urethaneforming
Urethaneforming is the chemical process of forming urethane (carbamate) linkages through the reaction of an isocyanate with an alcohol group. In polyurethane technology, this reaction between polyisocyanates and polyols yields polymer networks known as polyurethanes. The core reaction is isocyanate plus alcohol to form a urethane linkage, typically accelerated by catalysts and influenced by temperature and moisture.
Typical formulations combine polyisocyanates (such as methylene diphenyl diisocyanate [MDI], toluene diisocyanate [TDI], or their polymeric
Processing approaches include one-component systems that cure upon exposure to moisture or heat and two-component systems
Safety and environmental considerations: isocyanates are potent sensitizers and can irritate the skin and respiratory system;
