Efficient solutions for your business

A company and its products are only as strong as the people behind them. We stand behind them with conviction and, when required, with extraordinary ideas. As producers, developers, problem solvers and service providers, we are guided by this maxim. The most important objective for us is to find efficient solutions for the widest possible range of industrial requirements. We are therefore committed to product development – by working with our customers to find the best possible solution.

Based on our coating equipment and decades of experience, we offer interested customers extensive possibilities to realize customer-specific solutions. It does not matter whether you want to provide a new film with a standard coating or have a new coating compound applied to a provided film.

Consulting and development

You will receive - if necessary - support in the formulation of the coating compound by our laboratory (our possibilities are not limited to an "adhesive" application) . We will also be happy to assist you with the selection of raw materials (carrier materials) if required. Any necessary "auxiliary materials" such as silicone paper, masking films or laminate partners are available in great variety. The minimum coating quantity should not be less than 1000m². The total capacity is several million square meters per year. Of course, the contract-coated goods can also be cut or formatted afterwards

Project schedule for customer-specific coating / contract finishing

New developments are always an attempt to find new, more economical solutions by trying something different. Interested parties can expect comprehensive support from us to enable them to quickly take advantage of such new developments. We at CMC Klebetechnik have divided this process into individual sections to make this customer-specific development run as smoothly as possible. Any misguided developments can thus be avoided. Furthermore, the costs remain transparent for all concerned.

Measurement options in the development laboratory

Effective development work is also associated with good laboratory equipment. Along with a modern, generously equipped laboratory, we have a wide range of devices for carrying out measurements and tests. Here is a brief selection:

  • Pilot coating system for manufacturing near-production samples with max. width 270 mm and max. length 100 m
  • Climate cabinet made by Weiss, humidity up to 100% rel., temperature -70 to +180 °C
  • Several heating ovens up to 350 °C for e.g. fast ageing tests
  • Vertical combustion chamber for flammability tests based on UL94-V and IEC 60454
  • Horizontal combustion chamber for flammability tests based on UL94-H and IEC 60454
  • Measuring instrument to determine electrical resistance (electrical conductivity)
  • High voltage test device for determining dielectric strength up to 15 kV AC
  • Various viscometers to determine the viscosity of adhesive solutions
  • Several sets of precision scales
  • Measuring instrument to determine residual solvent content
  • Thickness sensor: Scale division +-1 µm
  • Outside micrometer: Scale division +-1 µm
  • Zwick portal tensile load measuring device; upper limit of load cell 500 N, +/- 0.5% of the measurement, to determine the adhesion force, shear resistance and ductility
  • PH electrode: PH 0 to 14 for measurement of the alkaline or acidic properties of solutions
  • Precision spirit level with scale magnifier (divisions of 0.01 mm), to measure film shrinkage, for example
  • Microscope with digital camera attachment for surface investigations
  • Equipment to determine shear resistance even at high temperature (SAFT test)
  • Kofler block to determine the melting temperature of adhesives and polymers

Film coatings - from experiment to market

How often does it happen that you have a good idea, but not the opportunity to try it out or implement it. This is also the experience of manufacturers who are developing a coated product and do not yet know how big the chances are on the market for it. It's nice when you can simply start a trial with relatively little effort.

Meanwhile, the list of sample coatings, customized coatings and contract coatings carried out at CMC Klebetechnik is very long.

In particular, the opportunity to carry out initial trials on a special pilot coater (laboratory coating system), initially on a scale close to production but nevertheless much smaller, is readily accepted.

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 fiber materials, from insulations for high-temperature superconductors to decorative films for furniture surfaces, from applications in the fuel cell stack to carbon-fiber-reinforced adhesive tapes as replacements for steel cables.

The advantage of the laboratory coater is the short set-up time, the very fast and direct intervention option in the test arrangement, and the possibility of also producing 100m web length once. Especially customers who process web materials themselves and whose machines are five, ten meters long often need sample material that has a certain minimum length.

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

CMC Klebetechnik also offers options on the main coating lines to produce even small quantities on a trial basis. Foil, fabrics, nonwovens or papers can be produced cost-effectively from just a few 100m². For this purpose, the line is rented to the customer on an hourly basis. Of course, the concentrated production and application knowledge of CMC Klebetechnik is available to the customer.

Variants of such contract coating are 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. This is because even if the product is to be coated at a later date by a different coater, decisive parameters can already be analyzed at this early stage of product development (e.g. coating speed).

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