CROSSLINKERS AND CHAIN EXTENDERS FOR ROOM TEMPERATURE VULCANIZATION OR CROSSLINKING OF POLYMERS

摘要

CROSSLINKERS AND CHAIN EXTENDERS FOR ROOM TEMPERATURE VULCANIZATION OR CROSSLINKING OF POLYMERS Silicon crosslinkers and chain extenders having at least two heterocyclic Si-N groups per molecule can be used to make compositions which cure in contact with moisture without generating a volatile leaving compound. These heterocyclic Si-N groups are illustrated by the following groups , , , , and These compositions are useful as coatings for substrates, encapsulants and sealants.
