Category: Surface Energy

We supply two chemically different types of Dyne Test Inks or Dyne Test Fluids, both covering the full surface energy range from 23 to 72 mN/m. The right choice for you depends on health and safety considerations, material compatibility, and accuracy. Type 1 – ISO Type Dyne Test Inks These inks are formulated to comply […]

Our Relyon Plasma PiezoBrush PZ3 professional set now includes a set of our Dyne Testing Dyne Test Pens as standard. Plasma treatment improves wetting and adhesion by increasing surface energy. The PiezoBrush PZ3 makes this easy to achieve, but the result is not visible to the naked eye. You cannot tell how much wetting has […]

As medical device designers and manufacturers, you often depend on the property wetting, which can lie at the heart of your product’s reliability. Wetting determines two critical things: How well your adhesives, inks, or coatings adhere – ensuring structural integrity and compliance How effectively your coatings perform – from hydrophilic lubricity to hydrophobic protection In […]

Our latest white paper is from Conor Kelly, who answers the question What’s the difference between surface tension and surface energy? In an application where adhesion is required (printing, bonding, sealing, painting, coating, etc), understanding the surface tension and the surface energy of the components – and, crucially, the difference between them – can be […]

Since Dyne Testing Ltd was acquired by Intertronics, our interest in – and understanding of – surface science has expanded past surface measurement to adhesion, adhesive performance and surface treatment. We’ve combined all of our aspects on surface treatment, surface measurement, and surface preparation into one place, alongside some relevant products. Have a look at […]

Today, we’re talking about surface science – specifically about tensiometers – courtesy of Alison. She explains: What tensiometers are able to measure Different types of tensiometers, such as force tensiometer, bubble tensiometer, or optical tensiometer (also known as contact angle meter) Check it out!   You can find out more about specific types of tensiometers […]

Happy new year, and welcome to our first JoinedUpMinute video of 2025. In this video, Alison gives a quick explanation of Dyne pens and measuring surface tension and energy. She covers: Measurement units for surface tension Surface tension versus surface energy How Dyne pens are used to indicate surface energy Have a look!   JoinedUpMinute […]

Our final JoinedUpMinute for 2024 is a speedy overview of wetting, courtesy of Alison. She explains: What wetting is and why it’s important How wetting relates to surface energy How to improve wetting Check it out!   If you want to dive deeper into how to improve wetting, have a look at our video How […]

Earlier this year we acquired Dyne Testing Ltd, a supplier of surface measurement products. Here Peter Swanson, (PS) Founder and Executive Chair of Intertronics, sits down with Alison Fox (AF), Brand Manager of Dyne Testing, to discuss trends in the UK’s surface measurement market. PS: Can you give me an overview the surface measurement equipment user base in the […]

Surface cleanliness is an important topic in many industrial areas, it is especially needed in applications such as coating, painting or printing where something is added on top of the other material. If the surface where the coating is applied to is not clean, the adhesion between the coating and the substrate is typically poor.  […]

We are proud to present you the extension to our Theta optical tensiometer family.  The Attension Theta Flow has automation at an all-time high, accuracy not seen before and remarkable simplicity & ease of use. Together these features make it the most user-independent contact angle meter. It is our solution for more demanding high-end needs, both in […]

The Theta Flex Optical Tensiometer recently won the award for Best of the Best Design at the Red Dot Product Design Awards 2020, making it a winner in the world’s most renowned design competition. The instrument used widely in industrial and academia research was ranked the top product in its category of “Industrial Equipment, Machinery […]

Surface and interfacial tensions are phenomena that effect our everyday lives.  We can find numerous examples where surface tension plays a role.  Take a classic example of a spider walking on a surface of water.  Change that water to ethanol and the poor spider will drown.  Why I hear you ask… because the surface tension […]

Dyne Testing is fast becoming the most well recognised and trusted supplier of Dyne test pens and inks in the UK and overseas for countless applications throughout industry. Offering customers a choice of Dyne test solutions, Dyne Testing strive to provide first class, value for money products and services delivered by a great team of […]

Influence of surface roughness on wettability and how to measure it Many surface modification and coating technologies that are used for optimising wettability and adhesion properties influence both surface chemistry and roughness. Understanding the mechanisms that impact wetting and adhesion by separating these two factors can be key to successful surface development and solving of […]

Dyne Testing has launched a new and extended range of Non-Toxic Surface Energy Tests kits. The new high visibility yellow test inks make it easy to determine the Dyne value of your material. Supplied in a range of standard kits all housed in handy carrying cases; Economy kit – 6 bottles, Standard kit – 9 bottles and […]

We have many customers who use our Dyne Test Fluids to test metal products for surface cleanliness and evaluating the characteristics of their products. The surface energy of metals is much higher than that of most surface contaminants thus, the higher the Dyne level or surface energy (mN/m) also the cleaner the part is. Dyne Testing […]

Three seconds is all it takes to measure the surface energy of your material with our Dyne Test Pens. The low surface energy of polymer based substrates often leads to poor adhesion of inks, glues and coatings.  For optimum adhesion it is often necessary to increase the surface energy of the substrate to just above that […]

Dyne Testing Extend the Range of Dyne Test Kits to Fulfil Customer’s Quality Needs. Dyne Testing has extended the product choice of Test Kits and now offers a new range of Dyne Test Kits containing up to 12 bottles of Dyne test fluid in one handy carry case.  The extended range has been adopted to offer […]

Why is bonding to plastics and rubber so difficult? The age old problem of obtaining good adhesion of paints, coatings, sealants and glues to traditionally hard to bond to materials like polypropylene has challenged engineers ever since its development and introduction by ICI in the late 1930’s. In this whitepaper, Chris Lines explains a few […]
