Basic Conditions for Contract Coating

These basic conditions have been drawn up on the basis of a multitude of customised coating processes and the insights gained from them. They are used to achieve the results required as quickly and cost-effectively as possible with the lowest risk for both contracting parties.

Initial coating processes are, of course, trials, the results of which are not always predictable. CMC therefore only ensures appropriate functioning of the coating systems for the type of job concerned, but cannot guarantee the results of the trial in any way.
1. The required properties of the contract coating process must be described by the customer as precisely as possible (detailed list of questions available). Laboratory samples can be used as release samples – the final coating on our systems may show slight differences.
2. Provision of materials must be free of charge to us (free delivery). Returns are made ex works. The customer bears the transport risk. Materials supplied must be clearly marked as such – ideally with the details of the contact in your company. The corresponding safety data sheets must be provided with the supplies, if prescribed.
3. The material provided must be rolled up tightly and without creases and it must not be distorted.
4. The material provided must be firmly attached to the core.
5. The material provided must not be treated with release agents (or this must be disclosed when the order is placed).
6. Safety data sheets (or confirmation that these are not required) must be submitted when the coating material is supplied.
7. Splices must be avoided as far as possible. If they are essential, they must be carried out as follows: material line glued end to end with adhesive over a large surface area on both sides.
8. Splices and faults must be marked with a small red flag on the edge of the tape at the outset, and the end must be marked with a green flag (adhesive tape or similar).
9. A leader of e.g. polyester film 40 - 50 m in length before the material starts can be advantageous.
10. In the case of multiple rolls, the material width must not vary.
11. In most cases, the process creates waste. The smaller the quantities coated, the higher the percentage of waste. A constant residual amount of waste (approx. 2-5%) applies even to larger material lengths and widths.
12. The greater the fluctuations in roll length, width or material properties, the greater the potential waste (discontinuous production).

13. When cutting the material, an appropriate division of cuts should be ensured.

14. The standard core size is 3” (6” possible by agreement).

15. The material supplied must be clearly marked (type number, batch, company name, etc.).

16. The material provided must be clean and packaged in such a way that it is protected against dirt and damage.

17. The tolerances for contract cutting depend on the material and its make-up, and it may only be possible to determine them definitively after a sample cut. The details in the quotation apply.

18. For contract coating processes (and other work, e.g. relining), the following conditions apply in relation to material risk:

19. The material to be coated (adhesive and/or film) is tested in our laboratory for its suitability for coating. If initial coating (processing) is commissioned on one of our systems, the customer exempts CMC Klebetechnik from claims for replacement of the material used if the coating process does not work (CMS undertakes to minimise the damage if problems are detected). Production costs are calculated pro rata. 

Compensation claims for subsequent coating processes are limited to the service provided by us.

20. Any changes to the products or processes used is deemed to be a new commission and notification must always be given.

21. For contract coating processes that are cancelled by the customer after 5 working days or more, the actual costs incurred will be charged. The material supplied must be delivered at least 5 working days before the scheduled date.

22. If conversion work (e.g. UV systems, additional filters) is required on the systems before the trial begins, this is charged at cost. The measures required must be cleared technically in advance. The customer will be given a quotation for this and commissions the conversion work.

23. If the systems are hired on an hourly basis, one hour of preparation and cleaning time must be included. These costs are already included in the daily rate.

24. Disposal of the materials supplied is carried out without incurring costs as far as possible by CMC’s waste disposal company. If significant costs are incurred, they will be passed on without surcharge.
