Alkyl cyanoacrylate compositions and methods for making those compositions, utilizing high purity monomeric starting materials, formed into more viscous oligomers, and combined with a plasticizer and inhibitor to provide a single-container, storage stable medical cyanoacrylate.
The present invention relates to a polymerizable adhesive composition which comprises, at least as one constituent, a cyanacrylate component and which requires a comparitively short time for curing when used on surfaces. The present invention therefore also includes a method for the production of the cyanacrylate component described above, and the cyanacrylate component as such.
A quick-setting adhesive composition comprises a 2-cyanoacrylate and at least one 1,1-disubstituted diene, the amount of said diene being greater than 50% of the total weight of the two components. This composition can be used in place of conventional 2-cyanoacrylate adhesives but has improved impact resistance, peel resistance, heat resistance and water resistance.
An α-cyanoacrylate base adhesive composition comprising 0.0001 to 0.5 part by weight of borofluoric acid (as 100 %) per 100 parts by weight of an α-cyanoacrylate monomer, which composition has improved storage stability.
