Labels for rough surfaces

The labels for rough, porous and structured surfaces must be equipped with special adhesives which stick safely to substrates difficult for adhering. Here the basis of the chosen adhesive is essential, which basically consists of acrylate or rubber. Special adhesives combine acrylate and rubber to a hybrid adhesive to use the advantages of both components.

These constant high-performance labels offer the best possible reliability, whereas also oily and dirty substrates can be safely labeled.


The key features of labels for rough surfaces

  • Suitable for parts of grey/white cast iron and powder coated substrates
  • High mechanical resistance also for outdoor applications and in the area of chemicals and solvents
  • High abrasion resistance with suitable thermal transfer ribbons for the thermal transfer printing
  • Very high adhesive power also on dirty and oily substrates
  • Optimization of processes due to the automation of material and product flow by mechanical dispensing
  • Labeling of still hot work pieces possible
  • Additional functions like e.g. perforations, sets or special cut-outs possible
  • Plain labels in individual formats and special forms

Functions and advantages – precisely tailored to your requirements for the labeling

The labels offer the best possible flexibility and will be adjusted individually to the customer’s requirements. This happens by using suitable special materials, individual die-cutting forms and premium adhesives by leading manufacturers like e.g. Avery, 3M, Flexcon, and Tesa.

The labels can be inscribed directly as required in variable amounts with current data at the site, by that the storage and the management of numerous labels may be dropped or reduced.

Some products to be labeled must be labeled when still hot. Additionally, other products can have a very rough, structured or dirty or oily surface, for that there are existing solutions for the safe and long-term labeling.

Our upscale and accurate processing with most modern die-cutting technologies guarantees the highest precision and reliability for the label application. Thus even plain labels with adhesives which are difficult to process can be processed mechanically very well, which increases the user efficiency in the long term.

Frequently Asked Questions

These labels can be applied for example in the following branches and areas:

  • Vehicle construction (public transport, freight transport, ships and train construction)
  • Medical products (cast iron cases and forging)
  • Car manufacturing (electric motors, transmissions, cardan shafts, and rolled metal)
  • Mechanical engineering (engines, machines, and machine tools)
  • Electric tools engineering (tools, home appliances, office machines etc.)

Here barcode labels, type plates, rating plates as well as caution- and warning labels for the substrates difficult for labeling in demanding environments will be increasingly used. These high-performance labels will be adhered not only on cast iron and forging, but also onto plastic parts with structured surface, metal surfaces outdoors, and valves as well as in vehicle body construction. Also there are solutions for rough surfaces with a low surface tension.

The extreme environments, like for example in the engine compartment or on the cast iron parts of a transmission, impose highest demands  on upper materials, imprints and especially on the applied adhesives. For the secure labeling of rough and structured surfaces mostly rubber based adhesives are required, whereas hybrid adhesives for especially difficult applications are also possible. The rubber is marked by its especially viscous structure and thus is well suited for the connection with rough surfaces. Here natural as well as synthetic rubber come into action, because both can permeate very well in rough indentations. Additionally, the adhesive formula and especially the application weight can be adjusted to reach long-termed balance between adhesion (the ability of two parts to stick to each other with boundary layers) and cohesion (internal cohesion of the adhesive). Always focusing on the goal to ensure the labeling of a product for the long term.
