The invention relates to a method for preparing an at least partially exfoliated clay. The present invention further relates to an at least partially exfoliated clay obtainable by such a method and to a suspension comprising such a clay, as well to the use of such an at least partially exfoliated clay and of a suspension comprising such an at least partially exfoliated clay. Furthermore, the present invention is also directed to a polymeric composition comprising an at least partially exfoliated clay and/or a suspension comprising an at least partially exfoliated clay.

Method for preparing an at least partially exfoliated clay

The invention relates to a composition comprising a sulfone-group containing resin obtainable by reaction of a polyamine containing at least one sulfone-group with a polyepoxide and optionally a hardener, as well as adhesives and coating compositions comprising said compositions having gas-barrier properties, methods for bonding substrates using said adhesives and the thus obtained articles as well as the use of the compositions described herein as adhesive or coatings having gas-barrier properties.

Sulfone-resin containing gas-barrier adhesive

The invention relates to a method for preparing a hydrophobically modified clay, wherein the clay modifying agent corresponds to a quaternary ammonium based compound. The present invention further relates to a hydrophobically modified clay obtainable by such a method and to a suspension comprising such a clay, as well to the use of such a hydrophobically modified clay and of a suspension comprising such a hydrophobically modified clay. Furthermore, the present invention is also directed to a polymeric composition comprising a hydrophobically modified clay and/or a suspension comprising a hydrophobically modified clay.

Method for preparing a hydrophobically modified clay

The present invention relates to toughened cyanoacrylate compositions.

Toughened cyanoacrylate compositions

The present invention relates to thickened cyanoacrylate compositions, such as those in gel or non-flowable forms. More particularly, the present invention relates to non-flowable cyanoacrylate compositions which can be packaged in a convenient pocket-sized applicator dispenser for use in spreading the cyanoacrylate compositions onto substrates.

Thickened cyanoacrylate compositions

The present invention relates to the use of enzymes and/or whole-cell catalysts for the removal of undesired by-products from crosslinkable preparations.

Removal of by-products from crosslinkable preparations

An activator composition for accelerating hardening and achieving cure-through-volume of cyanoacrylate adhesives) comprising; (a) one or more compounds selected from the group consisting of :(i) pyrazine; or a pyrazine derivative; said pyrazine derivative being pyrazine substituted with at least one electron-releasing group; (ii) pyridine N oxides substituted with at least one electron-releasing group; or (iii) 2,6 pyridines being pyridines substituted in the 2- and 6-positions by substituents, at least one of the substituents being electron-releasing provided that both substituents are not methyl; and (b) a volatile solvent carrier for the compound.

Process for bonding substrates or parts and system including cyanoacrylate adhesive and accelerator composition

This invention relates to toughened cyanoacrylate compositions which exhibit improved peel strengths and fixture speeds. The toughened cyanoacrylate compositions include a toughening agent comprising poly(vinychloride-co-vinyl acetate) and poly(methylmethacrytlate).

An activator composition for the accelerated hardening of cyanoacrylate adhesives, wherein the activator comprises a member selected from the group consisting of: aromatic heterocyclic compounds having at least one N hetero atom in the ring(s) such as pyridines, quinolines and pyrimidines and substituted on the ring(s) with at least one electron-withdrawing group which decreases the base strength of the substituted compound compared to the corresponding unsubstituted compound, mixtures of any of the foregoing with each other, and/or with N,N-dimethyl-p-toluidine, and mixtures of any of the foregoing and/or N,N-dimethyl-p-toluidine with an organic compound containing the structural element, &#x2014;N&#x2550;C&#x2014;S&#x2014;S&#x2014;, such as dibenzothiazyl disulfide. 6,6'dithiodinicotinic acid, 2,2&#x2032;-dipyridyl disulfide, and bis(4-t-butyl-1-isopropyl-2-imidazolyl)disulfide. An activator composition may comprise a solution of one or more activators in a solvent mixture which comprises a volatile hydrocarbon and a cyclic ketone.

Activator compositions for cyanoacrylate adhesives

A cyanoacrylate composition comprising (i) at least one lower cyanoacrylate monomer component selected from ethyl cyanoacrylate or methoxy ethylcyanoacrylate; (ii) at least one higher cyanoacrylate monomer component than 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 (iii) a plasticizer. The higher cyanoacrylate monomer and the plasticizer are chosen from certain ones. The compositions cure to give flexible polymeric materials which are desirably also transparent.
