Standard Test Methods for Measurement of the Rotational Viscosity of Paints, Inks and Related Liquid Materials as a Function of Temperature

Importancia y uso:

5.1 The viscosity of paint, inks and many related liquid materials is dependent on temperature. It is useful to know the extent of this dependence. One use of such information is to prepare a viscosity-temperature table or curve. Then, if ambient conditions do not allow the measurement of viscosity at the exact temperature stated in a specification or regulation, the viscosity measured at ambient temperature can be used to determine the viscosity at the temperature of interest through the use of the previously prepared table or curve. Viscosity measurements that cover a range of shear rates as well as temperatures could include shear rates associated with paint application or allow extrapolation to such shear rates. This information would enable a producer or user to estimate the effect on application of heating the paint.
