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

• standard models available:
• - BK3: 6 tracks, 3 selectable speeds: 6, 12 or 24 h.
• - BK6: 6 tracks, each pair of tracks is driven by anindependent 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 o Simple maintenance & easy to clean
• Standard delivery: recorder, set of 6 (or 10) needles, pack of 6 (10) glass strips 0240 V/50 Hz or 110 V/60 Hz.
