Cross-contamination can result in cured
material in luid lines which could cause serious
injury or damage to equipment. To prevent
cross-contamination:
• Never
Never
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 NOTICE
NOTICE
Changing the material types used in your
equipment requires special attention to avoid
equipment damage and downtime.
• When changing materials, lush the equipment
multiple times to ensure it is thoroughly clean.
• Always clean the luid inlet strainers after
lushing.
• Check with your material manufacturer for
chemical compatibility.
• When changing between epoxies and urethanes
or polyureas, disassemble and clean all luid
components and change hoses. Epoxies often
have amines on the B (hardener) side. Polyureas
often have amines on the B (resin) side.

Exposure to moisture (such as humidity) will cause
ISO to partially cure, forming small, hard, abrasive
crystals that become suspended in the luid.
Eventually a ilm will form on the surface and the ISO
will begin to gel, increasing in viscosity.
NOTICE NOTICE 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 Never
Never store ISO in an open container.
• Keep the ISO pump wet cup or reservoir (if
installed) illed 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.
NOTE: NOTE:
NOTE: The amount of ilm formation and rate of
crystallization varies depending on the blend of ISO,
the humidity, and the temperature.

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.
