With more extensive use of third firing decoration nowadays, and with the arrival of vetrosa, firing temperatures have been increasing to a range that fluctuates from 980° C to 1050° C with a cycle time of 50-60 minutes.
In accordance with this new trend, we have experimented with our new third firing colors and received positive results, including use with vetrosa. We suggest using screens from 77 up to 100 threads/cm2 .
These colors are completely intermixable. They can also be mixed with a white base TF 17019 to obtain pastel shades, or can be mixed with the flux TF 39028 to lighten colors. If you wish to improve the melting point of the colors, add the flux TF 39028 in varying proportions up to a ratio of 1:1.
For good results we propose our water-soluble medium TF 95 .The mixing ratio for screen printing paste is 50-60 parts of medium to 100 parts of color. The equipment and screens can be cleaned with water.
For the mixing process we suggest using a triple-roller mill or other refining machine. According to production needs, a longer drying time can be achieved by adding 5-10 % polyglycol.
