Although the various stages of drying and curing in films are perceptible, defining them in terms of chemical and physical principles is challenging. To assess them effectively, instrumentation under controlled conditions is necessary.

Application of Drying Time Recorder QualiDTR-I

Drying Time Recorder QualiDTR-I

Qualitest offers a versatile drying time recorder to quantify the different stages of film curing and drying, ensuring reproducible results and maximum efficiency:

This reliable Drying Time Recorder, tests the drying time or gelation behavior of various paints and coatings, applied onto a 330mm×24mm glass strip using our cube applicator (Hemispherical needles traverse these test tracks over selected time intervals: 6h, 12h, 24h, and 48h.

Drying Time Recorder QualiDTR-I

The drying time stages are easily evaluated using the graduation scale (according to traverse speed configuration). The total test duration is displayed on the LCD screen.

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

Procedure

Coat the glass panels using the QualiDTR-ACC-203 Cube film applicator (order separately)
The drying of the paint starts. If you prepare multiple panels at different times, note the time when the drawdown was made and add it to the time the sample is in the recorder
Place the recorder bridge in the starting position and put the panels in place
Place needles on the sample panel and select the speed by adjusting the speed switch
Turn on the recorder– the unit will automatically switch off at the end of the test
Evaluate the results
