Flash breaker tape

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. They are available in various colors and thicknesses for either higher conformability or greater tensile strength.

Product features:

  • Excellent adhesion on mold surface, even with release coat applied
  • Temperature resistant up to 220 °C
  • Easy removal without residue

Fixation of resin infusion profiles

Our selected double-sided tapes are a trusted solution for fixing plastic resin infusion channels to the resin distribution net. They can be applied quickly and reliably, which leads to a more homogenous resin distribution. We have tapes with different levels of adhesive on each side for better removability.

Product features:

  • Good immediate adhesion

  • Trusted solution for blade production

Holding of Vacuum Spirals

Vacuum spirals
Vacuum spirals

There are several methods to form the vacuum channels. If you want to fixate vacuum spirals to the mold, then choose one of our double-sided tapes. The tape will need to bond well to the mold as well as the vacuum spiral so that there is no displacement during mold preparation and resin infusion. Using a tape that can be removed without leaving any residue reduces the time needed for the next mold preparation cycle.

Product features:

  • High immediate adhesion

  • Good removability

Layer Fixation

First layer fixation
First layer fixation

The blade consists of numerous layers of glass fiber. Our customers use different methods in order to prevent the web from slipping into the mold during layup. At the edge of the mold, tesa double-sided adhesive tapes can be used to fix the first layer as well as the following layers to each other. Which product is used depends on requirements for removability and temperature resistance. Please contact us for more information.

Product features:

  • Very good tack
  • tesa® 51960: Residue-free removable
  • tesa® 51960: Temperature-resistant adhesive
