Loctite EA E04 is a grey, 2-part, 1:1 epoxy resin adhesive. It is a very tough material used in structurally demanding applications which require excellent resistance to vibration and impact loading, combined with the benefit of a 3 h cure time but 30 min when heated at +60°C. Particularly suited to the assembly of composite structures made from SMC, DMC or 'wet lay-up' polyesters.
