Coating Flow Cup

The paint flow cup measures the time it takes for paint to flow out through a small hole at the bottom, reflecting its viscosity. It is used for on-site rapid testing of the flow properties of paint, controlling the dilution ratio and coating effect during painting applications.
Selection
Select the flow cup with the corresponding number based on the viscosity range of the tested coating, choose a cup body material suitable for the volatility of the coating solvent, select a durable structure that matches the testing frequency in the production process, and verify that the cup orifice diameter complies with the standard specifications.

Articles

The Zahn cup is used for the daily inspection of the viscosity of electrophoretic paint bath solutions.
This article introduces the application of the Zahn cup in daily inspections of the viscosity of electrophoretic paint bath solutions. The viscosity of electrophoretic paint affects coating quality, making daily inspections crucial. The Zahn cup is simple to operate, cost-effective, and suitable for rapid on-site measurements.
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.
Safety Regulations for Closed Cup and Open Cup Methods for Testing the Flash Point of Coatings.
This article introduces two main testing methods for the flash point of coatings: the closed-cup method and the open-cup method. The flash point refers to the lowest temperature at which the vapor of a coating momentarily ignites upon encountering an open flame, serving as a critical indicator for assessing the risk of fire and explosion.
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.
