‘The ultimate resolution is correlated to the ability of the prepolymer to conform to the surface and the ability of the cross-linked polymer to retain the molded shape,’ Rogers said.
the prepolymer forms a polymerized gel when activated
Artificial clays containing a catalyst can initiate polymerization when the particles are mixed with a prepolymer matrix.
Some researchers believe that prepolymers achieve better results.
Siloxanes are prepolymers - the result of partial polymerization of silanes - in which the molecules are beginning to link, but only in sets of two or three, not yet in full chains.
