material notes

DuPont 7102 is a screen-printed solvent-based carbon conductive ink that provides lower resistance values than other similar carbon products. It can be used as a standalone product for circuitry, shielding or for overprinting of silver traces to prevent oxidation and silver migration. It can also be used in custom blends to achieve a wide range of resistance values when blended with DuPont 5025 silver, DuPont 7082 high resistance carbon and DuPont 5036 non-conductive binder. It can be printed using a variety of screen meshes including polyester and stainless steel. A 200SS mesh will achieve a dry film thickness of ~ 0.0005. It can be dried between 120°-140°C in 1-6 minutes in a conveyor oven or 15-30 minutes in a box oven. Lower temperatures require longer drying times to remove all of the solvents. Drying is also dependent on air flow and equipment design. Thinning can be accomplished using DuPont 3610. FOR REFERENCE ONLY
