AFNOR viscosity Cup for varnish

The AFNOR viscosity cup determines viscosity by measuring the time it takes for a specific volume of liquid to flow out through a small hole at the bottom of the cup. It is used in industries such as coatings and inks for on-site rapid testing of fluid flowability. The operation is simple, and the results intuitively reflect the application performance.
Selection
Select the corresponding cup number based on the viscosity range of the material being tested. Consider the transparency and fluidity of the sample: use a cylindrical cup for transparent liquids and a conical cup for opaque liquids. Verify that the cup nozzle size is consistent with the standard, and maintain a stable ambient temperature.

Drop Ball Method of Impact Testing Machine for Evaluating the Impact Resistance of Varnish
This article introduces the use of the falling ball method with an impact testing machine to assess the impact resistance of varnish. The method involves dropping a steel ball of specified weight from a predetermined height onto a test panel coated with varnish to observe whether the coating cracks or peels off, thereby evaluating its impact resistance.
Wet film thickness gauge measures the wet film thickness of varnish.
The wet film thickness gauge is a mechanical tool used to measure the thickness of liquid varnish coatings. It operates by rolling the gauge so that the tips of its teeth contact the substrate and leave marks. The thickness value is then obtained by the operator reading the scale of the first tooth that becomes coated with the varnish.

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.
