Two-part silicone's are created through the mixing of 2 components. Component 1 is a rubber base compound that is mixed with component 2 that is a curing agent. A more in depth look at each component shows that Component 1 is made up of a polymer and sometimes additional fillers and additives, while component 2 contains chemical crosslinkers and catalyst. When component 1 and 2 are mixed, the mixture immediately starts curing to form the silicone into its final form.
