Drying Time Recorder (4 time scales, 6 tracks)

Product Description

Solvica offers a versatile drying time recorder that helps quantify the various stages of film curing and drying, delivers reproducible results, and ensures the highest efficiency.

This reliable apparatus is used to test the drying time or gelation behavior of many paints and coatings applied onto a glass strip (330 mm × 24 mm), using our cube applicator (BGD 203). Hemispherical needles travel across these test tracks over selected time intervals: 6, 12, 24, and 48 hours.

The drying time stages can be easily assessed with the graduation scale (according to the traverse speed configuration). The total time for each test can be observed on the LCD screen.

Standards

• ASTM D 5895-03
• ISO 9117-4

Technical Specification

Using the Solvica Drying Time Recorder, the operator can easily identify each stage of the drying process.

• 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

A ball tip is placed into the coating, and, using the mathematical formula Distance = Speed × Time, the recorder moves this ball at a predefined speed. As the coating dries, the trace left by the ball on the coating identifies each stage of the curing process. The various stages of drying and curing that occur in films are easy to detect but challenging to define in terms of chemical and physical principles. To evaluate them satisfactorily, it is necessary to use instrumentation under controlled conditions.

• Simultaneous testing of 6 samples – saves time
• Four different speeds: 6, 12, 24, and 48 hours – suitable for any application
• Styli diameter (with rounded tip): 2mm ± 0.05mm (6 pcs)
• Includes 6 stainless steel weights (5 grams per weight) for recording through drying
