Feature(may vary by option.)
●1.According to ASTM D 4212 (Standard Test Method for Viscosity Cup Immersion).
●2.Quickly measures the viscosity of liquids such as paint, lacquer, varnish, syrup and oil.
●3.Viscosity is expressed in Zahn seconds which are correlated to viscosity in centistokes.
●4.Mainly in order to maintain the stability of the viscosity of the product in the process of use, so that the viscosity is always maintained at the set range to protect the color of the product effect.

Description
Scope
This test method covers the determination of viscosity of paints, varnishes, lacquers, inks, and related liquid materials by dip-type viscosity cups. This test method is recommended for viscosity control work within one plant or laboratory and should be used to check compliance with specifications.
- Zahn Viscosity Cup—No. 1 through No. 5 Zahn viscosity cups made of corrosion- and solvent-resistant materials. The capacity of the cup is 44 ml.
- Viscosity is a measure of the fluidity of a material. Viscosity data are useful in the determination of the ease of stirring, pumping, dip coating, or other flow-related properties of paints and related fluids.
- This type of cup is used to measure viscosity because it is easy to use, robust, and may be used in tanks, reservoirs, and reactors.
V = K ( t - C )
Choose the proper cup so that the time of efflux will be between 20 and 80 s.
The range of 20 to 80 s covers the most linear portion of each cup. In addition, below 20 s, turbulent flow may cause additional inconsistencies. Above 80 s, factors that may impact on the precision include; loss of solvent (and therefore varying viscosity), “skinning” of the liquid in the cup, intermittent flow.
- No. 1 with the smallest orifice is used for determining the viscosity of thin-bodied materials;
- No. 2 is for use with clears, lacquers, enamels, and press-side adjustment of flexographic inks;
- No. 3 and 4 are for use with more viscous paints and inks (No. 3 for manufacturing of flexographic inks);
- No. 5 is used for silk screen inks.

1Using a suitable solvent to wipe clean，when before or after the cup be used. |
2Put the cup into the container body 1- 5 minutes, to achieve thermal equilibrium of the cup body, then put the cup body vertical lift from the feedstock, the action should be fast and stable. |
3Time keeping when the upper end of the cup leave from the surface of Liquid,and liquid should be kept out of the cup vertically, with the surface distance of not more than 150mm. |
4Stop timing when the first breakpoint occurs, and the difference between the two measured values should be less than 5% of the average. |
