MacDermid Alpha Micromax 5029 High Print Thickness Silver for Smartcard Antenna
Type: Polymer Silver Ink
Application: Smartcard, RFID Antenna
Solids: 79.5–81.5%
Shelf Life: 6 months
Micromax 5029 is a polymer silver composition for printing coils or antennas in smartcards and RFID tags. It builds high print thickness in a single pass, carries 79.5–81.5% solids, and reaches 4–8 mΩ/sq after lamination at 25μm line thickness on PVC.
Micromax 5029 from MacDermid Alpha is a polymer silver composition developed for smartcard and RFID tag production. It is designed to print coils or antennas on flexible and rigid substrates, including polyester, PVC, polycarbonate, ABS, and polyimide. Normally only one print pass is required to reach the target thickness, which simplifies antenna processing and reduces intermediate handling.
The paste carries 79.5–81.5% solids and a viscosity range of 35–50 Pa.s. For 200 mesh stainless steel screens with 15μm emulsion, printed line thickness reaches 20–30μm; a 62T polyester screen with 20μm emulsion gives 18–22μm. After lamination, resistivity sits at 4–8 mΩ/sq at 25μm line thickness on 160μm PVC. Drying is 15–30 minutes at 50–60°C peak for PVC, or 2–5 minutes at 120–130°C peak for polyester. Store sealed at 5–30°C; unopened shelf life is 6 months.

Frequently Asked Questions
What makes 5029 suitable for smartcard and RFID antennas?
The TDS positions 5029 as a polymer silver composition for printing coils or antennas in smartcards and RFID tags. It builds high print thickness in a single pass, which suits antenna designs that need thicker tracks in fewer process steps.
How does lamination change the resistivity of 5029?
The TDS states that standard card lamination significantly reduces achieved resistance. After lamination, resistivity is 4–8 mΩ/sq at 25μm line thickness on 160μm PVC substrate.
Do I need more than one print pass with 5029?
Normally one print is enough to reach the target thickness. For very thick tracks, multiple prints can be used, with an intermediate drying stage in between.
Which screen builds work best for 5029?
Two TDS-documented builds: 200 mesh stainless steel with 15μm emulsion for 20–30μm lines, or 62T polyester with 20μm emulsion for 18–22μm lines. Stainless steel screens give higher definition and thicker prints at a given mesh count.
Why is a warm-up period important before printing 5029?
The TDS notes optimum printing characteristics are achieved at 20–23°C. Bring the container to this range before printing so the rheology and print thickness behave as expected.
Can 5029 be thinned with generic solvent?
Thinning is not normally required. Use the Micromax-recommended thinner for small viscosity adjustments or to replace evaporation loss. Too much thinner, or a non-recommended thinner, can change rheology and print characteristics.
How should 5029 be stored between production runs?
Keep containers tightly sealed at 5–30°C in a clean, stable environment. Unopened shelf life is 6 months from shipment. Some settling may occur, so mix thoroughly before reuse.
