Real Time Folding Kinetik

The RT-FK equipment is an excellent tool for paint and varnish development and for the dimensioning of excimer VUV matting sytem. The complete measuring station can be purchased at IOT GmbH.

In a chamber inerted with pure nitrogen, the coating sample is applied to a glass-made part (1) with a defined layer thickness, and positioned on a heatable testing board (2).  A measuring light beam emitted by a LED (3) is reflected from the sample surface and registered by a photo diode (4).  The sample is irradiated with a light impulse and thus a VUV dose from an Excimer lamp (5) with electronic shutter, similar to an irradiation process in a production system.  When the micro-folding process is initiated after the skin formation, the measuring light is scattered on the now rough surface of the sample, and less intensity on the photodiode is registered.  The folding process is kinetically visible by light measurement within milliseconds (see the Kinetik curve).   The folding process can be monitored visually through a video camera (6).  In the case of a photo-initiator-containing sample, the layer is cured with long-wave UV light from a 365 nm LED (7).  The VUV dose rate and dose is measured by a radiometric sensor (8) with an open sample board.

 All the process parameters can be varied independently.  The measurement process is optimized and automated.
