What is the Difference Between Dynamic and Kinematic Viscosity?

Posted by Hank Levi on Jan 26, 2024 1:55:33 PM

At first glance, viscosity seems like a fairly simple concept. It helps describe how thick a product is, or how well it flows. That's all, right?

In reality, there are several different terms that come under the heading of viscosity. These terms are derived from how the viscosity is measured. When people talk about viscosity, they are talking about one of two things: kinematic viscosity or dynamic viscosity.

It's not easy to find a lot of information on the differences between dynamic and kinematic viscosity. This is my attempt to bring clarity to these two principal concepts.

Do You Use Epoxies, Adhesives, Resins or Coatings?

Have you ever mixed up a batch of epoxy glue and, just before you finished the job, of course, had the mix unexpectedly turn into solid concrete? If you have, you experienced the effect of gel time. This term is a common measurement for products that thicken, cure, gel or harden when mixed. Product such as epoxies, adhesives, resins and coatings all use gel time measurements.
