1. An organic compound containing the isocyanate group (-N=C=O), used especially in the manufacture of polyurethane plastics and coatings.
Usage: technical; chemistry

Examples

• Isocyanates are key raw materials in polyurethane foam production.
• The factory uses isocyanate compounds to manufacture rigid insulation panels.
• Workers handling isocyanates must wear protective equipment due to potential respiratory hazards.
• Methyl isocyanate is a highly toxic chemical used in pesticide synthesis.
• Isocyanate-based coatings provide excellent durability and chemical resistance.
• The reaction between isocyanates and polyols creates the polyurethane polymer.
