850G-9004 Acid Primer- Fluoropolymer Coating
Extreme Fluoropolymer Chemistry
Considered the “Gold Standard” coating for vascular wires, this acid primer PTFE coating represents over 40 years of research, development and refinement yielding a coating which has no recorded instances of performance defects. This coating is uniquely strong, yet flexible enough to allow the wire to bend and respond to procedural movement. Our coatings utilize a proprietary, acid primer system, infused with PTFE allowing for an extremely low coefficient of friction, high durability and surface adhesion in an efficient one-coat system. It can also be used as a primer or one-coat finish and utilization of this water-based system provide a non-flammable and low VOC formula vs. our solvent-based coating system that is also offered.
Coating Uses
- Hospital and Lab Equipment
- Dental Equipment
- Surgical Instruments

Coating Equipment & Application Recommendations
All of our PTFE coatings can be applied via spray, dip or spool-to-spool methods. Proper pre-coating wire cleaning treatment and post-application curing equipment is critical to guarantee performance and durability. Acceptable curing equipment includes high-temperature ovens which can safely maintain temperatures of 246 °C (475 °F) or utilize IR ovens. This will ensure proper sintering of the coatings onto the wire and promote the best surface characteristics that can be achieved.
