Boyd Coatings Research officials have announced the capability to coat Nitinol medical devices with un-modified PTFE (or other high-temperature-cured fluoropolymer coatings) without adversely affecting the properties of the underlying Nitinol material. Typically, pure PTFE requires temperatures of 700°F to cure. Because Nitinol materials cannot tolerate temperatures beyond 500°F without suffering adverse reactions, PTFE was previously applied using hybrid forms where a resin binder was added and it was the binder that cured at lower temperatures.
