An adhesive composition, of the 'instant adhesive' type, comprising: (a) from 77 to 95% by weight of monomeric 2'-ethoxyethyl 2-cyanoacrylate; (b) from 3 to 15% by weight of a poly-(C1-5) alkyl acrylate or methacrylate having an average molecular weight within the range of from 400,000 to 600,000; (c) from 2 to 8% by weight of hydrophobic fumed silica; and (d) from 100 to 1000 ppm by weight of a polymerization stabilizer; overcomes a number of disadvantages associated with currently available 'instant adhesives' (such as high volatility, brittle adhesive bond, poor resistance to heat and unpleasant smell) and it has the advantages that it cures rapidly and can be used on porous substrates.
