407 Low-Density is a blended microballoon-based fairing filler for WEST SYSTEM® Epoxy. Add 407 to a mixture of epoxy resin/hardener to create a fairing putty. It’s easy to sand or carve this putty once it has cured. The filler is reasonably strong on a strength-to-weight basis. Blended with epoxy to a “peanut butter” consistency, it will be easy to fair. The higher the percentage of 407 in your epoxy mix, the easier it will be to fair. You can blend it into any WEST SYSTEM 105 Epoxy Resin®/200 Series Hardener combination.
