Coating on Peek

The basis for the development of a PS coating family (Spondycoat®) for PEEK-based components

Eurocoating's long-time experience in treating metallic implants with Air Plasma Spray and Vacuum Plasma Spray technologies was used as the basis for the development of a PS coating family (Spondycoat®) for PEEK-based components.

Features and benefits

Coatings available in titanium and hydroxyapatite

• highly adherent
• enhances osseointegration

Examples of application

Plain Peek:

• Spinal cages
• vertebral body replacements
• Carbon-fiber reinforced peek
• Spinal cages
• femoral stems
• acetabular caps
• fixation screw and plates
