installed) 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 containers closed
when not in use.
•
Never use solvent on one side if it has been contam-
inated from the other side.
• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.

Foam Resins with 245 fa
Blowing Agents
Some foam blowing agents will froth at temperatures
above 90°F (33°C) when not under pressure, especially
if agitated. To reduce frothing, minimize preheating in a
circulation system.
Spraying materials containing isocyanates creates
potentially harmful mists, vapors, and atomized partic-
ulates.
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 providing sufficient ventila-
tion in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate per-
sonal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
The amount of film formation and rate of crystalli-
zation varies depending on the blend of ISO, the
humidity, and the temperature.
NOTICE
To prevent cross-contamination of the equipment’s
wetted parts,
never interchange component A (isocy-
anate) and component B (resin) parts.
Start-Up
When making test material dispenses or during flush -
ing operation, make certain that dispensed material
and/or solvent is contained in a suitable container and
that this material and/or solvent is disposed of prop-
erly.
Changing Materials
22 Rev. G 6/17/2008
Changing Materials
• When changing materials, flush the equipment mul-
tiple times to ensure it is thoroughly 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 (hardener)
side. Polyureas often have amines on the B (resin)
side.
Splatter Hazard
This section is used with some RAM plates which could get pushed out of the drums of sealant.
Burn Hazard
For equipment used with heated material.
WARNING
SPLATTER HAZARD
Hot or toxic fluid can cause serious injury if splashed in the eyes or on skin. During blow off of platen,
splatter may occur.
•
Use minimum air pressure when removing platen from drum.
WARNING
BURN HAZARD - Hot Surfaces
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe burns:
• Do not touch hot fluid or equipment.
•
Wait until equipment/fluid has cooled completely.
