Abstract:
1. A cyanoacrylate composition comprising: (i) at least one lower cyanoacrylate monomer component selected from the group consisting of ethyl cyanoacrylate and methoxycyanoacrylate; (ii) at least one higher cyanoacrylate monomer component in an amount greater than 12% by weight based on the total weight of the combination of the lower cyanoacrylate monomer and the higher cyanoacrylate monomer, and selected from the group consisting of: n-propyl-cyanoacrylate, iso-propyl cyanoacrylate, n-butylcyanoacrylate, sec-butyl-cyanoacrylate, iso-butyl-cyanoacrylate, tert-butyl-cyanoacrylate, n-pentyl-cyanoacrylate, 1-methyl-butyl-cyanoacrylate, 1-ethyl-propyl-cyanoacrylate, neopentyl-cyanoacrylate, n-hexyl-cyanoacrylate, 1-methyl pentyl-cyanoacrylate, n-heptyl-cyanoacrylate, n-octyl-cyanoacrylate, n-nonyl-cyanoacrylate, n-decyl-cyanoacrylate, n-undecyl-cyanoacrylate, n-dodecyl-cyanoacrylate, cyclohexyl-cyanoacrylate, benzyl-cyanoacrylate, phenyl-cyanoacrylate, tetrahydrofurfuryl-cyanoacrylate, allyl cyanoacrylate, propargyl-cyanoacrylate, 2-butenyl-cyanoacrylate, phenethyl-cyanoacrylate, chloropropyl-cyanoacrylate, ethoxyethyl-cyanoacrylate, ethoxypropyl-cyanoacrylate, ethoxy isopropyl-cyanoacrylate, propoxyethyl-cyanoacrylate, isopropoxyethyl-cyanoacrylate, butoxyethyl-cyanoacrylate, methoxypropyl-cyanoacrylate, methoxy isopropyl-cyanoacrylate, methoxy butyl-cyanoacrylate, propoxymethyl-cyanoacrylate, propoxy ethyl-cyanoacrylate, propoxy propyl-cyanoacrylate, butoxymethyl-cyanoacrylate, butoxyethyl-cyanoacrylate, butoxypropyl-cyanoacrylate, butoxyisopropyl-cyanoacrylate, butoxy butyl-cyanoacrylate, iso-nonyl-cyanoacrylate, iso-decyl-cyanoacrylate, cyclohexyl methyl-cyanoacrylate, naphtyl-cyanoacrylate, 2-(2′-methoxy)-ethoxy ethyl-cyanoacrylate, 2-(2′-ethoxy)-ethoxy ethyl-cyanoacrylate, 2-(2′-propyloxy)-ethoxy ethyl-cyanoacrylate, 2-(2′-butyloxy)-ethoxy ethyl-cyanoacrylate, 2-(2′-pentyloxy)-ethoxy ethyl-cyanoacrylate, 2-(2′-hexyloxy)-ethoxy ethyl-cyanoacrylate, 2-(2′-methoxy)-propyloxy propyl-cyanoacrylate, 2-(2′-ethoxy)-propyloxy propyl-cyanoacrylate, 2-(2′-propyloxy)-propyloxy propyl-cyanoacrylate, 2-(2′-pentyloxy)-propyloxy propyl-cyanoacrylate, 2-(2′-hexyloxy)-propyloxy propyl-cyanoacrylate, 2-(2′-methoxy)-butyloxy butylcyanoacrylate, 2-(2′-ethoxy)-butyloxy butyl-cyanoacrylate, 2-(2′-butyloxy)-butyloxy butyl-cyanoacrylate, 2-(3′-methoxy)-propyloxy ethyl-cyanoacrylate, 2-(3′-methoxy)-butyloxy ethyl-cyanoacrylate, 2-(3′-methoxy)-propyloxy propyl-cyanoacrylate, 2-(3′-methoxy)-butyloxy propyl-cyanoacrylate, 2-(2′-methoxy)-ethoxy propyl-cyanoacrylate, and 2-(2′-methoxy)-ethoxy, butyl-cyanoacrylate; (iii) at least one plasticiser component comprising at least one ester group containing plasticiser, the plasticiser component being miscible in a mixture of component (i) and component (ii); the plasticiser component being present in the composition in an amount between about 15 to about 40% by weight of the composition, and the plasticiser component having an Ap/Po ratio in the range of about 1 to less than about 6, provided the plasticiser component does not include pentaerythritoltetrabenzoate as the sole plasticiser.
