758 SERIES LEAD-FREE FLAT GLASS COLORS
Ferro’s 758 Series lead-free colors for flat glass are designed for a large variety of applications such as appliance glass, architectural glass including spandrel panels, shower screens, internal glass doors and partitions, as well as glass furniture that includes tabletops, kitchen cabinets, cupboard doors and display cabinets.
Colors in the 758 Series glass enamels provide general moderate chemical resistance with the following properties:
| ACID RESISTANCE | ALKALI RESISTANCE |
| ASTM C 724 (10% citric acid and 3.7% HCl ,20±2℃, 15 min.) | ASTM C 1203 (10% NaOH ,95±3℃, 2h) |
| Level 4 or better for hydrochloric acid and Level 3 or better for citric acid | Weight loss less than 0.0028 g/cm2 (except the metallic colors) |
758 Series flat glass enamels provides an intermixable color palette that can be blended with other intermediates within the color series, resulting in the widest possible color range. This allows decorators to mix and match their own shades for optimal productivity with minimal inventory.
Colors in this system do not contain voluntary additions of heavy metals–lead (Pb), cadmium (Cd), mercury (Hg) and hexavalent chromium (Cr6+). Exceptions are the cadmium green, yellow and red (marked *) which need to use cadmium pigments to provide the color tones required by the market.
For lead-free and cadmium free colors, the amount of lead, hexavalent chromium (Cr6+) , and mercury is less than 1000 ppm; the cadmium amount is less than 100 ppm .
Our flat glass enamels are developed and controlled for the following application processes:
- Direct screen Printing
- Roller coating
