When a surface undergoes
, it gains “surface energy.” This process is called
and this increases a surfaces adherence capability, meaning paint and glues will stick more effectively. The quickest and easiest way to measure
is by using
. Dyne tests come in kits that contain droppers or pens with liquids that have a range of surface energy. If the liquid beads up right away, this means the surface energy is less than that of the liquid. By conducting multiple
you can determine an accurate range for how much surface energy a material has. With that knowledge you can evaluate that surface’s adhesion potential.
More about Dyne Testing
measure surface wettability or adhesion. Dyne is used as a unit of force in the milli-newton per meter system of units. When using
you are capable of
measuring surface tension
in the units millinewtons per meter or dyne per centimeter. There are other ways to calculate a surface’s adhesion properties other than a dyne test, such as
, but this requires expensive equipment.
are a very simple, inexpensive and accurate approach to evaluating the level of activation a surface has undergone.
