LOCTITE 3423/50ML – Hysol 3423 A7B 2K Epoxy

Loctite 3423/50ml – Hysol 3423 A7B 2k Epoxy

Loctite EA 3423 structural bonding – 2K Epoxy, multiple purpose, excellent for metal, good humidity resistance.

Loctite EA 3423 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. When cured, the adhesive can be sanded to a smooth finish.
