High Performance Tapes for Wind Energy
There are many applications for tesa adhesive tapes during the manufacturing of wind turbine blades. The performance of tesa tapes, with their easy and clean handling, provide many advantages supporting the efficiency of the whole production process.
tesa 4810 single sided PTFE laminated glass cloth tape
tesa 4810: single-sided PTFE laminated glass cloth tape with silicone adhesive
Application: Self-adhesive film for large area surface masking for permanent anti-stick surface inside the mould.
Benefit: Once applied speeds up time-consuming mould preparation with release waxes or liquids.
tesa 4613 single sided multipurpose cloth tape with natural rubber adhesive
tesa 4613: single sided multipurpose cloth tape with natural rubber adhesive
Application: Bundling of tubes, short term holding of films where temperature and residues are not crucial.
Benefit: Aggressive high tack even on rough surfaces, easy to tear.
tesa 51960 double sided tape fabric reinforced
tesa 51960: double-sided tape fabric reinforced PP backing and acrylic adhesive
Application: Temporary holding of vacuum spirals around the mould.
Benefit: Residue free removable, high coating weight to the spiral side prevents lifting off during RIM preparation.
tesa 61122 and tesa 61123: single-sided tape with PET backing and silicone adhesive
tesa 61122 and tesa 61123: single-sided tape with PET backing and silicone adhesive
Application: Temporary masking during resin infusion. Easy mould cleaning from flashed resin after resin infusion.
Benefit: Excellent adhesion on low surface energy products; differing in thickness offers either higher conformability or greater tensile strength.
tesa 4970 and tesa 4914 double sided tape with non woven carrier and acrylic adhesive
tesa 4970 and tesa 4914: double sided tape with non woven carrier and acrylic adhesive
Application: Fastening of resin infusion profiles onto the resin distribution net; tesa 4914 for more crucial net surfaces. Enables faster assembly and more homogenous resin distribution.
Benefit: Excellent positioning of resin profiles. Prevents contamination of later blade structure with natural rubber.
tesa 54994 single sided PU filmic tape with acrylic adhesive
tesa 54994: single-sided PU filmic tape with acrylic adhesive
Application: Permanent protection of leading edge wind generator blades.
Benefit:Longer protection of the most stressed area of the rotor blade. Clear outdoor grade. Will not stain, lift or dry out. Approved by major OEMs and Tier 1s.
tesa 7070 ACXplus double sided acrylic foam tape with acrylic adhesive
tesa 7070 ACXplus: double-sided acrylic foam tape with acrylic adhesive
Application: Permanent mounting of air distributaries (gel coat to plastic or metal).
Benefit: Faster process time, no pot-life to be considered vs. liquid glue, available as die-cut. For permanent bonding solutions when ever thermal elongation needs to be considered.
tesa 50530 single sided polyolefinic protection film
tesa 50530: single-sided polyolefinic protection film
Application: Surface protection during outdoor storage and transportation.
Benefit: Offers cost savings due to reduction in rectification and final repair.
tesa 6930 laser engravable single sided acrylic film
tesa 6930: laser engravable single-sided acrylic film
Application: Permanent marking of lot numbers enables tracking of rotor blades.
Benefit: Flexible marking and die-cutting. Withstands heat and abrasion.
tesa 4657 single sided premium coated cloth tape with thermosetting natural rubber adhesive
tesa 4657: single-sided premium coated cloth tape with thermosetting natural rubber adhesive
Application: Temporarily sealing nacelle cleaving before final assembly.
Benefit: Balanced adhesion level for different substrates with residue free removability. Withstands outdoor environment up to six months.
tesa 60950 anti slip tape
tesa 60950: anti slip tape
Application: Anti slip surface provides secure and safe footing inside and on top of the nacelle.
Benefit: Very good adhesion on demanding surfaces. Saltwater resistant. No shrinkage after application.
