QGY Coating Film Stackability Tester
This instrument is suitable for measuring the resistance to damage of single-layer coatings, such as lacquers and varnishes, or related products, as well as composite coating systems, after they have been fully dried within the specified drying time, when two coated surfaces, or one coated surface in contact with another type of surface, are subjected to compressive conditions.
QGZ-24 Automatic Paint Film Drying Time Tester
Determining the Drying Time of Paint Films and Putty Films To gain a comprehensive understanding of the drying and curing processes of coatings, an instrument capable of automatically measuring the entire drying period is required. This enables test personnel to obtain accurate and efficient scientific data. The design principle involves using a single-chip microcomputer to control a high-precision stepper motor, which drives a rocker arm equipped with a spherical contact point. Under a specified load and at a constant speed, a stylus performs uniform circular motion on the surface of the coating being tested. By recording the stylus’s trajectory on the coating surface and overlaying it onto a drying-time graph, the complete film-forming process can be evaluated.
