Important Two-Component Material Information
Important Two-Component Material Information
Isocyanate Conditions
Keep Components A and B
Separate
Spraying or dispensing materials containing
isocyanates creates potentially harmful
mists, vapors, and atomized particulates.
Cross-contamination can result in cured
material in fluid lines which could cause serious injury or damage equipment. To prevent
cross-contamination of the equipment’s wetted parts, never interchange component A
(isocyanate) and component B (resin) parts.
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 ventilation 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 personal protective equipment,
including chemically impermeable gloves,
boots, aprons, and goggles, is also required
for everyone in the work area.
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 performance and the life of all wetted parts.
The amount of film formation and rate of
crystallization varies depending on the
blend of ISO, the humidity, and the temperature.
Material Self-ignition
To prevent exposing ISO to moisture:
Some materials may become self-igniting if
applied too thickly. Read material manufacturer’s warnings and material MSDS.
•
•
12
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.
312062W
Important Two-Component Material Information
•
•
•
•
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 contaminated 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.
312062W
Changing Materials
•
When changing materials, flush the equipment multiple 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.

pressure setting. The A and B temperatures can be offset to help balance the fluid
pressure.
•
Mix chamber size. Choice of mix chamber
is based on desired flow rate and fluid viscosity.
•
Clean-off air adjustment. Too little
clean-off air results in droplets building up
on the front of the nozzle, and no pattern
containment to control overspray. Too
much clean-off air results in air-assisted
atomization and excessive overspray.

Setup
Setup
NOTICE
Proper system setup, start up, and shutdown
procedures are critical to electrical equipment reliability. The following procedures
ensure steady voltage. Failure to follow these
procedures will cause voltage fluctuations
that can damage electrical equipment and
void the warranty.
2. General equipment guidelines
•
1. Locate Reactor
Use the following procedure to determine
the correct size generator.
a. Locate Reactor on a level surface. See
Dimensions, page 48, for clearance
and mounting hole dimensions.
a. List system components that use peak
load requirements in watts.
b. Do not expose Reactor to rain.
b. Add the wattage required by the system
components.
NOTICE
To prevent damage from tipping over and falling, proper care needs to be taken when lifting the Reactor. Bolt Reactor to original
shipping pallet, to keep stable, before lifting.
c. Use the casters to move Reactor to a
fixed location, or bolt to shipping pallet
and move with forklift.
c. Perform the following equation:
Total watts x 1.25 = kVA (kilovolt-amperes)
d. Select a generator size that is equal to
or greater than the determined kVA.
•
Use proportioner power cords that meet or
exceed the requirements listed in Table 2.
Failure to do so will cause voltage fluctuations that can damage electrical equipment.
•
Use an air compressor with constant speed
head unloading devices. Direct online air
compressors that start and stop during a
job will cause voltage fluctuations that can
damage electrical equipment.
d. To mount on a truck bed or trailer,
remove casters and bolt directly to truck
or trailer bed. See page 48.
312062W
Determine the correct size generator.
Using the correct size generator and proper
air compressor will enable the proportioner
to run at a nearly constant RPM. Failure to
do so will cause voltage fluctuations that
can damage electrical equipment. Ensure
the generator matches the voltage and
phase of the proportioner.
23
Setup
•
Maintain and inspect the generator, air
compressor, and other equipment per the
manufacturer recommendations to avoid
an unexpected shutdown. Unexpected
equipment shutdown will cause voltage
fluctuations that can damage electrical
equipment.
•
Table 1:
Electrical Requirements
(kW/Full Load Amps)
Use a wall power supply with enough current to meet system requirements. Failure
to do so will cause voltage fluctuations that
can damage electrical equipment.
3. Electrical requirements
See Table 1.
Installing this equipment requires access to
parts which may cause electric shock or
other serious injury if work is not performed
properly. Have a qualified electrician connect
power and ground to main power switch terminals, see page 25. Be sure your installation complies with all National, State and
Local safety and fire codes.

Pump Lubrication System
Important: The return tube (RT) must
reach the bottom of the reservoir, to
ensure that isocyanate crystals will settle to the bottom and not be siphoned
into the supply tube (ST) and returned
to the pump.
Check the condition of the ISO pump lubricant
daily. Change the lubricant if it becomes a gel,
its color darkens, or it becomes diluted with
isocyanate.
Gel formation is due to moisture absorption by
the pump lubricant. The interval between
changes depends on the environment in which
the equipment is operating. The pump lubrication system minimizes exposure to moisture,
but some contamination is still possible.
8. The lubrication system is ready for operation. No priming is required.
ST
RT
Lubricant discoloration is due to continual
seepage of small amounts of isocyanate past
the pump packings during operation. If the
packings are operating properly, lubricant
replacement due to discoloration should not be
necessary more often than every 3 or 4 weeks.
