Overview
Usage
XM plural-component sprayers can mix and spray most
two-component epoxy and urethane protective coatings.
When using quick-setting materials (less than 10 minute
pot life) a remote mix manifold must be used.
XM plural-component sprayers are operated via user
interface, air controls, and fluid controls.
Isocyanate Hazard
Material Self-Ignition
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
urethane 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.
NOTE:
The amount of film formation and rate of crystallization
varies depending on the blend of ISO, the humidity, and
the temperature.
To prevent exposing ISO to moisture:
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere. Never
store ISO in an open container.
• Use moisture-proof hoses specifically designed for
ISO, such as those supplied with your system.
• Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
• Never use solvent on one side if it has been contam-
inated from the other side.
• Always park pumps when you shutdown.
• Always lubricate threaded parts with Part 217374
ISO pump oil or grease when reassembling.
XM OEM sprayers are not approved for use in hazard-
ous locations.
Spraying materials containing isocyanates creates
potentially harmful mists, vapors, and atomized partic-
ulates.
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 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.
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
material MSDS.
