MacDermid Alpha Micromax 5776B Lead-Free Gold Conductor for Ferrite Tape
Type: Gold Conductor Paste
Substrate: Ferrite Tape
Solids: 74–76%
Shelf Life: 6 months
Micromax 5776B is a gold conductor paste designed to be printed on ferrite tape. It is phthalate, cadmium, and lead free, with these substances not intentionally added. It uses Micromax 8250 as the recommended solvent or thinner, and carries 74–76% solids with a viscosity range of 170–230 Pa.s.
Micromax 5776B from MacDermid Alpha is an Au paste composition developed specifically to be printed on ferrite tape. It is positioned as a gold conductor layer for ferrite tape substrates, where the paste must handle the printing and subsequent firing requirements of ferrite-based circuit builds. The formulation is phthalate, cadmium, and lead free, with these substances not intentionally added, which supports applications with compliance requirements for these materials.
The paste carries 74–76% solids, with fineness of grind at ≤16 μm and ≤6 μm, and a viscosity range of 170–230 Pa.s. Micromax 8250 is the listed solvent or thinner. Store containers tightly sealed at 5–30°C; unopened shelf life is 6 months from date of shipment. Some settling of solids may occur during storage, so mix thoroughly before use.

Frequently Asked Questions
Why is 5776B described as a ferrite tape conductor?
The TDS states that Micromax 5776B is designed to be printed on ferrite tape. This makes it suitable as the gold conductor layer on ferrite tape substrates, where the paste must handle printing and subsequent firing on that specific base material.
What compliance declarations does 5776B carry?
Per the TDS, 5776B is phthalate, cadmium, and lead free, with these substances not intentional ingredients and not intentionally added. Trace amounts may be present. Customers with strict thresholds should verify against their own requirements.
What thinner should be used with 5776B?
Micromax 8250 is the listed solvent or thinner. Using the recommended thinner helps keep viscosity and print behavior consistent with the TDS values.
What are the fineness of grind and viscosity values?
Fineness of grind is ≤16 μm and ≤6 μm. Viscosity is 170 to 230 Pa.s. Solid content is 74 to 76 percent.
Does the 5776B TDS list drying or firing conditions?
The 5776B TDS does not list drying or firing conditions directly. For firing and processing details, contact the Micromax technical representative or refer to the corresponding ferrite tape technical data sheet.
How should 5776B be stored?
Store 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.
Can 5776B be used on substrates other than ferrite tape?
The TDS specifies ferrite tape as the intended substrate. For use on other substrates, contact the Micromax representative for recommendations, since compatibility may vary by substrate composition and processing conditions.
