Medthin™ 20 AlTiN

Excellent antireflection coating for instruments

Medthin™ 20 AlTiN is widely used for the coating of medical instruments due to its anti-glare properties, superior adhesion, low wear and high scratch resistance properties and its excellent chemical barrier function.

The low light reflection properties help reducing surgeons’ eye fatigue during operations.

This coating shows excellent life time records under the toughest surgical conditions expected from medical instruments.

Field experience proves that Medthin™ 20 AlTiN withstands over thousands of cleaning and sterilization cycles without any signs of damage. Medthin™ 20 AlTiN can be sterilized by means of any technique.

Medthin™ 20 AlTiN is deposited at temperatures between 150 and 450 °C. This wide range of temperatures allows for a variety of instrument materials to be coated below the respective tempering and annealing temperature which ensures that no softening or geometrical changes will occur.
