WARNING

Important Isocyanate (ISO) Information
6 309577ZAA
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
309577ZAA 7
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.
Changing Materials
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.
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.

Fill the Wet-Cups
1. Component A (ISO) Pump: Keep reservoir (R) 3/4
filled with Graco Throat Seal Liquid (TSL), Part No.
206995. Wet-cup piston (28) circulates TSL through
packing nut/wet-cup (19), to carry away isocyanate
film on displacement rod.
After some time TSL will thicken and darken, and
must be replaced. Thick, dirty TSL will not pump
through lines and will harden in wet-cup. Check
condition of TSL every week, minimum, and change
when needed.
2. Component B (Resin) Pump: Check felt washers
(21) in packing nut/wet-cup (19) daily. Keep
saturated with Graco Throat Seal Liquid (TSL), Part
No. 206995, to prevent material from hardening on
displacement rod. Replace felt washers when worn
or contaminated with hardened material.
