Crosslinkers and chain extenders for room temperature vulcanization or crosslinking of polymers.

摘要

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 <CHEM> and <CHEM> These compositions are useful as coatings for substrates, encapsulants and sealants.
