Isocyanate Conditions
Spraying materials containing isocyanates creates
potentially harmful mists, vapors, and atomized partic-
ulates.
Attach the (black) AAC air tubing to the AAC air

MSDS to know specific hazards and precautions
related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient ventila-
tion in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate per-
sonal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area. Attach the (Red) air hose to the chopper air

Material Self-ignition
Some materials may become self-igniting if applied
too thickly. Read material manufacturer's warnings
and material MSDS.

Moisture Sensitivity of
Isocyanites
Isocyanites (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 crystalli-

zation varies depending on the blend of ISO, the

humidity, and the temperature.
To prevent exposing ISO to moisture:
