Akfix E350 is a thermosetting two-part epoxy adhesive. The syringe holds two separate chambers: an epoxy resin (Component A) and a hardener (Component B). Neither component does anything on its own — they are stable in the pack indefinitely. The moment the two are mixed in a 1:1 ratio by volume, an exothermic chemical reaction begins. The resin cross-links into a dense, rigid polymer network that grips the surface mechanically and chemically.That cross-linked structure is why an epoxy bond behav..
