West System 407 Low Density Filler 0.15kg

West System 407 is a blended microballoon based filler used to make fairing putties which are easy to sand or carve, but are still reasonably strong on a strength to weight basis. 407 can be blended into any West System 105 Resin/20x Hardener combination, G Flex Epoxy 650 or Five Minute Adhesive. The higher the percentage of 407 in your epoxy mix, the easier it will be to fair. Cures to a dark reddish brown colour.
