Bonding and Adhesion
During catheter construction, many designs incorporate a supplemental layer added to the liner before braiding reinforcement is applied. This layer, frequently termed a tie layer, is a convenient method to enhance adhesion between layers. This is especially beneficial for catheter construction, where delamination of layered components can be a significant failure mode.
Tie Layer
Zeus Tie Layer is a thin polymer coating typically applied over liners during catheter construction. The Tie Layer is a fully melt-bondable surface that allows for full encapsulation of the braid during the jacket reflow process.
Key Benefits:
- Improves Bond Strength 20-40%1
- Coating Thickness as Low as 0.0001″ Ref. (0.0025 mm Ref.)
- Full Braid Encapsulation
Tie Layers are made from USP Class VI materials and may also be a good option for use with Zeus polyimide tubing. Strengthening catheter material adhesion can lead to fewer inspections, reduced production costs, and higher yields.
