Abstract
Cyanoacrylate adhesive compositions which employ calixarene compounds as accelerators give substantially reduced fixture and cure times on de-activating substrates such as wood. The calixarene compounds are preferably employed at levels of about 0.1-1% by weight of the composition. The calixarene compounds particularly useful in this invention may be represented by the formula: ##STR1## where R.sup.1 is alkyl, alkoxy, substituted alkyl or substituted alkoxy; R.sup.2 is H or alkyl; and n=4, 6, or 8.
Claims4
In a method of bonding a pair of substrates comprising applying a cyanoacrylate adhesive to at least one of the substrates and joining the substrates for sufficient time to permit the adhesive to fixture, the improvement comprising that said adhesive includes a calixarene compound additive stable to cyanoacrylate monomers.
