Product Description
Drying Time Recorder
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*
A reliable apparatus to test the drying time or gelation behavior 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):
- 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
Versatile Multi-Track TestingTest up to six samples independently with the Drying Time Recorder. Each track works autonomously, allowing users to assess multiple paint, coating, resin, or varnish specimens simultaneously. This feature significantly improves testing efficiency and provides comparative curing data for various formulations or batches, beneficial in quality assurance workflows.
Precision Motion and TimingEquipped with a high-accuracy synchronous motor and timer (resolution: 1 minute), this instrument moves sample holders uniformly, ensuring reliability in measuring film drying stages. The selectable speed settingsranging from half an hour to twenty-four hoursaccommodate diverse drying profiles, supporting comprehensive process studies and product development.
Durable, Safe, and User-Friendly DesignBuilt with stainless steel and powder-coated metal, the recorder withstands demanding laboratory environments. Its anodized aluminum sample tray resists chemical attack, while overload and overheat protection systems safeguard both user and equipment. Compact dimensions and manageable weight (approx. 8 kg) make it relocatable and practical in daily lab operations.
FAQs of Drying Time Recorder:
Q: How does the Drying Time Recorder determine different stages of film curing?
A: The recorder uses a precision synchronous motor to move sample holders across the surface at selectable speeds. As the stylus traverses each coated track, changes in trace appearance reveal the curing stages, from initial drying to hard film formation.
Q: What materials can be tested with this device?
A: The Drying Time Recorder is suitable for paint, coating, resin, and varnish films, accommodating various formulations commonly used in laboratory and industrial environments.
Q: When is this recorder typically used during the quality control process?
A: It is employed during the paint or coating formulation evaluation stage and for final product quality control, providing critical information on drying and curing times before products are released or applied.
Q: Where can the Drying Time Recorder be installed?
A: The instrument is compact and designed for laboratory settings, manufacturing facilities, or quality assurance departments requiring precise analysis of film drying behaviors.
Q: What is the process for conducting a drying time test with this equipment?
A: Samples are applied to the anodized aluminum tray and the appropriate speed is selected. The timer activates the motor, moving the sample holders while the drying process is recorded objectively for each track.
Q: How does using this recorder benefit manufacturers and researchers?
A: It provides reliable, reproducible data on curing characteristics, enabling improved formulation, process optimization, and compliance with industry standards, ultimately enhancing product performance.
Q: Is the equipment safe to use for continuous testing?
A: Yes, the recorder features built-in overload and overheat protection, ensuring safe operation during extended tests and high-throughput scenarios.
