Zahn viscosity cup 02018 series

ASTM D4212chrome steelimmersion

Inmersion cup for the simple and practical measuring of the viscosity of paints, inks, lacquers and other liquids. Manufactured in chromed seel in 5 models (5 to 180 centistokes). The measured kinematic viscosity is generally expressed in seconds (s) flow time, which can be converted to Centistokes (cSt) if the Standard stipulates a conversion method. Viscosity is a key parameter in the behavior of paints both during the manufacturing process and during application. Proper control of this parameter will result in a better use of the paint. Likewise, knowledge of both the application method and application temperature is required when formulating the paint. Adequate viscosity control at low and high shear rates and assessment of any thiroxotropy are also necessary during mixing in order to avoid later undesirable effects during application. Application Calculation of the viscosity by measuring the time needed to flow through an orifice of specific characteristics (seconds). The Cinematic Viscosity is the relation between the absolute viscosity and the density of a fluid
