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 pro- viding sufficient ventilation in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for every- one in the work area.

To prevent contact with isocyanates, appro- priate personal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Material Self-ignition

Some materials may become self-igniting if applied too thickly. Read material manufac- turer’s warnings and material MSDS.

Keep Components A and B Separate

Cross-contamination can result in cured material in fluid lines which could cause seri- ous injury or damage equipment. To prevent cross-contamination of the equipment’s wet- ted parts, never interchange component A (isocyanate) and component B (resin) parts.

Moisture Sensitivity of Isocyanates

Isocyanates (ISO) are catalysts used in two component foam and polyurea coatings. ISO will react with moisture (such as humidity) to form 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. If used, this partially cured ISO will reduce perfor- mance and the life of all wetted parts.

The amount of film formation and rate of crystallization varies depending on the blend of ISO, the humidity, and the tem- perature.

To prevent exposing ISO to moisture:

Always use a sealed container with a des- iccant dryer in the vent, or a nitrogen atmo- sphere. Never store ISO in an open container.

Keep the ISO lube pump reservoir (if installed) filled with Graco Throat Seal Liq- uid (TSL), Part 206995. The lubricant cre- ates a barrier between the ISO and the atmosphere.
