Paint Viscosity Cup

The paint viscosity cup measures the time it takes for paint to flow completely through a small hole at the bottom of the cup, with longer times indicating higher viscosity. It is used for rapid on-site testing of paint flow and application performance, guiding the amount of diluent to be added.
Selection
Select a viscosity cup with the corresponding number based on the viscosity range of the paint to be tested; for high viscosity, choose a cup with a larger aperture. Consider using stainless steel cups for volatile paints, while aluminum cups are suitable for routine testing. Selecting a cup type with a common flow time of 30–100 seconds can help reduce errors.

Handheld viscosity cups are used for rapid assessment of paint viscosity at construction sites.
A handheld viscosity cup is a portable tool used to quickly assess the viscosity of coatings at construction sites. It operates based on the flow-out time method, calculating viscosity by measuring the time it takes for the coating to flow out of the cup's orifice. It is suitable for Newtonian or approximately Newtonian fluids.

Key steps for measuring the efflux time of varnish using a viscosity cup method
This article introduces the method for measuring the outflow time of varnish using a viscosity cup. The principle is based on Poiseuille's law, where viscosity is estimated by recording the time it takes for the liquid to completely flow out from the small hole at the bottom of the cup—longer times typically indicate higher viscosity.
Types and Selection of Paint Viscosity Cups
As a simple tool for measuring the liquid outflow time, the viscosity cup is mainly categorized into various types such as the Tu-4 cup, ISO cup, Ford cup, and Zahn cup, based on standards from different countries and regions. These cups differ in orifice size, capacity, and the types of fluids they are suitable for.
