In general, liquids with higher viscosities will require a larger turbine as well as larger size needles, nozzles and air caps.Ĭheck out the conversion chart below for recommendations on atomizing set sizes based on viscosity measurements.There's nothing Barbie has loved more in her 64 years in the toy world than to keep reinventing herself. The thicker the coating, the longer it will take to flow through the hole, producing a higher reading. Measurements are provided in centistokes, and are expressed in seconds. Step 7: Thoroughly clean the cup with spray gun cleaner and dry it with a soft, lint-free cloth. Step 6: Repeat steps 3 – 5 until you have obtained a consistent reading. Step 5: Write down the number of seconds on the stopwatch. Step 4: Stop the timer when you see the first break in the liquid stream at the bottom of the cup. Step 3: Start the timer as soon as the top edge of the cup breaks the surface of the liquid.

Viscosity refers to the thickness or internal friction of a coating. These instructions pertain to the Zahn viscosity cup. ![]() This article will walk you through how to measure paint viscosity for spraying with an HVLP spray gun.
