Adhesive tape development

Efficient solutions for your company

A company and its products are as strong as the people behind them. This is what we stand for with our conviction and, if necessary, with extraordinary ideas. As a producer, adhesive tape developer, problem solver and service provider, we are guided by this maxim. The most important goal for us is to find efficient solutions for the most diverse requirements of the industry. That's why we work intensively on product development - together with our customers. For an optimal solution.

Based on our coating systems and decades of experience, we offer interested customers a wide range of options for implementing customized solutions. It doesn't matter whether you want to apply a standard coating to a new film or have a new coating compound applied to a film provided.

Consulting and development

If necessary, you will receive support from our laboratory in formulating the coating compound (our options are not limited to an "adhesive" application). We are also happy to assist you with the selection of raw materials (carrier materials) if required. Any necessary "aids" such as silicone paper, cover films or laminate partners are available in a wide variety. The minimum coating quantity should not be less than 1000m². The total capacity is several million square meters per year. Of course, the laminated goods can also be cut or formatted afterwards

Project process for customized coating / contract equipment

New developments are always an attempt to find new, more economical solutions by taking a path that has not been taken before. In order to be able to quickly take advantage of such new developments, interested parties receive comprehensive support from us. To ensure that this customer-specific development runs as smoothly as possible, we at CMC Klebetechnik have divided this process into individual stages. This helps to avoid undesirable developments. In addition, the cost framework always remains comprehensible for everyone involved.

Measurement options in the development laboratory

Effective development work also has to do with good laboratory equipment. In addition to a modern and generously equipped laboratory, we have a wide range of facilities for carrying out measurements and tests. Here is a brief selection:

  • Pilot coating system for the manufacture of production-related samples with a maximum width of 270 mm and a maximum length of approx. 100 m
  • Climate chamber, Weiss, humidity up to 100 rel %, temperature -70 ...+180°C
  • Several heating ovens up to 350°C for rapid ageing tests, for example
  • Vertical combustion chamber for flammability tests in accordance with UL94-V and IEC 60454
  • Horizontal combustion chamber for flammability tests in accordance with UL94-H and IEC 60454
  • Measuring device for determining the electrical resistance (electrical conductivity)
  • High-voltage tester for determining the breakdown voltage up to 15kV AC
  • Various viscometers for determining the viscosity of adhesive solutions
  • Several precision scales
  • Measuring device for determining the residual solvent content (volatile solvent measuring device)
  • Thickness sensor: scale graduation +-1µm
  • Micrometer: scale graduation +-1µm
  • Portal tensile tester from Zwick; load cell upper limit 500N, +/- 0.5% of the measured value, for determining adhesive forces, tensile strength and elongation strength
  • PH electrode: PH 0 to 14 for measuring the alkaline or acidic properties of solutions
  • Precision ruler with measuring magnifier (0.01 mm graduation), for example for measuring the shrinkage of films
  • Microscope with digital camera attachment for surface examinations
  • Equipment for determining shear strength even at elevated temperatures (juice test)
  • Kofler bench for determining the melting temperature of adhesives and polymers

Film coatings - from trial to market

How often do you have a good idea but not the opportunity to try it out or implement it? Manufacturers who are developing a coated product and don't yet know how big the chances are for it on the market also experience this. It's nice when you can simply start a trial with relatively little effort.

The list of sample coatings, customer-specific coatings and contract coatings carried out at CMC Klebetechnik is now very long.

The opportunity to carry out initial trials on a special pilot coater (laboratory coating system) on a much smaller scale close to production is particularly popular.

This ranges from weather-resistant film coatings as reflective surfaces to nanostructured conductive coatings used as electrical heaters, from fabric impregnations for composite materials to adhesive coatings for medical fibers, from insulation for high-temperature superconductors to decorative films for furniture surfaces, from applications in fuel cell stacks to carbon fiber-reinforced adhesive tapes as a replacement for steel cables.

The advantage of the laboratory coater is the short set-up time, the very fast and direct access to the test set-up and the possibility of producing 100m lengths of web. Customers who process web-shaped materials themselves and whose machines are five or ten meters long often require sample material that has a certain minimum length.

Two or three hours of sample coating on the pilot coater are usually enough to obtain the first representative samples for a product presentation.

CMC Klebetechnik also offers the option of producing small quantities on a trial basis on the main coating systems. Film, fabric, nonwovens or paper can be produced cost-effectively from just a few 100m². The system can be rented to the customer on an hourly basis. Of course, CMC Klebetechnik's concentrated production and application knowledge is available to the customer.

Variants of such contract coating include the provision of the carrier film, the coating compound or all components. Such initial trials naturally also serve to determine the optimum process parameters in addition to a saleable product. Even if the product is to be coated by a different coater at a later date, decisive parameters can be analyzed at this early stage of product development (e.g. coating speed).

CMC Klebetechnik is therefore not only a manufacturer of technical adhesive tapes, but also a development partner for customer-specific solutions with its own development department.
