摘要

A high heat resistant transparency of epoxy resins cured with adducts of trimethoxyboroxine and benzyl alcohol is disclosed to resist intense heat for these transparencies in their use on military and industrial hardware. This transparency may exist in a composite with other layers of transparent material known to those skilled in the art. The epoxy transparency layer is bound to the other transparent layers, in a variety of configurations, using an interlayer of mercaptan terminated resins. These resins greatly improve resistance to moisture permeability in and about the edges of the entire transparency.
