    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. Additionally, the transparency may include phosphite or phosphate compounds to improve heat resistance, with the phosphate compound in sufficient concentrations to delay gel times such that the phenyl substituted alkyl alcohol may be eliminated from the composition. 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.

    摘要: Concentrated boric anhydride solutions containing more than 5% of boric anhydride in an organic solvent selected from mono or polyalcohols, trialkylborate and/or dialkylacetal when the solvent also contains an acid selected from sulfuric acid and/or aromatic acids. These solutions are used as hardeners of formo-phenolic resols, more particularly for the manufacture of laminates comprising glass fibers and formo-phenolic resols.
