Narrative:
We deiced with kilfrost abc-south plus at the gate. The deice crew deiced the nose of the aircraft and the windshield in addition to the rest of the aircraft. The deice fluid dried on the windshield during taxi out to 4L in ord making the visibility out of the windshield a bit difficult but not unsafe. During takeoff at approx 115 knots; the deice fluid separated from the nose of the aircraft and covered the windshield making it impossible to see out. All we could see was one center line light in front of us. The week before I was told by a 767 captain this exact same thing happened to him after deicing in london. This is a serious problem and in the future I will instruct the deice crews not to put any kilfrost fluid on the nose of the aircraft during deicing. Being in the middle of winter ops; a review of this problem is time sensitive.
