WARNING
FIRE AND EX
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help
prevent fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and
plastic drop cloths (potential static arc).
• Keep work
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable
fumes are present.
• Ground all equipment in the work area. See Grounding instructions.
•Useonly
• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless
they are antistatic or conductive.
• Stop operation immediately if static sparking occurs or you feel a shock, Do not use
equipment until you identify and correct the problem.

Important Isocy
anate (ISO) Information
Important Iso
Isocyanates (ISO) are catalysts used in two
component materials.
cyanate (ISO) Information
Isocyanate Conditions
Spraying or dispensing materials containing
isocyanates creates potentially harmful mists,
vapors, and atomized particulates.
Read and understand 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.
Eventually a film will form on the surface and the ISO
will begin to gel, increasing in viscosity.
NOTICE

• 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 pump wet cup or reservoir (if
installed) filled with appropriate lubricant. The
lubricant creates a barrier between the ISO and
the atmosphere.
• Use only moisture-proof hoses compatible with
ISO.
• Never use reclaimed solvents, which may
contain moisture. Always keep solvent
containers closed when not in use.
• Always lubricate threaded parts with an
appropriate lubricant when reassembling.
NOTE: The amount of film formation and rate of
crystallization varies depending on the blend of ISO,
the humidity, and the temperature.
ured ISO will reduce performance and
ll wetted parts.
Keep Components A and B Separate
Cross-contamination can result in cured
material in fluid lines which could cause serious
injury or damage equipment. To prevent
cross-contamination:
• Never interchange component A and component
B wetted parts.
• Never use solvent on one side if it has been
contaminated from the other side.
Moisture Sensitivity of Isocyanates
Exposure to moisture (such as humidity) will cause
ISO to partially cure; forming small, hard, abrasive
crystals, which become suspended in the fluid.
