In this example, we are using 1R32A-2 conformal coating-with a starting viscosity around 200 cps-and our thinner type 600 (this will make 1R32A-2 preblend 65).

In the next chart, we look at the relation between solvent addition and viscosity. Dilution and Viscosity: How % of Thinner Affects Viscosity This will increase the accuracy of the measurements taken. For viscosity measurements on-site, it is important to ensure the temperature and humidity conditions are within the range established by the user of the material (e.g. When testing a batch material or developing a preblend, HumiSeal uses 25☌ as the standard temperature condition. As can be seen by the graph, for every 5☌ increase in temperature, there is a five cps drop in viscosity. This will show why it is important to measure viscosity at the correct temperature. To explain the effect of the temperature of viscosity, we will use one of our standard preblend materials: 1R32A-2 PB 65. Temperature and Viscosity: How Temperature Affects Viscosity The lower the number, the less viscous the material, as can be seen by this comparison chart: starting with water at 1 cPs and ending with honey at anywhere between 2,000 – 10,000 cPs. Viscosity is the internal friction of moving fluid and a measurement of the resistance of a fluid deformed by shear stress. We will start with the definition of viscosity.

This is the first in a short series on material viscosity, in which we will review what it is and how to measure it.
