serious injury, and property damage.
WARNING

Important Isocyanate (ISO) Information
312666W 9
Important Isocyanate (ISO) Information
Isocyanates (ISO) are catalysts used in two component materials.
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 Sheet (SDS) 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 SDS.
• Use of incorrectly maintained or mis-adjusted equipment may result in improperly cured material.which
could cause off gassing and offensive odors. 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 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.
• Hazard from exposure to isocyanates continues after spraying. Anyone without appropriate personal
protective equipment must stay out of the work area during application and after application for the time
period specified by the fluid manufacturer. Generally this time period is at least 24 hours.
• Warn others who may enter work area of hazard from exposure to isocyanates. Follow the
recommendations of the fluid manufacturer and local regulatory authority. Posting a placard such as the
following outside the work area is recommended:

Important Isocyanate (ISO) Information
10 312666W
Material Self-ignition
Keep Components A and B
Separate
Moisture Sensitivity of
Isocyanates
Exposure to moisture (such as humidity) will
cause ISO to partially cure, forming small,
hard, abrasive crystal that become suspended
in the fluid. Eventually a film will form on the
surface 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.
Foam Resins with 245 fa
Blowing Agents
Some foam blowing agents will froth at
temperatures above 90°F (33°C) when not
under pressure, especially if agitated. To
reduce frothing, minimize preheating in a
circulation system.
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 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.
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
moisture. Always keep solvent containers closed
when not in use.
• Always lubricate threaded parts with an
appropriate lubricant when reassembling.

ClearShot Liquid

Changing Materials
ClearShot Liquid
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 manufacturer for
chemical compatibility.
• When changing between epoxies 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.
Read material MSDS to know specific
hazards and precautions related to
ClearShot Liquid.

Fluid in the hose and proportioner is still under
pressure. Follow the Pressure Relief Procedure
in the proportioner manual.
To relieve pressure in the hose manifold after the
gun is removed, place the fluid manifold over
containers, facing away from you. Ensure fluid
valves are closed. Very slowly open fluid
manifold check valves 2 to 2-1/2 turn. Under high
pressure, fluid will spray sideways from the fluid
ports.
