Abstract

A 2-cyanoacrylate composition useful as an adhesive contains a Lewis acid metal salt comprising a metal such as aluminum, gallium, indium or thalium, and the conjugate base of an acid such as a monohalo-, dihalo- or trihalo-acetate (e.g. aluminum trifluoroacetate salt). A clathrate such as a crown ether is also present.
