How to achieve perfect result working with SIBU Design sheets

Fabricating with SIBU Design sheets is a very easy process if the surface for adhesion is right and the correct methods are used for cutting and bonding. The following information represents the three most important steps required for perfect result:

1. The right surface

In order for self-adhesive SIBU Design sheets to stick properly, the surface for application must be non-absorbent and demonstrate surface tension of at least 38 dyn. The tension can be checked precisely using special test pen. In addition, the surface must be free of wax and silicon as these have a separating effect on the adhesive. Prior to bonding, the non-absorbent surface should always be cleaned with alcohol (ethanol or IPA). This removes any dust, grease or oil and raises the surface tension by 4-5 dyn. If patterned sheets are used a special considerations must be taken, the heat sources (heaters, spotlights and etc.) producing over 122° F should be avoided. Certain material possessing limited moisture resistance characteristics should not be used in bathroom or areas with high humidity levels.

2. Correct preparation, cutting and working

If SIBU Design sheets delivered in a rolled condition, they should be unpacked approximately 24 hours prior to bonding and fabrication, laid out flat at room temperature and if necessary, weighed down. Warning! SIBU punch-line 3D sheets should not be rolled. The protective film should only be removed from the sheets after the preparation and installation process have been completed. Cutting, drilling, punching and sawing of the design sheets must always be completed from the upper or patterned side. Detailed information concerning the appropriate tools is available from the SIBU Design representative. Please note! In cases of doubt, please request the technical information sheets from your local dealer before ordering products.

3. Appropriate fabrication technique

The ideal processing temperature is +59° F – +86° F. The better the conditions during the bonding process, the better the adhesion. The effects of dust during bonding must be avoided! Important! When subjected to an increase in temperature of 50° F, products made of thermoplastic material, such as SIBU sheets, expand by around 0.03” per each 39”. Therefore, it is essential that an expansion gap of 0.02”—0.08” be left between the individual sheets and the edging profiles. In the case of high ambient temperatures or marked temperature fluctuations, the expansion gap should be enlarged, or the dimensions of the sheet should be reduced. Press down as hard as possible onto the ground using a rubber roller. The adhesive surface should not be touched during the removal of the protective film and the working process, as dirt has a very negative effect on the quality of an adhesion. If possible, the bonded sheets must be placed under stack pressure for 1-2 hours. SIBUKLE D22 HV adhesive is suitable for the bonding of non-adhesive sheets onto absorbent surfaces. Should other adhesives be used, care must be taken that these are solvent-free. These practical tips are the result of the latest know-how from our application technology department and replace all previous guidelines.

If you have any technical questions please do not hesitate to ask.
