Raw materials and additives of polyurethane systems
Polyurethanes are typically formed by the reaction of polyols with isocyanates. Isocyanates also react with amines in the formulation, forming urea linkages. These materials create an unstable intermediate, carbamic acid, which decomposes into amines and carbon dioxide when reacting with water. Additionally, the crosslinking (curing) process depends on the type of isocyanate structure used.
