MacDermid Alpha Micromax 3992 is a silver conductor paste designed for electrically heated glass applications. Offering 3.2-6.5 mΩ/sq resistivity with 64.8-66.3% solid content — part of the 399X Series with blendable members for resistance tuning. Pb/Cd/Ni/phthalate free per TDS specifications.
Part of the Micromax 399X Series, Micromax 3992 is a silver conductor composition specifically designed for heated glass defogger applications. This paste provides excellent printability and high print definition, delivering a robust fired layer that is resistant to environmental and chemical influences. The series members can be blended with each other to obtain a wide range of electrical resistance values, offering design flexibility for various heated window designs.
With a solid content of 64.8-66.3% and viscosity of 35-50 Pa.s per TDS specifications, Micromax 3992 is optimized for screen printing using 150-280 mesh screens with 12-25 μm emulsion thickness. Drying is performed at 125-150°C. The paste fires at 600-670°C over enamel and 600-700°C over glass with a 30-minute firing cycle. The composition is supplied ready to print with enhanced green strength and a wide process window when co-firing over enamels. Available in standard packaging.
