Coating Viscosity Flow Cup

The viscosity of paint is determined by measuring the time it takes for the paint to completely flow out of a small hole at the bottom of a viscosity flow cup. The longer the time, the higher the viscosity. It is used for on-site rapid testing of paint fluidity to guide dilution and application.
Selection
Select the corresponding flow cup based on the viscosity range of the coating. Choose stainless steel or plastic material considering the solvent corrosiveness of the coating. For routine testing, use a 2mm aperture; for high viscosity, opt for a 4mm or 6mm aperture.

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.
Application of Desktop Viscometer Cups in Batch Sample Screening at Quality Inspection Centers
This article introduces the application of desktop viscosity cups in batch sample screening at quality inspection centers. Viscosity cups estimate viscosity by measuring the outflow time of fluids, making them suitable for rapid screening.
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.
