    • Glass Frits are composed of fine glass particles that are melted and cooled to form solid, spherical shapes. They are primarily used as a binder or adhesive for electronic components, such as capacitors, resistors, and transistors.

    • Okuno's Glass Frits come in a variety of colors, particle sizes, and chemical compositions to meet the specific needs of their customers. They are designed to provide high adhesion, low firing temperature, and excellent electrical insulation properties.

    Glass frit can't be printed on substrates directly because it is powder. Thus, organic vehicles (resin and solvents) are mixed with glass frit to make glass pastes, and the glass pastes are applied on substrates by screen printing. After the printing, the substrates are fired slowly to melt glass and to decompose the organic vehicles by heat. After firing, only glass remains on substrates since glass is an inorganic material. The organic vehicles are decomposed by heat and released into the air as carbon dioxide.
