A barrier adhesive for the encapsulation of an (opto)electronic arrangement comprising an adhesive base composed of at least one reactive resin having at least one activatable group, at least one polymer, especially an elastomer, optionally at least one tackifying resin, where the adhesive base has a water vapour permeation rate after the activation of the reactive resin of less than 100 g/m.sup.2d, preferably of less than 50 g/m.sup.2d, especially less than 15 g/m.sup.2d, a transparent molecularly dispersed getter material and optionally a solvent, wherein the getter material is at least one silane having at least one alkoxy group and at least one activatable group.

The present invention relates to an adhesive composition, an adhesive film, a method of manufacturing the adhesive film and an organic electronic device (OED) that are used to encapsulate an organic electronic element. The adhesive composition can form an encapsulant layer having an excellent adhesive property, impact resistance, heat-protecting property and moisture blocking property, so that an OED that includes an element encapsulated with the adhesive composition can exhibit an excellent lifespan property and durability.

A resin composition contains a polyester polyol and a smectite with partially immobilized lithium.

The present invention is directed to gas barrier coating compositions comprising a nanocomposite formed from a polymer and a nanoparticulate clay. The gas barrier coatings are applied to packaging materials such as food and pharmaceutical packaging and exhibit improved adhesion and barriers to gases such as oxygen, carbon dioxide, nitrogen and water vapour.

A resin composition contains an epoxy compound and a smectite with partially immobilized lithium.

The present invention relates to sheet silicate lamellae of a 2:1 sheet silicate with a high aspect ratio, to a method for producing these sheet silicate lamellae and to an aqueous dispersion which comprises the sheet silicate lamellae. The present invention further relates to the use of the sheet silicate lamellae of the invention for producing a composite material, and also to a corresponding composite material comprising or obtainable using the sheet silicate lamellae, more particularly for use as a diffusion barrier or as a flame retardant.

A packer unit to be used in an annular blowout preventer. The packer unit includes an elastomer body including a compound of a nitrile rubber base polymer having a polymer chain, and a quantity of fluorine atoms attached to the polymer chain. The compound includes between 50 and 60% of the nitrile elastomer, between 25 to 35% carbon black, and the rest includes other materials. The quantity of fluorine atoms comprises short-chain fluorocarbon chain molecules The quantity of fluorine atoms displaces at least an equal quantity of hydrogen atoms from the polymer chain when the elastomer body is fluorinated.

A process for the preparation of a film is described, in which a substrate is coated with a coating mixture containing a water-soluble polymer and a layered double hydroxide. The process of the invention is markedly simpler that conventional techniques for affording films having reduced permeability to degradative gases. The films obtainable by the process are particularly useful in packaging applications, notably in the food industry.

An adhesive comprising a getter material and optionally a solvent comprising a catalyst activatable by means of an external stimulus for the reaction of the getter material with a permeate can tolerate brief contact with permeates such as moisture in particular before user application, without any significant impairment of getter capacity.

Disclosed is an EVOH resin composition comprising 2 types of EVOH resins having a different ethylene content and saponification degree from each other. The EVOH resin composition can reduce the occurrence of streaks with retaining gas-barrier property even when applying to vacuum-pressure forming. The use of the resin composition also make it possible to provide a method for producing a container such as cup having excellent gas-barrier property and appearance by vacuum-pressure forming and the like.
