Fort Wayne Metals offers advanced PTFE synthetic fluoropolymer coatings for a wide range of medical applications in order to increase lubricity and chemical resistance. Our proprietary spool-to-spool process provides an exceptionally smooth, uniform coating with a lower coefficient of friction than spray techniques. Our PTFE coatings can be applied to any of our stainless steel, high performance alloys, and Nitinol without compromising their elastic properties.
By utilizing our proprietary coating processes, we are able to provide our customers with a uniform coating for medical device components. With the excellent control we possess over the coating thickness, we are able to guarantee tight tolerances as well. Typical products include dead-straight stylets for PTCA guidewires, guidewire cores and catheter stylets using our SLT® wire.
As the preferred coating used for coiling wire applications and mandrel, this process is unique in the fact that we coat the wire before it is coiled. LubriSkin™ results in a consistently smooth, non-cracking or flaking coating that exceeds the expectations for typical precoated, coiled wire. Available in a variety of colors, LubriSkin™ can only be applied to round wires.
