Viscosity, in the industry of paints, is an important method to measure its thickness, which is crucial as viscosity decides that whether paint requires being applied using a sprayer, roller, brush, or more high tech tool application. It is also required to know to apply the paint evenly and correctly on uneven surfaces. Viscosity cups have a “cup” that holds a specific amount of paint and a long handle for keeping the paint steady in the cup while the viscosity is measured with a stopwatch. At the bottom of the cup is a small “precise size” hole, cup size dependent, that allows the paint to stream through until there is a “first” break in the . The necessity of measuring paint viscosity is well known and there are several methods using a rotational viscometer. To truly get a firm grasp on how paints will perform at any given temperature . These are primarily used to measure paint viscosity to ensure conformity to military specifications. Consistometers also work well for many food applications such as syrups, jellies, and sauces, as well as cosmetics. . A glass capillary viscometer is used in conjunction with test methods which conform to a particular ASTM.
ASTM viscosity testing can be used to analyze either general paint characteristics or fluid conditions at certain steps in the painting process. The variety of tests available ensure that viscosity parameters can be measured as a simple quality control operation or as a defining characteristic of the paint system. Using the correct test enhances the quality of the overall . The SI unit used in this test method for kinematic viscosity is mm 2 /s, and the SI unit used in this test method for dynamic viscosity is mPa
