2-Cyanoacrylate Adhesive Compositions Having Enhanced Bond Strength

GB2017716

By:

Adhesive compositions having enhanced bond strength are obtained by mixing a monomeric ester of 2-cyanoacrylic acid with an anionic polymerization inhibitor and from 1 to 30 mmoles per kg. of adhesive of an adhesion promoter of the formula: wherein R' is hydrogen or an alkyl, aryl or cycloalkyl group having 1-10 carbon atoms. Such compositions may be used on a wide variety of substrates and are particularly useful on metals.

Cyanoacrylate Adhesive Composition

Heinz Sieger

A rapid setting .alpha.-cyanoacrylate-based adhesive composition having an improved stabilizer therein. The stabilizer is a sulfamide derivative containing the group

----

Stabilizing may be further improved by using the sulfamides in combination with phenolic anti-oxidants, particularly sterically hindered phenols, without reducing the curing rate of the composition.

Adhesive Composition

US4686247

By:

Ethuo Yosida

An adhesive composition characterized in that the composition is prepared by subjecting finely divided hydrophobic silica surface-treated with hexamethyldisilazane to a heat treatment under a reduced pressure, subsequently treating the silica with an acid gas, and admixing the resulting silica with an alpha-cyanoacrylate.

Stabilisierte Cyanoacrylat-Klebstoffzusammensetzung und Verfahren zur Herstellung derselben

DE3140246

By:

Die erfindung betrifft eine Cyanoacrylate-Klebstoffzusammensetzung, die eine organische oder eine anorganische Säure mit einem pKa-Wert von etwa -12 bis etwa 7 in Kombination mit einem sauren Gas als Stabilisatoren enthält. Der synergistiches Effekt ergibt eine verbesserte Stabilität und Lagerstabilität, ohne daß die Klebstoffeingenschaften nachteilig beeinflußt werden.

Protective Composition for Users of Cyanoacrylate Adhesives

EP0080172

By:

Donncha O'Sullivan

This invention relates to precaution against a hazard in the use of adhesive compositions based on cyanoacrylate monomers. It relates to a protective composition for the skin (especially the hands) of a person working with a cyanoacrylate adhesive or "superglue", and to a method using the composition, for protecting such a person's skin.

Adhesive Composition Containing Alkyl Esters of Cyanoacrylic Acid

This invention related to adhesive compositions containing certain esters of alpha-cyanoacrylic acid and to methods for their use.

Sealant Composition

EP0206707

By:

Rene Jimenez

The invention described herein comprises a two component sealant composition and process fro applying the sa,e for repair of ruptures, holes, cracks, etc., in hoses, pipes, tires, etc. The first component is alpha-cyanoacrylate glue which is applied as a layer covering the rupture or crack and after a very short period the second component, a powder, is applied to the surface of the alpha-cyanoacrylate.
