Extended range of test kits for surface energy levels.

Dyne Technology, a specialist in plasma and corona surface treatment technology for manufacturers in the plastic and rubber industries, has extended its family of test kits and now offers a new range containing up to 12 bottles of test fluid in one carry case.

Dyne states the extended range has been adopted to offer engineers a wide range of Dyne levels within the sets to use on a wide range of materials with different surface energy levels.

The new range of kits includes the QA Set, which has been adapted to enable users to purchase one kit that holds the complete range of Dyne test fluids from 30mN/m (Dynes/cm) up to 72mN/m. It is said to enable the user to have the full range of Dyne test fluids on hand, thus allowing measurement of a wide range of materials with different surface energy levels at the same time.

The company states its Dyne test method plays a big part in process control for many manufacturing companies, especially in the automotive and printing industries where surface energy/tension levels must be controlled in order to maintain quality standards.

The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues and coatings. When applying the Dyne test fluid, if it remains as a film for three seconds, the substrate will have a minimum surface energy of that ink value, expressed in mN/m (Dynes). Should the Dyne test liquid reticulate or draw back into droplets in less than one second then the surface energy of the substrate is lower than that of the liquid itself. The exact surface energy (Dyne level) can be determined by applying a range of increasing or decreasing values of Dyne test ink.

Also in the new range is the 'Self Select Kit' for users who want to build their own kit, the 'Standard Kit' and a 'Value Set'.
