Monodisperse silicones offer certain advantages over standard telechelic silicones. They have a discrete molecular weight and no low molecular weight non-functional cyclic siloxanes that can migrate out of the fluid or materials produced with them. Higher molecular weight vinyl-functional materials can be used as base silicones for 2-part RTVs.
