WARNING

Important Isocyanate (ISO) Information
6 3A8563B
Important Isocyanate (ISO) Information
Isocyanate Conditions Keep Components A and B
Separate
Moisture Sensitivity of
Isocyanates
Exposure to moisture (such as humidity) will cause ISO
to partially cure, forming small, hard, abrasive crystal
that become suspended in the fluid. Eventually a film
will form on the surface and the ISO will begin to gel,
increasing in viscosity.
NOTE: The amount of film formation and rate of
crystallization varies depending on the blend of ISO, the
humidity, and the temperature.
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 Sheets (SDSs) to know
specific hazards and precautions related to
isocyanates.
• Use of isocyanates involves potentially hazardous
procedures. Do not spray with this equipment
unless you are trained, qualified, and have read and
understood the information in this manual and in
the fluid manufacturer’s application instructions
and SDSs.
• 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 isocyanate 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 SDSs.
• Avoid all skin contact with isocyanates. 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 interchange component A and component
B wetted parts.
• Never use solvent on one side if it has been
contaminated from the other side.
NOTICE
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
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.

Changing Materials
NOTICE
Changing the material types used in your equipment
requires special attention to avoid equipment damage
and downtime.
• 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.
• When changing between epoxies and urethanes or
polyureas, disassemble and clean all fluid
components and change hoses. Epoxies often
have amines on the B (hardener) side. Polyureas
often have amines on the B (resin) side.
