MXBON C681 is a specially formulated grade of Cyanoacrylate adhesive for applications requiring high viscosity and resistance to peel and impact. MXBON C681 develops strong bonds on most metals, plastics or rubbers. MXBON C681 is a one-component, solvent-free system and does not require the use of a catalyst, heat or clamps. When a thin layer of MXBON C681 applied between two surfaces comes into contact with atmospheric moisture, a rapid polymerization occurs producing the ultimate bond.
