1 RAUKANTEX EDGEBANDS FOR ZERO-JOINTS PROCESSING INSTRUCTIONS

2 Increasing demands on design and appearance, coupled with high product quality, play a vital role in furniture production. Whichever requirements our customers have for an edgeband REHAU offers the perfect solution for any requirement with respect to design, function and processing.. Edgebands for zero joints RAUKANTEX pro With 100% polymer functional layer RAUKANTEX plus With colour matched adhesive functional layer RAUKANTEX pure With primer Edgeband with primer 1 SUITABILITY RAUKANTEX zero-joint edgebands are designed for processing on edgebanding machines that work with the CO2 and diode laser, hot-air, plasma or NIR process. To this end, the edgebands are fitted with a functional sub-layer. Because of various influencing parameters in practice (board quality, machine setup etc.), REHAU recommends conducting processing trials on initial use. Laser technology A laser activates the functional layer during laser processing. Hot air technology Hot, compressed air melts the functional layer in the hot air process. NIR technology Thermal energy can be quickly and precisely transferred with near infra-red technology. Plasma technology When a customer uses the plasma process, air plasma emerging from a nozzle melts the functional layer. 2

3 2 PROPERTIES AND DIFFERENTIATION REHAU Edgeband Solutions RAUKANTEX PURE The classic primer edgeband RAUKANTEX PLUS The zero-joint entry RAUKANTEX PRO Permanent zero-joint RAUKANTEX pure, REHAU s tried and tested primer edgeband, is available in all dimensions and decorative designs as before. You will manage to create a seamless joint with RAUKANTEX plus. A coloured adhesive precoated on the reverse side ensures a visual zero-joint on the component. The success story RAUKATEX laser edge continues - with immediate effect under the name RAUKANTEX pro. You can create the perfect invisible joint without compromises with the 100% polymer functional layer. Visual zero-joint Can only be implemented with coloured adhesive Coloured adhesive in standard colours The functional layer is perfectly colour coordinated. Permanent zero-joint EVA / PUR Edgeband adhesion EVA PUR UV stability EVA / PUR Thermal distortion as per AMK (edging) EVA PUR Very good Good With limitations RAUKANTEX pure: RAUKANTEX plus: RAUKANTEX pro: Edges with universal primer for all adhesive systems currently on the market Edges with adhesive-based functional layer adhesive properties are similar to conventional adhesion with respect to post-processing Edges with polymer functional layer for the highest demands 3

4 3 GENERAL PROCESSING INSTRUCTIONS The edgebands to be processed must be acclimatised at normal room temperature (> 18 C). It is recommended to open the boxes. In practice for processing, appropriate suction must be ensured. Subject to the technical instructions on air quality, the air vacuumed off can be discharged into the surroundings local conditions and regulations must be checked in each case. In the case of clean air recirculation, dust particles and gaseous components must be filtered appropriately. The specifications from the machine and filter manufacturer must be observed here. For further instructions and hints on optimal processing of RAUKANTEX edgebands, separate processing instructions specific to the material are available from REHAU. 4 STORAGE If stored properly, RAUKANTEX edgebands can be stored for min. 12 months. For edgebands older than 12 months, however, a processing trial should always be carried out prior to series processing. Recommended storage conditions: - Room temperature (approx. 18 C to 25 C) - Dry - Clean - No vapours containing solvents - Protected from light RAUKANTEX plus (pre-coated with hot melt adhesive on the rear) must not be stored for more than 6 months after delivery. Storage temperature must not exceed 25 C, in order to prevent sticking together of the individual winding layers. 5 PROCESSING PARAMETERS LASER PROCESS The specific energy recommended by REHAU should be used for the processing of RAUKANTEX zero-joint edgebands (plus and pro) with diode lasers. The so-called Espec. [J/cm²] is a value that is determined metrologically and which specifies the required energy per area depending on colour. The Espec. is printed on every roll in the REHAU inside label and available in list form for the specific customer if required for production planning. The specifications apply for straight-line plants. In processing centres (shaped parts), the edges are fed in individually at present (on HOMAG and IMA plants, the Espec. has been usable as with straight-line plants since mid-2015). When using a CO2 laser, the specifications of the required laser power [W] depending on edge width and feed rate must be requested from REHAU. Processing of the RAUKANTEX pro or plus in PVC material using laser technology is not authorised. 6 PROCESSING PARAMETERS PLASMA PROCESS The respective setting for the electrical voltage and compressed air with the plasma process must be requested from the machine manufacturer depending on feed rate and edge width. 4

5 7 PROCESSING PARAMETERS FOR HOT-AIR The specifications for the machine settings are recommendations for processing on straight-line plants when edging 19 mm carrier boards and with the specified feed rates. The main pressure roller should be at 2.5-3bars (approx kg). In case of deviation, the machine parameters must be adjusted in consultation with the respective machine manufacturer or REHAU.

RAUKANTEX pro or plus can also be processed in PVC material using the hot-air process. 8 PROCESSING PARAMETERS FOR NIR PROCESS The NIR technology works in a similar wavelength range to the diode lasers. All RAUKANTEX zero-joint edgebands are geared to this wavelength range. The required power [KW] is specified using programmes already pre-set by the machine manufacturer and must be adjusted if necessary depending on the board thickness and feed rate used. 5
