403 microfibers adhesive filler is a fine fiber blend. Use it to thicken epoxy blended resin/hardener and create a multi-purpose adhesive. It's most popular use is for bonding wood. Epoxy thickened with microfibers has good gap-filling qualities but will still do an excellent job of wetting-out/penetrating into wood fibers. 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 an off-white color.
