SURFACE TENSION TEST FLUIDS

SURFACE TENSION TEST FLUIDS

Surface tension test fluids are introduced by IEEC to give an accurate measurement of graduated surface tension levels. Different fluid samples, denoted to indicate corresponding dyne values are applied to surface of the corona treated substrate. Spread of the test fluid on the test specimen from the continuous film of the fluid to break into droplets is the quantitative measure of surface tension. Surface tension Test fluids sets are available to cover the complete range from 38 to 60 dynes/cm

DYNE TEST MARKER PENS

IEEC’s Dyne Test Marker Pens are the latest in Surface Energy Measurement and are used extensively worldwide. Directions for use: · Select Marker pen with dyne level less than dyne level of substrate’s dyne level · Hold the marker pen tip firmly on substrate to be tested until the tip is saturated with solution. · With soft touch, draw the marker pen across the test sample in two or three passes. Last pass only should be evaluated. · If ink remains wetted out on test samples surface for more than two seconds, repeat this procedure with next higher dyne level marker pen. If drops are formed or tears apart or shrinks into thin line in two seconds or less, repeat the procedure with the next lower marker pen. · The test sample dyne level is the dyne level, which will produce an ink swath that will hold for one to three seconds before de-wetting.
