WEST SYSTEM® 407 Low-Density Filler

WEST System 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. Low-Density Fairing Filler filler is reasonably strong on a strength-to-weight basis. You can blend it into any WEST System 105 Resin/20x Hardener combination, G/flex Epoxy 650, or G/5 Five-Minute Adhesive. Blended with epoxy, it will cure to a dark red/brown color.
