Paint Film Pendulum (Persoz) Hardness Tester

The pendulum hardness tester for paint films evaluates hardness by swinging a pendulum on the surface of the paint film, based on the decay time or number of swings. The energy loss when the pendulum contacts the paint film reflects the material's resistance to deformation. It is used to test the hardness of coatings and inks after drying, guiding formula adjustments and process control.
Selection
When selecting, consider matching the measurement range to the sample hardness, confirm that the pendulum type complies with standards, and check the instrument's leveling adjustment function. Review the friction index of the pendulum axis and verify the validity of the calibration certificate. Choose an appropriate base according to the sample thickness and ensure that the environmental temperature and humidity are controllable.

The pendulum hardness tester tests the scratch resistance limit of varnish.
The pendulum hardness tester measures the hardness of varnish by observing the attenuation of the pendulum's swing on the coating surface, with faster attenuation indicating a softer coating. The scratch resistance of varnish depends not only on hardness but also on elasticity and toughness. Hardness testing sets the basic threshold for scratch resistance.
Use of pendulum hardness tester for paint film curing degree assessment in the laboratory.
The pendulum hardness tester evaluates the hardness of a paint film by measuring the decay time of a pendulum swinging on the surface of the film, where a longer time indicates a harder film and a higher degree of curing.
Pendulum hardness tester measures the damping hardness of powder coatings.
This article introduces the method of testing the damping hardness of powder coatings using a pendulum hardness tester. The test is based on the principle of energy attenuation, where the hardness is reflected by the time it takes for the amplitude of the pendulum to decay as it swings on the coating surface, with a longer time indicating a harder coating.
Pendulum hardness tester measures coating damping hardness.
This article explains how a pendulum hardness tester measures the damping hardness of coatings. The principle involves evaluating the hardness and elasticity of the coating based on the time it takes for the amplitude of a pendulum's swing to decay on the coating surface. A longer decay time indicates a harder coating.
