Radio opaque screen printable ink

Radio opaque ink is ideal to print visible tags used with X-Ray, MRI or other imaging equipment. Conductive Compounds Inc., a Hudson, NH based manufacturer of specialty materials for the electronic assembly industry, have designed a new radio opaque ink RO-593 for use in applications requiring visible tags on devices and surfaces exposed to X-Ray, MRI and other fluorescing and imaging equipment.
The solvent based ink can be pad or screen printed, or dip coated onto a wide variety of substrates and dried quickly at low temperatures. It is a lower cost and safer material to use than metals such as lead and is possible to print small, intricate patterns if needed.
The new ink can be used for adhesive skin patches and other topical devices that are attached during X-Ray, CAT or MRI scan to highlight a target area. It is a white opaque paste that can be pigmented to create customized colors. Surgical devices, tools and other disposable items can be imprinted with the radio opaque ink to track them more easily.
For use on implantable devices, RO-593 would require overcoat of an additional protective ink or coating, and is compatible with Parylene and a wide variety of other overcoat materials.
When making prototypes or running short production cycles, the ink can be applied manually by brush or syringe. Cured films of RO-593 exhibit excellent adhesion to glass, metal, fabric, paper and most plastic substrates. It is compatible with all Conductive Compounds' silver conductive inks, carbon resistive inks, silver conductive epoxy adhesives, UV curable encapsulants and conformal coatings. It has excellent bend resistance once printed and dried.
