Siloxane. Polydimethylsiloxane is a prevalent siloxane. In organosilicon chemistry, a siloxane is an organic compound containing a functional group of two silicon atoms bound to an oxygen atom: Si−O−Si. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H [OSiH2]nOH and [OSiH2]n. [1]
Silicone resin. Silicone resins are a type of silicone material which is formed by branched, cage-like oligosiloxanes with the general formula of RnSiXmOy, where R is a non-reactive substituent, usually methyl (Me = −CH3) or phenyl (Ph = −C6H5 ), and X is a functional group: hydrogen ( −H ), hydroxyl ( −OH ), chlorine ( −Cl) or alkoxy ...
