West System 402 is a high density blended filler that consists of loose chopped glass and other fillers. The filler is suitable for semi-structural repairs, filling voids and small scale impact damage to glass fibre laminates. The result is a strong, tough and resillient finish.Ã
When mixed with West System epoxy, add 25% by weight of 402 to the epoxy mix. This will result in a thick paste that can be stippled into place with a brush, then held in place with PVC tape or peel ply to provide a smooth finish to the repair.
