Mold Masking

When specific liquids are applied to the mold – liquid release coating, in-mold gel coat, or protective paint – the paint edge or large areas outside of the mold need to be masked. The mold surface, the drying temperature, the tape removal method, and many other parameters influence the choice of the optimal masking tape. Our sales specialists will recommend the right tape in order to ensure quick and easy processes.

Mold Release

The idea of using adhesive tapes for mold release instead of liquid release coats is not new to wind blade producers. The goal: Reduce the time needed to prepare the mold for the next blade.

Since the use of common PTFE tapes for this application is limited due to inferior quality, we have developed tesa^® 4800, a new blue premium tape for mold release. It is optimal for edge sealing, crack cover, and full-surface masking in secondary molds. Test it and see for yourself!
