Chemical Description

Silicone resins are normally supplied for use as solutions, prepared as described above. The final conversion of the partially polymerized soluble material into a fully cross-linked product is carried out in situ. In the crosslinking process, remaining silanol groups are condensed by heating in the presence of a catalyst, e.g. zinc octo ate, cobalt naphthenate or triethanolamine.
