Dyne Test Ink Kit in handy case.

Dyne Technology markets a Dyne Test Ink Kit in a handy carrying case. The kit used for measuring the surface energy of untreated or treated materials contains as standard a range of 6 different test inks 36, 40, 44, 48, 50 & 56 Dynes (mN/m). Alternatively you can specify your own special kit requirements by choosing any 6 inks available in 2mN/m increments from 30-58 mN/m and 72 mN/m.

The easy to use Surface Energy measuring kit contains non-toxic inks, each 20ml bottle has its own integral brush applicator.

This form of measurement is based on the ASTM method for measuring the surface energy of polyethylene film. When the Dyne test ink is applied to the surface, it will either form a continuous film on the surface or pull back into small droplets. If the Dyne Test Fluid remains as a film for 3 seconds, the substrate will have a minimum surface energy of that Dyne test ink value. Should the Dyne test ink reticulate, the surface energy of the substrate is lower than that of the Dyne test ink. The exact surface energy can be determined by applying a range of increasing or decreasing values of Dyne test ink.

The purpose of corona or plasma surface treatment of polymer-based materials is to increase surface wettability through electrical discharge. The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues and coatings. To obtain optimum adhesion, it is necessary to increase the surface energy of the substrate to just above that of the material to be applied. Surface Treatment with either Corona or Plasma results in good wetting of the material over the surface of the substrate and so improves adhesion. For optimum adhesion when printing, gluing or coating on various substrates, it is necessary to obtain a high surface energy. Determining the surface energy can be achieved by the use of Dyne Surface Energy Test Inks.
