Dynes Level :

 
  Technical instruction on how to use Surface tension / Wetability tester :  
 

Dynes/cm or Newtons/meter :
Dynes/cm or Newtons/meter is the unit of force in the centimeter-gram-second absolute system, the force which imparts an acceleration of 1 centimeter per second to a body having a mass of 1 gram.

Dynes Solution :
Dyne solutions have been used to measure wetting and predict adhesive potential of plastics and coated paperboard. This method is widely used to test the treatment level of plastic films intended for printing, laminating and coating. Test results are based on how varying surface tension solutions react when applied to a non-absorptive surface: If a given solution wets the surface, its dyne level is lower than the substrate's; if, instead, it rapidly forms beads, its dyne level exceeds that of the substrate. This method offers adequate precision and replicability for most capability studies, materials research and process control.
 
 
     
 
Sr. No. Treatment level in Dynes/cm Expected quality rating in terms of print or coating adhesion / anchorite
1 Below 32 Very poor printing or coating adhesion. 22.05
2 34 Poor printing or coating adhesion. 17.25
3 36 Fairly good printing or coating adhesion. 13.80
4 38 Good printing or coating adhesion. 10.95
5 40 Very good printing or coating adhesion. 08.55
6 42 Excellent printing or coating adhesion.
