System140 colors are zinc-based and heavy metal-free; they do not contain intentional additions of lead (Pb), cadmium (Cd), mercury (hg) and hexavalent chromium, (Cr+6).
System140 colors show performance similar to lead-containing colors for flat glass based on rigorous testing to evaluate alkali resistance, sulfide and acids that include hydrochloric, sulfuric, acetic and citric acid.
The System140 intermixable color range is formulated with strict controls to minimize color drift, resulting in superior lot-to-lot consistency. Thorough testing methods also ensure the firing stability of mixed shades for customers that prefer to make their own in-house color matchings.
System140 colors have been designed to comply with GANA specifications for spandrel glass used in building windows and other architectural applications.
System140 flat glass enamels are formulated for typical glass tempering cycles with furnace temperatures set at 1180 – 1300 °F (635 – 705 °C) with a total cycle time of 40 seconds per millimeter of glass thickness.
This results in typical glass temperatures of 1145 – 1220 °F (620-660 °C).
