Mechanism of Action
The mechanism of action of Pt303 in polyurethane systems is primarily based on its ability to catalyze the reaction between isocyanates and hydroxyl groups. The tertiary amine functional group in Pt303 donates a pair of electrons to the isocyanate group, forming a complex that lowers the activation energy of the reaction. This results in faster formation of urethane linkages, which are responsible for the cross-linking and solidification of the foam.
In addition to accelerating the urethane reaction, Pt303 also influences the gel and blow reactions. The gel reaction refers to the formation of a rigid network within the foam, while the blow reaction involves the generation of carbon dioxide gas, which creates the cellular structure. By carefully balancing these reactions, Pt303 ensures that the foam has the right density, hardness, and resilience for automotive applications.
