    • 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.
    • 公开了通过三甲氧基环硼氧烷和苄醇的加合物固化的环氧树脂的高耐热透明性,以抵抗这些透明胶片在军事和工业硬件上的强烈热量。 此外,透明度可以包括亚磷酸盐或磷酸盐化合物以改善耐热性,磷酸盐化合物具有足够的浓度以延迟凝胶时间,从而可以从组合物中除去苯基取代的烷基醇。 这种透明度可以存在于本领域技术人员已知的其它透明材料层的复合材料中。 使用中间体硫醇封端的树脂,环氧透明层以各种构型与其它透明层结合。 这些树脂极大地提高了整个透明度的边缘内和周围的透湿性。
