Epoxy Hand Lay-up Systems for Wind Blades

Our hand-lamination systems have been used since the beginning of composite blade manufacture. We offer GL-approved systems with variable cure rates, higher service temperatures, optimized fiber wetting and a wide range of pot lives from a few minutes to several hours, all featuring the mixing ratio for ease of use. Benefits include:

  • Proven for blade lamination, overlaminates and repairs
  • Easy to process
  • Hardeners can be blended to achieve desired pot life
  • Same mixing ratio for all hardeners for ease of use
  • Approval and use by OEMs worldwide make these systems the obvious choice for repair companies

Our new 685 laminating system builds on the success of its proven predecessors, L135 and L235, combining best-in-class processing with user-friendly labeling. It represents a step-change from an environmental health and safety perspective.
