  • Bonding method utilizing cyanoacrylate adhesive having calixarene accelerator
    Patent number: 4718966
    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.
    Type: Grant
    Filed: October 2, 1986
    Date of Patent: January 12, 1988
    Assignee: Loctite (Ireland) Ltd.
    Inventors: Stephen J. Harris, M. Anthony McKervey, David P. Melody, John Woods, John M. Rooney
  • Instant adhesive composition utilizing calixarene accelerators
    Patent number: 4636539
    Abstract: Cyanoacrylate adhesive compositions which employ calixarene compounds as additives 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.The compositions are further characterized by a thickener component, which may suitably be selected from various polymers such as poly(methyl methacrylate), methacrylate type copolymers, acrylic rubbers, polyvinyl acetate and poly(.alpha.-cyanoacrylate) or silicas treated with polydialkylsiloxanes or trialkylsilanes.

  • Novel calixarene compounds
    Patent number: 4622414
    Abstract: Additive compounds useful as accelerators in storage stable cyanoacrylate adhesive formulations have 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. The compounds may be effectively employed at levels of between about 0.1% and 1% by weight of a cyanoacrylate adhesive composition.
