The important factor in determining good adhesive strength is whether the surface energy of the substrate is close to or higher than the surface energy of the cured adhesive. Compared to epoxy hermetic seals, glass-to-metal seals can be operated up to much higher temperatures (250 °C for compression seals, 450°C for matched seals). Nature of Business. 0000007822 00000 n Under some low energy building, passive house, low-energy house, self-sufficient homes, zero energy building, and superinsulation standards, structures must be more air-tight than other lesser standards. When the glass and the metal being hermetically sealed have the same coefficient of thermal expansion, a "matched seal" derives its strength from bond between the glass and the metal's oxide. For more severe sour and corrosive applications, special precautions were required on the compressor package design, among which a patented hybrid … In addition to making a leak-tight connection, the grease lets two joints be later separated more easily.
