Surface Tension Test Pens were introduced to give an accurate measurement of graduated surface tension levels. The fluid is applied to the surface or substrate until a satisfactory dyne level is found.
Experience has shown that wetting is normally adequate when a continuous film of test fluid remains intact for 2 seconds. Breaking of the fluid into droplets in less than 2 seconds indicates a lack of wetting and a lower numbered test fluid should be tried. If the fluid remains intact for longer than 2 seconds, a higher numbered test fluid should be tried.
A clean, new cotton applicator should be used each time to avoid contamination of the solutions
ensure the film surface is not touched or contaminated in the areas in which the tests are to be made.
These pens are widely used in PS、PE、PP、PET、PI、PC、NY、CPP、OPP 、PVC etc.
