Abstract: Polyepoxy silane compositions resulting from the reaction of olefinepoxide and poly(H)silanes crosslink in the presence of a catalytic amount of an 'onium catalyst when exposed to UV light. In one embodiment, two moles of an olefin-containing epoxy monomer are reacted with a bis(H)-containing silane of general formula R.sub.2 SiH.sub.2.
