The addition of initiator affects the crossover point of the storage modulus (solid line) and the loss modulus (dashed lined), which indicates curing. As initiator content increases, the reaction proceeds more quickly.
Controlling curing kinetics and network structure of polysiloxanes

The approach is to use peroxides to modify the reaction kinetics in the production of polysiloxanes.  A radical initiator in the presence of a hydride-terminated polysiloxane will increase the rate of curing and reduce manufacturing costs.  At a minimum a formulation would contain a hydride-terminated polysiloxane, a platinum catalyst, and an initiator that generates radicals.  The content of…
