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
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.
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.
