Pendulum hardness of paint film

The pendulum hardness of a paint film is determined by measuring the decay time of a pendulum swinging on the coating surface. The damping of the pendulum is related to the hardness of the paint film, with faster decay indicating lower hardness. This method is used to test the hardness of coatings and inks after drying, thereby controlling the scratch resistance of the coating.
Selection
Select the pendulum type based on the thickness of the material being tested, with a double pendulum used for conventional coatings. Consider matching the instrument specifications to the laboratory temperature and humidity conditions. Refer to product standards to determine the hardness grade range, and compare the decay time ratio between the sample and the standard plate.

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.

This article compares two pendulum methods for measuring coating hardness. The choice of method should consider material hardness and testing conditions, and both methods require standardized calibration and sample preparation.
Key Operational Points and Influencing Factors of Pencil Hardness Method for Determining Coating Film Hardness
The pencil hardness test is a method used to evaluate the scratch resistance of a coating by making marks on the paint film with pencils of known hardness. During the operation, a uniformly cured sample is prepared, and calibrated pencils are used to make marks at a 45-degree angle with a fixed force, aiming to identify the highest hardness grade that does not scratch through the paint film.
