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 performance and the life of all wetted parts.   Spraying or dispensing materials containing isocya-   nates 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.   NOTE: The amount of film formation and rate of crystal-   lization varies depending on the blend of ISO, the   humidity, and the temperature.   Prevent inhalation of isocyanate mists, vapors, and   atomized particulates by providing sufficient ventila-   tion in the work area. If sufficient ventilation is not   available, a supplied-air respirator is required for   everyone in the work area.   To prevent exposing ISO to moisture:   • Always use a sealed container with a desiccant   dryer in the vent, or a nitrogen atmosphere. Never   store ISO in an open container.   To prevent contact with isocyanates, appropriate per-   sonal protective equipment, including chemically   impermeable gloves, boots, aprons, and goggles, is   also required for everyone in the work area.   • Keep the ISO lube pump reservoir (if installed) filled   ™ ™ with Graco Throat Seal Liquid (TSL ), Part   206995. The lubricant creates a barrier between the   ISO and the atmosphere.   Material Self-ignition   • • Use moisture-proof hoses specifically designed for   ISO, such as those supplied with your system.   Never use reclaimed solvents, which may contain   moisture. Always keep solvent containers closed   when not in use.   Some materials may become self-igniting if applied   too thickly. Read material manufacturer’s warnings   and material MSDS.   • • Never use solvent on one side if it has been contam-   inated from the other side.   Always lubricate threaded parts with ISO pump oil   or grease when reassembling.   Keep Components A and B   Separate   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.   Cross-contamination can result in cured material in   fluid lines which could cause serious injury or dam-   age equipment. To prevent cross-contamination of   the equipment’s wetted parts, never interchange   component A (isocyanate) and component B (resin)   parts.   313872N   11   Download from Www.Somanuals.com. All Manuals Search And Download.   Important Two-Component Material Information   Changing Materials   • When changing materials, flush the equipment mul-   tiple times to ensure it is thoroughly clean.   • • Always clean the fluid inlet strainers after flushing.   Check with your material manufacturer for chemical   compatibility.   • • Most materials use ISO on the A side, but some use   ISO on the B side.   Epoxies often have amines on the B (hardener)   side. Polyureas often have amines on the B (resin)   side.   A (Red) and B (Blue)   Components   IMPORTANT!   Material suppliers can vary in how they refer to plural   component materials.   Be aware that when standing in front of the manifold on   proportioner:   • • Component A (Red) is on the left side. The A (Red)   side is intended for ISO, hardeners, and catalysts.   Component B (Blue) is on the right side.The B   (Blue) side is intended for polyols, resins, and   bases.   For ratios higher than 1:1, the higher volume is typically   the B (Blue) side.   • Most polyurethanes use ISO on the A (Red) side   and polyol on the B (blue side, but some use ISO on   the B (Blue) side.   • • • Epoxies often have amines on the B (hardener) side   Polyureas often have amines on the B (resin) side.   Silicones often have the catalyst on the B side.   12   313872N   Download from Www.Somanuals.com.
