Drying Time Recorder

A reliable apparatus to test the drying time or gelation behaviour of many paints and coatings, applied onto a glass strip of 300 x 25 mm (12” x 1”) by means of our cube applicator. Hemispherical needles travel on these test tracks, over a selected time: 6, 12 or 24 h. The drying time stages can be easily assessed with the graduation scale (according to traverse speed configuration):

1. Evaporation of solvent: deep pear-shaped impression
2. Sol-gel transition: continuous track
3. Surface dry: interrupted track
4. Final dry time, the needle no longer penetrates the film

Features

* 3 standard models available:

- BK3: 6 tracks, 3 selectable speeds: 6, 12 or 24 h.
- BK6: 6 tracks, each pair of tracks is driven by an Independent motor, this allows different test start times. 1 speed: 12 h.
- BK10: 10 tracks, same as BK6, 1 speed: 12 h.

* Special speed combinations with 6, 12, 24, and 48 h. also possible, to be specified when ordering
* Optional 6 x 5 g. brass weights to increase test pressure
* Simple maintenance & easy to clean
* Standard delivery: recorder, set of 6 (or 10) needles, pack of 6 (10) glass strips
* 240 V/50 Hz or 110 V/60 Hz*
