Edge and Void Fillers

Use void filler to reinforce honeycomb voids and load-bearing voids. Edge filler strengthens honeycomb edges by preventing sag without adding a significant amount of weight. Aircraft filler is a lightweight, low-density compound that also provides a moisture barrier, adds compressive strength, and hardens as a non-brittle solid to maintain flexibility. Aircraft filler also acts as a moisture barrier and noise dampener for sandwich structures. Stock up on dependable brands, including 3Mand others.
