Surface Tension – Why Testing In The First Place?

Dyne pens- many industries, such as plastic and printing, are using dyne pens to measure the surface energy or surface wetting. They have changed the way printing industries were operated.  Industries today are concerned about the level of quality and consistency they receive or achieve in their film. The traditional method of surface energy wasted a lot of scrap materials, and the process was time-consuming.

Dyne pens

Today, industries are looking for quick and reliable output solutions. This is the reason why dyne pens are a popular method to measure surface energy- cost-effective, affordable, no waste, quick.


Why test in the first place?

The quality and consistency is the king of today’s industry. Like we do not buy car insurance to confirm we are bad drives. We did rather buy it as a protection. Similarly, with the dyne checking methods. The checking methods help pose production to ensure that substrates are properly treated.

Conceptually, we perform surface tension or checking process as a measure to pre-check that surfaces are properly prepared to interface with each other and support “strong adhesion”.

Surface tension is the tendency of a liquid to shrink into a minimum surface area possible. Industries need to achieve accurate surface energy because it is directly related to the ability of a substrate to adhere to ink, coating, or printing. If the surface tension of the liquid molecule is higher than the surface energy of the material, the liquid tends to develop droplets rather than spread out or “wet out”.  If the liquid has a lower dyne level or surface energy level, then the liquid will spread out over its entire surface.


In either case, it is necessary to have an appropriate dyne level. The surface energy of every material is different, and the cohesive result will be based on different factors of the substrate. This is why, surface checking mechanism is done, to check specific levels of energy.

Surface fluid tension or surface tension was introduced to give an accurate measurement of guaranteed surface tension.

For testing, there are varieties of dyne pens available for testing. The pens are equipped with a valve tip. If used properly, dyne pens will provide accurate results. Though the main application of the dyne pens is for the purpose of dyne testing or surface tension check, it has a great number of applications in several industries. It is useful for measuring the level of polymers exposed to flame, corona, or plasma modifications. One of the best things about this pen is they are non-toxic- no chemicals such as formaldehyde and ethanol-based like other methods or pens.


Why need corona treating?

The corona treating process is done to increase the surface energy of plastic films, foils, and paper to improve the adhesion and wettability of inks, coatings, and adhesives.

Corona treating process will increase quality and productivity through strong adhesion, improved print quality, and less scarp.

The key to successful testing is using fresh fluid and quality dyne pens.



The non toxic pens are an effective and efficient way to measure surface wettability or surface energy. Sometimes known as corona test pens.
