311882T

Moisture Sensitivity of Isocyanates

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.

Isocyanate Hazard

Read material manufacturer’s warnings and material
MSDS to know the specific hazards of isocyanates.
Use equipment in a well-ventilated area. Wear
respirator, gloves, and protective clothing when using
isocyanates.

The amount of film formation and rate of
crystallization varies depending on the blend of
ISO, the humidity, and the temperature.
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.
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 Part 217374
ISO pump oil or grease when reassembling.

Foam Self-Ignition

Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
material MSDS.

Keep Components A and B
Separate
CAUTION
To prevent cross-contamination of the equipment’s
wetted parts, never interchange component A and
component B.

Changing Materials
•
•
•
•

When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
Check with your material manufacturer for chemical
compatibility.
Some materials use catalyst on the A side, but
some applications may use catalyst on the B side.
Epoxies often have amines on the B (catalyst) side.
Polyurethanes often have amines on the B (resin)
side.

Installation

Installation
Fluid Line Accessories
A bleed-type master air valve (D) and a fluid drain
valve (E) are required in your system, to help reduce
the risk of serious injury, including splashing fluid in
the eyes or on the skin, and injury from moving parts
when you are adjusting or repairing the pump.

A fluid drain valve (E) is required in your system to
relieve fluid pressure in the hose and gun (see the
WARNING on left). Install the drain valve so that it
points down and the handle points up when the valve is
opened.

The bleed-type master air valve (D) relieves air
trapped between this valve and the pump after the
pump is shut off. Trapped air can cause the pump to
cycle unexpectedly and result in serious injury,
including amputation. Install the valve close to the
pump.
The fluid drain valve (E) helps relieve pressure in the
displacement pump, hose, and dispensing valve
when shutting off the pump. Actuating the dispensing
valve to relieve pressure may not be sufficient, especially if there is a clog in the hose or the dispensing
valve.

System Accessories
To ensure maximum pump performance, be sure that all
accessories used are properly sized to meet your system’s requirements. See Accessories, page 20.

Air Line Accessories
Install the following accessories in the order shown in
the Typical Installation for Lubrication Applications,
using adapters as necessary:
An air line lubricator (B) provides automatic air motor
lubrication.
A bleed-type master air valve (D) is required in your
system to relieve air trapped between it and the air
motor when the valve is closed (see the WARNING on
left). Be sure the bleed valve is easily accessible from
the pump, and is located downstream from the air regulator.
An air line filter (C) to remove harmful dirt and moisture
from the compressed air supply.
A second bleed-type air valve (D) isolates the air line
accessories for servicing. Locate upstream from all
other air line accessories.

2. Place suction tube in grounded metal drum containing cleaning fluid.

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing
or moving parts.
1. Engage trigger lock.
2. Close the bleed-type master air valve.

3. Set pump to lowest possible fluid pressure, and start
pump.
4. Hold a metal part of the dispense valve firmly to a
grounded metal pail. Trigger the dispense valve
until clean solvent dispenses.
5. Remove valve from hose.

3. Disengage the trigger lock.

6. Follow Pressure Relief Procedure, and remove
fluid filter and soak in solvent. Replace filter cap.

4. Hold a metal part of the dispense valve firmly to a
grounded metal pail. Trigger the valve to relieve
pressure.

Daily Startup

5. Engage the trigger lock.
6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to dispense
again.
7. If you suspect the nozzle or hose is clogged or that
pressure has not been fully relieved after following
the steps above, VERY SLOWLY loosen the hose
end coupling to relieve pressure gradually, then
loosen completely. Clear hose or nozzle obstruction.

Flushing

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing
or moving parts.

1. Verify that the air needle valve is closed.
2. Connect the air line quick disconnect coupler to the
transfer pump
3. Turn on the main air supply.
4. Slowly open the air needle valve until the transfer
pump runs slowly.
5. Use the air needle valve to control the pump speed.
Caution
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed and could cause personal injury and/or damage to the pump. If the pump accelerates quickly or
starts running too fast, stop it immediately and check
the fluid supply. If the supply container is empty or air
has been pumped into the lines, refill the container
and prime the pump and the lines with fluid, or flush
and leave it filled with a compatible solvent. Be sure to
eliminate all air from the fluid system.
Do not attempt to operate pump unless it is securely
mounted in a drum.

•
•

Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
Flush with a fluid that is compatible with the
fluid being dispensed and the equipment wetted
parts.
