Medthin™ 20 AlTiN
AITiN coating with great chemical barrier function
Medthin™ 20 AlTiN is widely used for the coating of medical instruments due to its anti-glare properties, superior adhesion high scratch resistance properties and its excellent chemical barrier function. The low light reflection properties help reducing surgeons’ eye fatigue during surgeries.
