MH-Series super-hydrophobic screen printing inks are translucent or pigmented. Thin films cure in 3 minutes at 200°C, have contact angles to water in excess of 140° and have great chemical and solvent resistance. These thixotropic inks are currently used in manufacturing hydrophobic and superhydrophobic immunological diagnostic microscope slides and microarray plates worldwide. Inks are available in a wide variety of colors including black, white, red, blue, yellow and a wide variety of other colors. Please contact Cytonix for custom color matching.

MH-series thixotropic inks are screen printable coatings used in manufacturing hydrophobic and super-hydrophobic diagnostic microscopy slides, microarray plates and microfluidic devices. The MH-series inks are heat-curable, super-hydrophobic and solvent resistant. Thin films cure by ramping heat from ambient to 200°C and maintain at 200°C for 20 minutes. The ink may be thinned with triethyl phosphate. Clean up with triethyl phosphate. Store unused ink at room temperature in tightly sealed container. After proper curing, masks have contact angles to water between 115 - 150° and have great chemical and solvent resistance. Inks are available in a wide variety of colors including black, white, red, blue, yellow and a wide variety of other colors.
