Loctite 3425/50ml – Structural Bonding 2k Epoxy
Loctite EA 3425 structural bonding – 2K Epoxy, multiple purpose bonder, excellent for bonding metals, for large surfaces.
Loctite EA 3425 is a two component, high viscosity, thixotropic epoxy adhesive which cures at room temperature after mixing. It is a general purpose, non sag adhesive which develops high strength on a wide range of substrates. The thixotropic properties enable this adhesive system to bond rough vertical surfaces made from metal, ceramic, rigid plastics or wood through gaps of up to 3 mm.
