Freudenberg - Innovating Together


Mμ-Coat™ is a high-performance PTFE-enhanced coating solution for hypotube based catheter shafts. Mμ-Coat™ is applied using Freudenberg Medical’s state-of-the-art proprietary application technology – Cambus Coat™ - an environmentally friendly coating technique.

When Mμ-Coat™ is cured on the substrate metal, it forms a lubricious and non-stick matrix which is ideal for coating hypotube-based products.

Mμ-Coat™ is applied to catheter shaft solutions for cardiovascular and neurovascular device applications.
