SUMMARY
Two-part pourable urethane foam consists of two main components: Part A, which typically contains a multifunctional isocyanate (such as di-isocyanate or tri-isocyanate), and Part B, which includes a multifunctional alcohol. Water is added to the alcohol component to initiate a decarboxylation reaction with the isocyanate, resulting in the formation of foam. This chemical reaction is crucial for the foam's expansion and structural properties.
