Moisture Sensitivity of
Isocyanates
Exposure to moisture (such as humidity) will cause ISO to par-
tially cure, forming small, hard, abrasive crystal that become
suspended in the fluid. Eventually a film will form on the sur-
face 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 Sheet (SDS) to know specific hazards
and precautions related to isocyanates.
•
Use of isocyanates involves potentially hazardous proce-
dures. 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 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 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 sup-
plied-air respirator. Ventilate the work area according to
instructions in the fluid manufacturer’s SDS.
•
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.
Some materials may become self-igniting if applied too
thick. Read material manufacturer’s warnings and Safety
Data Sheet (SDS).
Cross-contamination can result in cured material in fluid
lines which could cause serious injury or damage equip-
ment. To prevent cross-contamination:
•
Never
interchange component A and component B
wetted parts.
•
Never use solvent on one side if it has been contami-
nated 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 mois-
ture. Always keep solvent containers closed when not in
use.
•
Always lubricate threaded parts with an appropriate
lubricant when reassembling.
