Important Isocy

anate (ISO) Information

Important Iso

Isocyanates (ISO) are catalysts used in two component materials.

cyanate (ISO) Information

Isocyanate Conditions

Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates.

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 ventilation 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 personal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Keep Components A and B Separate

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.

Moisture Sensitivity of Isocyanates

Exposure to moisture (such as humidity) will cause ISO to partially cure; forming 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.

NOTICE

Partially cured ISO will reduce performance and the life of all wetted parts.

• Always use a sealed container with a desiccant

Material Self-ignition

Some materials may become self-igniting if applied too thick. Read material manufacturer’s warnings and material MSDS.

3A2800B 9

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.

NOTE: The amount of ﬁlm formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the temperature.
