MacDermid Alpha Micromax 5075 Low-Cost Silver Carbon Conductor for EMC Shielding
Type: Silver Carbon Conductor
Application: EMC Shielding, Display Leads
Solids: 37–40%
Shelf Life: 3 months
Micromax 5075 is a silver carbon conductor ink for low-voltage flexible circuits where high conductivity is not required. It provides low cost per print, excellent screen life, and fast curing. Beyond conventional conductor use, it is particularly suitable for EMC shielding and display leads.
Micromax 5075 from MacDermid Alpha is a silver carbon conductor ink used to fabricate low-voltage circuitry, especially on flexible substrates. The composition targets low-cost conductive paths where very high conductivity is not required. Alongside conventional conductor applications, it is particularly suitable for EMC shielding and display leads. It runs on reel-to-reel, semi-automatic, and manual printers, and offers excellent screen life for longer print runs.
The ink carries 37–40% solids and viscosity 13–23 Pa.s. Box-oven drying is 120°C for 10 minutes; reel-to-reel drying is 140°C for 1 minute. Typical circuit line thickness is 7–10 μm. Cured film shows pencil hardness above 2H on 125μm polyester film. Work life exceeds 2 hours. Micromax 8210 is the listed thinner. Store sealed at 5–30°C; unopened shelf life is 3 months.

Frequently Asked Questions
When should I choose 5075 instead of a high-conductivity silver ink?
5075 is designed for low-cost conductive paths where high conductivity is not required. It makes sense for EMC shielding, display leads, and other low-voltage traces where cost control matters more than maximum conductivity.
Does 5075 support fast-curing production lines?
Yes. The TDS lists fast curing as a product benefit. Reel-to-reel drying runs at 140°C for 1 minute, which fits short cycle times on continuous lines.
What line thickness can be printed with 5075?
Typical circuit line thickness is 7–10 μm. Screen options include polyester 66T-130T and stainless steel 165-325 mesh.
How hard is the cured 5075 film?
Pencil hardness is greater than 2H by ASTM D3363-74, measured on 125μm polyester film. This reflects the abrasion resistance of the printed layer.
Why is 5075 shelf life shorter than other Micromax products?
The TDS lists 3 months in unopened containers from date of shipment for 5075, which is shorter than the 6 months listed for many other Micromax pastes. Plan purchasing and usage accordingly.
What thinner and clean-up solvent should be used with 5075?
Micromax 8210 is the listed thinner, used sparingly for small viscosity adjustments. Screen clean-up uses diethylene glycol ethyl ether acetate or ethylene glycol diacetate.
Which substrates work with 5075?
Polyester, polyimide, polycarbonate, and epoxy-glass are listed as compatible substrates. Typical physical properties in the TDS were measured on 125μm polyester film.
