Abstract: An enamel paste composition includes glass frit; a pigment; and an organic carrier medium; wherein the glass frit includes at least two glass frits including a first glass frit and a second glass frit, and wherein the first glass frit has a larger particle size and a higher glass transition temperature than the second glass frit. Also described is a method of forming an enamel coating by depositing the enamel paste composition on a substrate; and firing the enamel paste to form an enamel coating on the substrate, the enamel coating having a heterogeneous frit microstructure with particles of the first frit embedded in a matrix of second frit.

Abstract: The present invention relates to a particle mixture comprising particles of glass frit and particles of a crystalline oxide material, wherein the glass frit comprises silicon oxide (SiO2), zinc oxide (ZnO) and sulfur (S) and wherein the D90 particle size of the particle mixture is less than 5 microns. The particle mixture may be used to apply an enamel to a substrate. The present invention further relates to the use of the particle mixture to form an enamel on a substrate, to a glass sheet and to an automotive window pane.
