    • Casting resin compositions for sealing opto-electronic components on the basis of quick-setting casting resin compounds, consisting of at least one epoxy compound with a cycloaliphatic base with at least two oxiran rings in the molecule, at least one carbonic acid anhydride, a zinc octoate, a low-molecular polyol and/or a low-molecular acid ester and, optionally, an organic phosphorus compound and customary brighteners and light-scattering material in powder form and pigments. Especially suitable is a zinc octoate with a zinc content of 21 to 22% by weight. The compounds are used for covering and coating light-emitting diodes, photo transistors, photo diodes and light-emitting diode displays and as light guides for opto-electronic couplers.
    • 基于快速凝固浇铸树脂化合物的密封光电子部件的铸造树脂组合物,由至少一种环氧化合物与分子中具有至少两个环氧乙烷环的脂环族基团组成,至少一种碳酸酐,锌 辛酸酯,低分子多元醇和/或低分子酸酯,以及任选的有机磷化合物和粉末形式和颜料的常规增白剂和光散射材料。 特别合适的是锌含量为21〜22重量%的辛酸锌。 这些化合物用于覆盖和涂覆发光二极管,光电晶体管,光电二极管和发光二极管显示器以及光电耦合器的光导。

    • The invention relates to a method for the manufacture of transparent casting resins. According to the invention, a liquid acid anhydride (b) is admixed to a premixture (a), which is liquid at room temperture, of zinc octoate, a low-molecular weight acid ester and, optionally, an organic phosphite, and this mixture of (a) and (b) is added, preferably at temperatures .ltoreq.50.degree. C., to liquid aromatic diglycidyl ethers. Diphenyldecyl phosphite is particularly well suited as an organic phosphite. The casting resins obtained are transparent and find use particularly for casting-in and encapsulating opto-electronic components such as light-emitting diodes (and diode displays), photo diodes and photo transistors.
    • 本发明涉及制造透明浇铸树脂的方法。 根据本发明,将液体酸酐(b)与室温下为液体的预混合物(a),辛酸锌,低分子量酸酯和任选的有机亚磷酸酯混合,并将该混合物 (a)和(b)的混合物优选在温度<50℃下加入到液体芳族二缩水甘油醚中。 亚磷酸二苯基癸酯特别适合作为有机亚磷酸酯。 获得的铸塑树脂是透明的,特别适用于铸造和封装诸如发光二极管(和二极管显示器),光电二极管和光电晶体管的光电组件。
