Wind Energy

Material efficiency is a key factor in the profitable operation of wind power plants. WACKER products for the bonding, anchorage, insulation, impregnation and protection of wind turbines and their components offer the wind-energy industry a future-proof portfolio for onshore and offshore wind parks.

The blades of a wind turbine are formed by bonding together half-shells composed of different materials.

HDK® pyrogenic silica is used in bonding the rotor blades and in securing the turbine to its foundations. Our integrated production system, with its statistical process control and highly efficient reactor dynamics, delivers a pyrogenic silica that is exceptionally pure.

Benefits:

  • Better performance, stability and handling of the bonding pastes
  • Remarkable long-term storage stability
  • High viscosity, with the formation of non-sag adhesive beads directly upon application
  • Excellent efficiency (less material required; the cured resin is less likely to become brittle)
  • High specific surface area and specific, highly hydrophobic treatment

Re-usable silicone rubber vacuum bags increase the efficiency of making parts from fiber-reinforced plastic composites for wind and sea turbines. ELASTOSIL® C silicone rubber grades are room-temperature-curing, two-part (RTV-2) silicone rubber compounds known for their excellent fidelity of reproduction.

Bags made of ELASTOSIL® C 1200 guarantee more processing runs, less vapor and greater flexibility. Our vacuum bags streamline manufacture of fiber composites by the infusion process.

Silicones are also used for the production of spacers, wedges and bladders, as well as for applying pressure to the composite or for creating hollow structures for rotor blades during the manufacturing process. Re-usability and release properties together with good chemical resistance are the key advantages here.

Benefits:

  • Flexible
  • Self-leveling
  • Longer pot life and curing time
  • Suitable for large surfaces
  • Reusable
