* Much progress has been made in the last 8 years in understanding
the theory and practice of silane coupling agents. A major advance
in this direction was the measurement of true equilibrium constants
for the hydroly sis and formation of siloxane bonds. Equilibrium
constants for bond reten tion are so favorable that a silane
coupling agent on silica has a thousandfold advantage for bond
retention in the presence of water over an alkoxysilane bond formed
from hydroxy-functional polymers and silica. In practice, the bonds
of certain epoxies to silane-primed glass resist debonding by water
about a thousand times as long as the epoxy bond to unprimed glass.
Oxane bonds of silane coupling agents to metal oxides seem to
follow the same mechanism of equilibrium hydrolysis and rebonding,
although equilibrium constants have not been measured for
individual metal-oxygen silicon bonds. This suggests, however, that
methods of improving bond retention to glass will also improve the
water resistance of bonds to metals. of standard coupling agents
with a hydrophobic silane or one Modification with extra siloxane
cross-linking have improved the water resistance of bonds to glass
and metals another hundredfold over that obtained with single
coupling agents."
