Solvent-Based Coating Systems
From Fluoropolymer Coatings - PTFE Medical Device
On the other hand, the solvent grade of PTFE coatings (PC 4006 Series and PC 403 Series) use a dry fully cured ground powder of PTFE. This fully cured ground micro powder of PTFE is then added to a solvent system containing a binder and pigments (no chromic acid or PFOA). Since the PTFE is already fully cured, only the final cure of the binder has to be reached in order to promote maximum adhesion to hold the PTFE particles in place. This is typically hundreds of degrees less than the dispersion grade helping to decrease oxidation of exposed metals.
