MICROMAX
Micromax™ 7102
Item number: DP710200-100G
A solvent-based, screen printable carbon that possesses good conductivity for printing polymer thick film traces
material notes
Micromax™ 7102 (formerly known as 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 Micromax™ 5025 silver, Micromax™ 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 Micromax™ 3610. FOR REFERENCE ONLYKey Properties
