Micromax 4922N Air-Dry Silver Conductor, Tantalum Capacitor
Type: Air-Dry Silver Conductor
Application: Tantalum Capacitor / PCB Repair
Cure: RT or 60-100°C
Shelf Life: 6 months
MacDermid Alpha Micromax 4922N is a high metal content, high viscosity air-dry silver conductor designed for tantalum capacitor anode metallization and circuit board repair. Featuring higher conductivity than 4817N, suitable for brush, stylus, or machine banding applications per TDS specifications.
Micromax 4922N is a high metal content, high viscosity air-dry silver conductor composition designed for general purpose conductive applications requiring higher conductivity. This product is the high-solids version of Micromax 4817N, offering superior electrical performance for brush, stylus, or machine banding applications. The composition is widely used in tantalum capacitor anode metallization, circuit board repair, and electroplating base applications. It exhibits a moderately fast drying rate with good adhesion to most substrates.
The paste cures in 16-20 hours at room temperature (25°C) or in 1 hour at 60-100°C, providing flexibility for various production processes. For brush, stylus or machine banding applications, Micromax 4922N delivers higher conductivity compared to 4817N. The composition can be thinned with butyl acetate or Micromax 8459 to achieve optimum application properties. Available in standard packaging with 6-month shelf life per TDS specifications.
