West System 409 Microspheres Blend 100g

A high Density blended filler consisting of loose chopped glass and other fillers, intended for small semi structural repairs, filling voids, or small scale impact damage to glass fibre laminates. The finished repairs are incredibly strong, tough and resilient. When mixed with West System epoxy at a ratio of approximately 25% by weight, the result is a thick paste that can be carefully stippled into place with PVC tape or peel ply to give a smooth finish to the repair. Typical uses include deep void repair due to osmotic blistering; damage to rudder, centreboards and hard edge impacts.
