Important Isocyanate (ISO) Information
Isocyanate Conditions
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.

Important Isocyanate (ISO) Information
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.
Material Self Ignition
Some materials may become self-igniting if applied
too thickly.. Read material manufacture's warnings
and material MSDS.
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
foam and polyurea coatings. ISO will react with
moisture (such as humidity) to form 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. If used, this
partially cured ISO will reduce performance and the life
of all wetted parts.
The amount of film formation and rate of crystallization
varies depending on the blend of ISO, the humidity, and
the temperature.
