FIG. 10: Effect of Temperature on Viscosity

The chart in FIG. 10 shows the effect of temperature in reducing two fluids to a sprayable viscosity, between 20 and 34 seconds using a No. 2 Zahn cup.

Note that temperature has more of an effect on high solid fluids than on thin enamels. That is, for the same 10° temperature rise, the viscosity of the high solid fluid is reduced more than the enamel. This means the high solid fluid is temperature sensitive, and you need to take this into consideration when planning your system.

Once the fluid is reduced to about 34 on the chart, vis- cosity reduction begins to level off and temperature will not significantly improve sprayability (it only uses more energy).
