Isocyanates (ISO) are catalysts used in two
component materials.

Spraying or dispensing fluids that contain
isocyanates creates potentially harmful mists,
vapors, and atomized particulates
• Read and understand the fluid manufacturer’s
warnings and Safety Data Sheet (SDS) to know
specific hazards and precautions related to
isocyanates.
• Use of isocyanates involves potentially
hazardous procedures. Do not spray with the
equipment unless you are trained, qualified,
and have read and understood the information
in this manuals and in the fluid manufacturer’s
application instructions and SDS.
• Use of incorrectly maintained or mis-adjusted
equipment may result in improperly cured
material. Equipment must be carefully
maintained and adjusted according to
instructions in the manual.
• To prevent inhalation of isocynate mists, vapors,
and atomized particulates, everyone in the
work area must wear appropriate respiratory
protection. Always wear a properly fitting
respirator, which may include a supplied-air
respirator. Ventilate the work area according to
instructions in the fluid manufacturer’s SDS.
• Avoid all skin contact with iscocyanates.
Everyone in the work area must wear chemically
impermeable gloves, protective clothing and
foot coverings as recommended by the fluid
manufacturer and local regulatory authority.
Follow all fluid manufacturer recommendations,
including those regarding handling of
contaminated clothing. After spraying, wash
hands and face before eating or drinking.

Cross-contamination can result in cured
material in fluid lines which could cause serious
injury or damage equipment. To prevent
cross-contamination:
• Never

Never interchange component A and component
B wetted parts.
• Never use solvent on one side if it has been
contaminated from the other side.

Exposure to moisture (such as humidity) will cause
ISO to partially cure; forming 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.

Partially cured ISO will reduce performance and
the life of all wetted parts.
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere.
Never
Never
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:
NOTE:
NOTE: The amount of film formation and rate of
crystallization varies depending on the blend of ISO,
the humidity, and the temperature.
