Micromax 5262L from MacDermid Alpha is a silver conductive ink developed for low temperature termination of tantalum capacitor cathodes. Typical target applications include consumer A/V and telecommunications components. The ink provides excellent electrical and mechanical stability, high temperature stability with low ESR, and high volumetric efficiency. Coverage around the component is consistent, with good thickness uniformity. The formulation is cadmium, lead, nickel, and phthalate free.
The ink carries 51–55% solids and viscosity 0.65–0.85 Pa.s. Micromax 8459 is the listed solvent or thinner. Tantalum is the substrate. Recommended paste prep is jar rolling for a minimum of 8 hours at 1–3 RPM to ensure homogeneity. Allow prints to air dry 15 minutes, then pre-dry at 80–120°C for a minimum of 10 minutes. Cure at >200°C for at least 20 minutes, or >220°C for at least 10 minutes. Post-cure in a static oven at 180–220°C (±10°C) for 2 hours. Store sealed at 5–30°C; unopened shelf life is 6 months.

Frequently Asked Questions
Why is 5262L used specifically on tantalum capacitors?
The TDS positions 5262L for low temperature termination of tantalum capacitor cathodes. It provides excellent electrical and mechanical stability, low ESR at high temperature, and consistent coverage around the component body.
How does jar rolling affect 5262L performance?
The TDS recommends jar rolling for a minimum of 8 hours at 1–3 RPM to ensure homogeneity prior to use. This step keeps the solids well distributed, which supports consistent coverage and thickness around the component.
What curing options does 5262L support?
Two cure windows are listed: >200°C for at least 20 minutes, or >220°C for at least 10 minutes. Both are followed by a post-cure in a static oven at 180–220°C (±10°C) for 2 hours.
Why is 5262L described as having high volumetric efficiency?
High volumetric efficiency means the ink delivers good conductivity with a relatively compact deposit, which supports smaller capacitor designs without sacrificing electrical performance.
Is 5262L free of cadmium, lead, nickel and phthalate?
Per the TDS, cadmium, lead, nickel, and phthalate are not intentional ingredients and are not intentionally added. Trace amounts may be present. Customers with strict compliance thresholds should verify against their own requirements.
What thinner should be used with 5262L?
Micromax 8459 is the listed solvent or thinner. Using the recommended thinner helps keep viscosity and application behavior consistent with the TDS values.
How should opened containers of 5262L be stored?
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.
