Important Isocyanate Information
Isocyanates (ISO) are catalysts used in two component materials.
Important Isocyanate Information
Isocyanate Conditions
Spraying or dispensing materials containing
isocyanates 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
ventilation in the work area. If sufficient ventilation
is n ot available, a suppl ied-air respirator is required
for everyone in the work area.
To prevent contact with isocyanates, appropriate
personal protective equipment, including
chemically imperm eab le gl ov es , bo ots, ap rons ,
and goggles, is also required for everyone in the
work area.
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 s ide 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.
Eventually a film will form on the surface and the ISO
will begin to gel, increasing in viscosity
Material Self-Ignition
Some materials may become self-igniting if appli ed
too thick. Read material manufacturer’s warnings
and material MSDS.
NOTICE
Partially cured ISO will reduce performance and
the life of all wetted parts.
• Always use a sealed container with a de siccant
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.

Important Isocyanate Information
Foam Resins with 245 fa Blowing
Agents
Some foam blowing a gen ts will froth at temp eratu res
above 90°F (33°C) when not under pressure,
especially if agitated. To reduce frothing, minimize
preheating in a circulation system.
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 m anufacturer for
chemical compatibility.
• When changing between ep oxies 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.
