Send me more info about this product...

A very large range of pigment dispersions is made by Kerley Ink Above, rubine red pigment  is being milled. We have what you are looking for in colorants for many different inks...

RadionBase MDEC Carbazole Violet is a special-purpose dispersion of Carbazole Violet (Violet 23) pigment in a 100% acrylic vehicle for energy cured (UV or EB) paste inks. RadionBase MDEC Carbazole Violet can be used as the sole colorant for making a mixing Violet ink for Quickset/Sheetfed Lithographic metal decorating or for printing on non-porous plastic substrates where flexibility and adhesion are very important as characteristics. Carbazole Violet has excellent chemical resistance and lightfastness qualities that make it ideal to make violet inks and even reflex blue inks (when combined with Phthalocyanine Blue) where exposure to harsh chemicals and strong light are anticipated.


Typically used to make mixing Violet inks, 45% to 65% of RadionBase MDEC Carbazole Violet by total formula weight is considered a normal loading for most paste ink formulas. Excellent results for metal decorating  and plastic film ink formulas can be obtained by blending RadionBase MDEC dispersions with Radion Vehicle MDEC letdown vehicle. Epoxy and Polyester acrylates should be tested for compatibility with any RadionBase MDEC dispersion before use, as they are marginally compatible. RadionBase MDEC series bases can be used for mercury UV, HUV, and LED UV formulas.
