Page 5: Important Isocyanate (Iso) Information
Important Isocyanate (ISO) Information Important Isocyanate (ISO) Information Isocyanates (ISO) are catalysts used in two component materials. Isocyanate Conditions Spraying or dispensing fluids that contain isocyanates creates potentially harmful mists, vapors, and atomized particulates. • Read and understand the fluid manufacturer’s warnings and Safety Data Sheets (SDSs) to know specific hazards and precautions related to isocyanates. -
Page 6: Material Self-Ignition
Important Isocyanate (ISO) Information Material Self-Ignition Moisture Sensitivity of Isocyanates Exposure to moisture (such as humidity) will cause ISO to partially cure, forming small, hard, abrasive crystals that become suspended in the fluid. Eventually a film will form on the surface and the ISO will begin to gel, Some materials may become self-igniting if applied too thick. -
