Testing of High-Temperature Ink for a Calcium Aluminum Silicate Refractory in the Aluminum Industry
A customer in the Czech Republic was in need of a specially formulated high temperature ink to be used to mark kiln fired products. They sent us pictures from ink they were currently using, which was hard to read and not holding up in the 700° C environment. They were marking a calcium aluminum silicate material with the company logo, the date, and the word “Fired”. They needed a specially formulated product that would be clear and legible after firing, as well as being opaque, with low viscosity characteristics. The 66W501 DuraFire™ marking ink met and exceeded all of these criteria.
This ink utilized our advanced mixing capabilities; once a base line formulation was determined, small samples were fired on test pieces at temperature. Each sample was microscopically inspected for cracking, sintering, adhesion, scoring, and glass development levels. This process was repeated until the optimal formula was achieved.
This comprehensive development and testing process produced one kilo of ink for this customer in less than 2 months. To learn more about this project, or the processes used to manufacture it, see the table below or contact us directly.
