Abstract:
The invention describes a composition for sealing agent, generally in the form of glass frit, lead-free, comprising by weight over the total weight of the composition: 30-80% Bi2O3; 2- 10% ZnO; 2- 10% B2O3; 0-5% Na2O; 1- 10% SiO2; 1-8% A12O3; 0-7% BaO; and 0-8% MgO. The composition for sealing agent as defined above can be added with a filler in a quantity up to 20% by weight over the total weight of the resulting mixture. It also describes a sealing paste containing the composition for sealing agent, the possible filler, an organic binder and optionally an organic solvent. It also describes methods for producing the composition for sealing agent and the sealing paste.
