Made to Stick - A General Introduction to Tapes

Business books have adopted terms like "stickiness", "bonding" and "made to stick", although they don't discuss applications in bonding technology. What magic is Pressure Sensitive Adhesive Technology creating in our everyday life? Why are surfaces made to stick and why do some bonds not Survive? A key to making an idea sticky is to tell it as a story. This presentation tells the story of "adhesive tapes", their construction and their applications.

Customised Water-based Pressure Sensitive Adhesives – Exploring fundamentals and possibilities through emulsion polymerisation

Water-based pressure sensitive adhesives are used in several applications in various industries; including labels, packaging, tapes, surface protection, graphics applications, high gloss lamination, etc. These diverse range of applications often requires a tailor-made polymer solution. The flexibility of emulsion polymerisation allows for the design of water-based polymers with a wide performance spectrum, spanning from soft and tacky to highly cohesive and removable.

This presentation elucidates the fundamentals of emulsion polymerisation and explores how adhesive performance can be influenced by factors such as monomer selection, emulsifiers, and process parameters. Furthermore, the impact of post-polymerisation additives such as resins, wetting agents, defoamers, thickeners, and crosslinkers are discussed. The presentation provides insights into how these additives affect the performance and processability of the adhesive formulation.

The Best of Both Worlds – How Silicones Serve as High Performance Adhesives and Release Agents in Tape Applications

The unique properties of silicones have made them become inevitable materials in all industry segments. Their uses range from automotive, through electronic industries as well as the medical segment. The most fascinating fact is that they can be tailorized to even present oppositional effects.

 

This paper will show the versatility of silicones in tape applications and present their use in such adverse fields as adhesives and release coatings. It will present the chemical and physical background of these exceptional properties and the benefits silicones thus give for a variety of uses in this area.

Viscoelastic Properties of High Performance Tapes

All pressure sensitive adhesives have in common that they show viscous and elastic behavior at the same time, making them so-called viscoelastic materials. Which of these two quite different properties dominates depends on the structure of the PSA itself as well as on the outer conditions it experiences.

 

This presentation will give a short summary on what viscoelasticity is, how structure and outer conditions influence the viscoelasticity of a PSA and how this affects its properties and performance.

Polymeric Foams as Backing Material for Technical Tapes

Polymeric foams and polyolefin foams in particular are widely used in the industry to produce a large range of tapes for industrial, household, electronic, medical and construction applications.

This presentation will give a short outline on the production process of polyolefin foams, followed by an overview on physical and chemical properties of such foams. Depending on the density and the composition, the properties can be tailored to meet the requirements of the application, so the foam is suitable for e.g. a sealing tape, a fixation tape, a high performance mounting tape or an ECG electrode.

Particularities which need to be taken into account when producing a foam tape will also be considered.

Polymeric Films for Technical Tape Applications

Polymeric films and paper webs are the most important backing materials for self-adhesive tapes. The backing material of the tape determines its mechanical

properties (like conformability, stiffness and tensile strength) as well as its application-related properties (like thermal stability, UV stabilization and optical properties).

Choosing the best backing material is therefore crucial for the final tape application. This presentation will provide an overview of different polymeric films and paper webs regarding their specific properties and some typical applications. It will also point out features of manufacturing and processing of the backing materials. Additionally, some aspects of cloth and non-woven backing materials will be discussed.

Coating and Drying Technologies in Roll-to-Roll Production - State of the Art Processes and Current Developments for Coating and Lamination Lines

JHT Jakobs‑Houben Technologie GmbH is a renowned manufacturer of coating, laminating and impregnating lines for roll-to-roll production. Since 2001 the company stands for tailor-made machines and components in the coating and converting industry. Regardless of their size – lab, pilot or production scale – JHTs’ machines process paper, film, foils, fabrics, membranes and also metal strips. With our slogan “Together for your process!” JHT underlines the company’s claim: highly specialized technical solutions developed to suit your roll-to-roll production process.

In our lecture, we will present state of the art technologies regarding coating and drying processes in R2R-applications. We’ll address different coating methods – for example roller, knife and slot die coating – to give an overview of advantages and disadvantages for each technology.

However, the best coating is useless without the right drying process. Which is why we will be addressing drying technologies in R2R-production such as convection and laser drying, IR- and UV-curing etc. An overview of current developments and upcoming technologies, including possibilities in JHTs’ technical center, will round off our presentation at this years’ Afera Tape College 2024.

Insight Tape Conversion Technology

For the final users, one of the key advantages of tapes is the ability to do pre-converting in customized designs. Like slitting large rolls into smaller ones fitting the applicators, cross-winded spools to improve efficiency, and customer-specific die-cuts that fit the final design.  With this, the highest level of qualified application process is assured by pre-defining the bonding areas in thickness, width and design. An overview of converting technologies, per tape, will be given: slitting, laminating, spooling, laminating and different die-cutting technologies.

Chemistry of Release Coatings

Most self-adhesive products like labels and tapes require a release coating to protect the adhesive layer prior to its use. The release coating usually comes on a carrier called the release liner. Self-adhesive tapes may have a release layer on the backside. The release performance contributes substantially to the conversion properties of a self-adhesive product and therefore require attention. Today, various release systems are available, dominated by silicone types. The aim of this paper is to explain the main differences between common release systems with a view on chemistry and the required coating and curing technology.

Forget About Your Thumb: How to Test Tape in a More Reliable Way

For sure, testing and evaluating pressure sensitive tapes through a “thumb test” still is common practice. But for sure, there are methods to test tapes in a much more reliable and reproducible way with better, more meaningful results. The presentation will introduce to the most important standard test methods for PSA tapes with a special focus on those methods that deal with the adhesive performance of the tapes: peel adhesion, shear resistance and tack. The measurement principles are described and notes on some important parameters will be given, including discussion of potentials and limits of the tests. In addition, examples for test methods directly related to specific applications will be shown and their link to the results of standard tests will be briefly discussed.
