Surface energy and adhesion measurement.

Several quick and simple tests can be used to evaluate the effectiveness of a specific plasma process on a surface. Adhesion and surface energy test methods are particularly useful as they can be applied to both untreated and treated surfaces , allowing for a comparison before and after processing. These tests provide valuable insights into the surface energy of the material being examined.

Before delving into the details of the different test methods, it is important to understand the concept of surface energy.

  • Dyne Test Overview

    Surface energy testing made easy

    Dyne liquids allow rapid assessment of surface energy. Surface energy is the property of a surface arising from unbalanced molecular forces at or near the surface, compared to those in the bulk material, and provides a quick indication of adhesion characteristics and wettability.

    If a liquid is applied to the surface and its surface energy is higher than the surface energy of a material to which it is applied then the liquid tends to form droplets. If the surface energy of the liquid is lower than that of the surface to which it is applied it will spread out or “wet” the surface evenly. This is the basis of the Dyne test.

  • Quick Test Dyne Pens

    Rapid surface testing

    The Quick-Test pens are a convenient tool for checking the quality of plasma treatment on any part. They have a fixed setting of 38 mN/m, which corresponds to the surface energy of a well-treated part. They can be refilled with ink when they run out. To use them, simply draw a line on the part and observe if the ink spreads or beads up. If the ink spreads evenly, the part has been properly treated. If the ink beads up, the part needs more treatment or cleaning.

    The Quick-Test pens are a simple and effective way to ensure the quality of your plasma treatment process and are available off the shelf for next day delivery.

    Quick Test Dyne Pens
  • Dyne Pen Sets

    Accurate surface testing

    We also offer a range of Dyne test pens sets that cover different values of surface tension, from 34 mN/m to 72 mN/m, in 2 mN/m increments. Each pen has a valve tip applicator that prevents evaporation and contamination of the liquid. The pens are easy to use and have a shelf life of up to 12 months if stored properly. The Dyne pen is applied to the surface under study and simple visual observation of wettability is made. Using Dyne pens of increasing surface tension provides rapid identification of the approximate level of the surface energy of the sample,

    All Dyne Pen sets are available off the shelf for next day delivery.

    Dyne Pen Sets
  • Dyne Ink Sets

    Surface energy test inks

    Individual surface energy test inks are supplied in 12ml bottles of varying surface tension from 12mN/m to 105mN/m, or as handy kits with fluids that have a selection of surface tension levels; 28 mN/m, 38, 48, 56, 64, 72 and 105 mN/m.

    By brushing surface energy test Inks of progressively increasing surface tension over a plasma treated surface, it's possible to accurately ascertain the material surface energy, and therefore the improvement in wettability and bonding characteristics compared with an untreated surface.

    Dyne Ink Sets
  • Silicone Test Kit

    Surface silicone contamination solved

Cost effective plasma services.

We understand that plasma technology may not be familiar to you, that’s ok, it’s what we’re here to help with.

We will be happy to discuss your expectations, both technical and commercial, and then undertake some initial plasma treatment trials, totally free of charge, to help you determine if one of our range of plasma treatments could be useful. These preliminary tests are always free of charge. After the initial process development, a treatment plan can be detailed if necessary.

In addition, if purchasing the system immediately is not the most efficient option for you, we offer rental alternatives, allowing you to explore the technology before making an investment. If investment is not part of your journey with us, we also provide fast and cost-effective contract plasma treatment services. Whether you have small, one-off requests or ongoing production needs, we can accommodate them.

To learn more about how we can support you in making the right decision, please select from the options below for detailed information.

Test before you invest.

  • Proof of concept trials

    Proof of concept trials

    Initially, we collaborate with the majority of our customers through complementary and non-obligatory proof-of-concept plasma treatment trials. These trials serve as an opportunity for you to assess whether our range of treatments and equipment, specifically tailored to your requirements, aligns with your needs.

    We have extensive technical knowledge, applications knowledge and of course a wide range of plasma treatment and surface test facilities at our disposal. 

    If plasma treatment isn’t suitable (and sometimes it isn’t!), we can help you to determine that as well, and often, we can suggest alternatives or point you in the right direction.

  • Plasma process development

    Plasma process development

    During plasma processes development, we work hand in hand with our clients to customise a plasma treatment solution that best meets their needs. We undertake in-house or on-site process development for a wide range of new applications, drawing on extensive real-world experience.

    After the initial process development, a treatment plan can be detailed. At this stage, we are generally ready to move forward to quote a specific system/treatment(s) exactly matched to your product, a service which ultimately reduces your risk.

    Plasma Processes:

    • Access to our extensive process library
    • Comprehensive surface testing methods
    • Adhesion and coatings processes
  • Rental options

    Rental options

    We carry a wide range of rental plasma treatment systems in stock at any one time, both standard and customised, and available at great rates for immediate dispatch.

    If an immediate purchase of a system is not the most efficient method for you and should you decide, after trying the equipment and processes, that plasma treatment is right for your product, we even offset part of the rental payment against the eventual outright purchase.

    You can play it safe with us, rent a plasma treatment unit first, then decide. We firmly believe that there isn’t a process or problem that can’t be solved by working together.

  • Contract plasma treatment

    Contract plasma treatment

    We offer a fast and cost-effective contract plasma treatment service for both small one-off requests and ongoing production.

    Contract treatment is a cost-effective way of tapping into the unique benefits of plasma treatment where the cost of capital equipment isn’t justifiable, for example where one-off or short-term contracts have been awarded.

    Our plasma treatment and testing facility is equipped with a comprehensive range of plasma treatment equipment for both cleaning, surface activation, coating and etching.

    Both vacuum and in-line atmospheric plasma treatments can be utilised for contract treatment with fast turnaround times to suit.
