At tesa, we recognize the critical role of precision and reliability in the renewable energy sector. With our globally recognized expertise in adhesive technologies, we are committed to innovate the future of wind energy alongside our partners. Our specialized windmill tapes are engineered to meet the unique demands of wind turbine manufacturing, ensuring enhanced performance, streamlined processes, and superior durability. From mold preparation to blade finish, it is our goal to enable shorter cycle times and a higher blade output.
In wind turbine production, the quality of the mold sets the foundation for the entire manufacturing process. We can support the two most crucial steps of mold casting process: mold masking and mold release. 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 mold preparation solutions are designed to streamline operations and ensure perfection from the start. By reducing preparation times and enhancing the durability of molds, we enable manufacturers to achieve higher efficiency and better results.
Optimize your mold preparation with tapes that ensure excellent adhesion, facilitate clean removal, and speed up your manufacturing process without leaving residues.

The lay-up and infusion process is crucial for achieving the strength and integrity of wind turbine blades. Our specialized adhesive products support this intricate process by securing materials in place, resisting high temperatures, and ensuring easy removal without damaging the mold. From flash breaker tapes to fixation profiles, our solutions are tailored to improve productivity and reliability.
Our range of single-sided PET tapes with silicone adhesive are designed for masking applications around the mold during resin infusion. They adhere well to molds treated with release coats, can be removed without tearing, and protect the mold from flashed resin.
