Doctor Blades with Tungsten Carbid

All metal-qualities are also available with a ceramic or tungsten carbid coating on the top of the blade / bevel. A longer life-time and a lower friction coefficient of the blade are just two advantages of this improved technology.

Please take further technical facts from our datasheet at the end of the page.
