That makes me think of Dr. Mark Friedman in the L.A. area (he used to
teach at USC and lecture with Isaac Confortes) and what he said about
silane over ten years ago.

He doesn't use silane for porcelain bonding because of the short shelf
life. In his opinion, the silane was just as likely to be a lubricant
as an adhesive, depending on its chemical state at the time of use,
which the user can't readily measure.

Friedman recommended back in the early ninteties that you just skip the
silane. Instead, he was careful to micro-etch the interior of any
porcelain veneer or restoration, and that provided sufficient
retention. His experience was that a CLEAN, micro-etched porcelain
surface gave great retention.
