MediShield™ Hydrophobic Lubricious (MSLIP) Coating
MediShield™ MSLIP Coating is engineered to provide exceptional dry lubricity for medical devices
that must slide smoothly against another surface - for example, a tube moving within an over-tube.
Its performance is comparable to PTFE coatings, while offering the added benefit of being completely
PFAS-free.
Benefits
- Biocompatible: Tested according to ISO 10993 standards
- Exceptional Dry Lubricity: Coefficient of friction comparable to PTFE
- Strong Adhesion: Durable bonding to many substrates
- Excellent Durability: Maintains lubricity performance through repeated testing
- PFAS-Free: Contains no per- and polyfluoroalkyl substances
Application Examples
- Endoscopy over-tube systems
- Catheter delivery systems
- Guidewire sheaths
- Insertion tubes for diagnostic instruments
