 This material, being lighter than aluminium alloys, offered much-reduced centrifugal loads on the hub bearings.This was followed by work on synthetic urea-formaldehyde adhesives and led to the Aerolite range of wood glues, used on the Horsa glider and the de Havilland Mosquito fast bomber and later, fighter.ARL was responsible for developing a number of aeronautical-related adhesives, including Aerolite 306, Aerodux 500, Redux - a metal-to-wood, metal-to-metal adhesive, used on the de Havilland Hornet and Comet, and the epoxy resin Araldite.
