3M™ Wind Fillers

3M™ Wind Fillers are tough, flexible, two-part epoxy and polyurethane fillers for finishing and smoothing wind turbine blade surfaces and leading edges. They're ideal:

  • During blade manufacturing—to fix surface defects after de-molding or to create a smooth transition between blade halves
  • After transportation—to repair minor pre-installation damage
  • In operation—to repair damage from erosion or impacts with other objects.

3M's specialized line of 3M™ Wind Epoxy and Polyurethane Fillers allows you to finish and repair wind turbine blades at the manufacturing facility or during operations and maintenance, either on the ground or up tower. Multiple chemistries and performance times meet a variety of application needs, while innovative 3M™ Duo-Pak Cartridges and Applicators reduce waste and eliminate messy and time-consuming hand mixing.
