Wind-power-plantsBYK now offers BYK-C 8001, a polymer coupling agent, with Germanischer Lloyd certification. This means manufacturers of wind turbines can use the polymer coupling agent without further testing in their glass fiber reinforced epoxy resin systems – an important element in resource efficiency on the globally booming market for wind power.

Certification Undertaken by DNV GL

BYK-C 8001 significantly enhances the mechanical strength of wind turbines and, consequently, the robustness of the rotor blade, so that longer rotor blades can be manufactured at practically the same weight. Since the wind power market – just like the aviation market – only ever uses certified resources and raw materials, BYK decided to apply for BYK-C 8001 to be certified, in spite of the minimal quantities of the additive actually used. This certification was undertaken by the globally recognized Germanischer Lloyd (DNV GL).

BYK-C 8001 leads to substantial augmentation of the mechanical properties of rotor blades for wind power plants on account of the enhanced glass fiber matrix bonding. Special features include the design freedom and universal applicability, as the product is deployed in a liquid state, making dosage easy using amine hardeners, for example.

Additive to Enhance Mechanical Properties by Up to 60%

The BYK additive enhances the mechanical properties by up to 60 percent, since the coupling agent BYK-C 8001 is a copolymer with reactive / surface active groups that optimizes the mechanical strength and the longevity of the fiber reinforced resins in the rotor blades. Results of fatigue tests directly indicate longer blade life. Another special feature is that it is deployable “irrespective of age” with every epoxy-compatible glass fiber fabric – while maintaining consistently high quality in the finished component.

The additive is suitable for use not only in structural components such as rotor blades for wind turbines, but also in comparable systems such as automotive or aviation components.
