Title: GLASS PASTE
Abstract:
A glass paste which comprises a glass powder material and an organic vehicle, characterized in that: the organic vehicle contains 0.1 to 5 mass% of an organic binder relative to the mass of the glass paste; the organic binder is a polymer having hydroxyl groups; a hydroxyl-bearing monomer accounts for at least 15mol% of the monomers constituting the polymer; and the viscosity of the glass paste at 25°C is 100 to 100000 mPa·s. This glass paste is advantageous in that: no pinhole defects occur during the application or firing of the paste; and the firing of the paste can be completed in a short time.
