MicroFrost thixotropic inks are screen printable coatings currently used in manufacturing hydrophobic and super-hydrophobic diagnostic microscopy slides and microarray plates. The MH-series inks are heat-curable, super-hydrophobic and solvent resistant. The S-series is heat-curable, smooth, hydrophobic and oleophobic. U-series refers to UV-curable, smooth, hydrophobic and oleophobic inks. MicroFrost inks are available in many colors. MicroFrost inks can be optimized for flexographic printing, metered rods, spraying, pad printing, and other techniques.
