Drying Time Recorders
A reliable apparatus to test the drying time or gelation behaviour of many types of paints and coatings.
SHBK3 Drying Time Recorders
The SHBK3 Drying Time Recorder is widely used in the coatings industry throughout the world to help quantify the various stages of the film drying and curing process. A needle carrier holding six hemispherical ended needles travels the length of the six 305 x 25 mm test strips in 6, 12 or 24 hours. Other speeds are available to special order. A time scale on the side cover is graduated to suit the three different travel times.
SHBK6 and SHBK10 Drying Time Recorders
The SHBK6 and SHBK10 Recorders have independently operating tracks allowing tests to be made at different start times. Pairs of tracks operate at the same speed, and a wide range of travel times are available. The standard models are supplied with all tracks traversing at 12 hours, however, alternative combinations of speeds of 6, 12, 24 and 48 hours can be specified at the time of ordering.
A time scale on the front cover is graduated to suit the instrument’s drying time ranges. Each pair of tracks has its own individual operating switch.
Initially the needle passes through the film followed by defined stages in the drying process that can be identified as:
- The needle passes through the film, it recovers to leave no trace, progressing to a pear shape impression, corresponding with the evaporation of the solvent.
- Cutting of a continuous track corresponding to a sol-gel transition.
- The track depth is reducing and becomes interrupted corresponding to a tack-free surface-dry time.
- The needle no longer penetrates the film, corresponding to the final drying time.
Brass weights (supplied as an accessory), each weighing 5 grams, may be used to apply greater pressure on the needles and thus record the through-drying properties of alkyds, varnishes and paints. The BK Drying Recorders will give useful information about the gelation times of many two component surface coating materials, and the properties of such films.
