Important Two-Component Material Information
Isocyanate Conditions
Material Self-ignition
Keep Components A (Red) and
B(Blue)Separate
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.
NOTE: The amount of film formation and rate of crystal-
lization 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.
• Keep the pump wet cups filled with IsoGuard
Select™, part 24F516. The lubricant creates a bar-
rier 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.
Spraying or dispensing materials containing isocya-
nates 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 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.
Cross-contamination can result in cured material in
fluid lines which could cause serious injury or dam-
age equipment. To prevent cross-contamination of
the equipment’s wetted parts, never interchange
component A (Red) and component B (Blue) parts.

A (Red) and B (Blue) Components
313873C 9
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 (Red) side, but
some use ISO on the B (Blue) side. See the follow-
ing section.
A (Red) and B (Blue) Components
IMPORTANT!
Material suppliers can vary in how they refer to plural
component materials.
Be aware that when standing in front of the manifold on
proportioner:
• Component A (Red) is on the left side.
• Component B (Blue) is on the right side.
NOTE: On the VRM system, A (Red) is on the left side
of the base unit and B (Blue) is on the right side of the
base unit. The sides switch when going to the dispense
valve stand so that A (Red) is on the right side of the dis-
pense valve stand and B (Blue) is on the left side of the
dispense valve stand.
For all machines:
• The A (Red) side is intended for ISO, hardeners,
and catalysts.
• The B (Blue) side is intended for polyols, resins, and
bases.
NOTE: For machines with material volume ratios other
than 1:1, the higher volume side is typically the B (Blue)
side.
