Is there a reliable source for a viscosity conversion chart/calculator out there?
I am entering the spray finish world. I bought a quart each of Target Coatings EM2000 & EM6000 in satin.
Target Coatings specs are #2 Zahn.
I measured both with a #4 Ford that came with my hvlp system.
Target specs EM6000 @ 35-40 s, #2 Zahn (also saw a 2nd source from TC, 30-35 s #2 Zahn)
I measured 28-30 s, #4 Ford (65 deg F)
Target specs EM2000 @ 35-40 s, #2 Zahn
I measured 18-20 s, #4 Ford (65 deg F)
I used an online calculator to convert #2 Zahn (35-40 s) to #4 Ford (21-25 s)
I looked at some other charts that give various conversions between the Zahn and Ford.
Some were slightly lower, some higher.
It appears my measurements are on the low end of the TC spec for EM2000 and the high end for EM6000
Is this normal for the viscosity to vary across this range based on the manufacturer’s specs?
