Barrier coatings

The invention is a composition made by mixing a multifunctional acrylate with an aminofunctional silane and an ethylenically unsaturated acid to form a reaction product, optionally dissolved in a solvent, characterized in that the multifunctional acrylate has a molecular weight of from about 100 to about 3000. The composition can be coated on a substrate, then optionally exposed to moisture and treated to initiate a free radical reaction. The invention can be applied to a variety of substrates used in packaging applications. The reaction mixture can further be cured by heating in the presence of moisture. The free radical reaction can be initiated by electron beam irradiation, ultraviolet radiation, gamma radiation, and/or heat and chemical free radical initiators.

Silicone/multifunctional acrylate barrier coatings

A composition which provides gas, flavor, and aroma barrier to substrates, where the composition is formed by mixing an ethylenically unsaturated acid, a bis-silane and a polyamine.

Alkylenimine/organic barrier coatings having bis-silane additives

The invention is a laminate structure made by coating at least one side of a substrate with a laminating adhesive, bringing a coated side of said substrate into contact with a second substrate to form a multi-layer film, and treating said multi-layer film with a free radical initiator, wherein said laminating adhesive is the reaction product of a multifunctional acrylate, an aminofunctional silane, and an ethylenically unsaturated acid, optionally dissolved in a solvent, wherein the multifunctional acrylate has a molecular weight of from 100 to 3000.

Silicone containing laminate adhesive

A process for treating a surface of a substrate to improve the oxygen, carbon dioxide, flavor and odor gas barrier properties of the substrate with an organic acid having at least two acid substituents selected from the group consisting of a polybasic carboxylic acid, a polymer of an unsaturated carboxylic acid and a co-polymer of an unsaturated carboxylic acid, by applying the acid on to the substrate to form a layer, and exposing the layer to moisture. A variety of other types of additives may be included in the coating applied to the substrate with the acid including compounds of the formula R X Si(CH ) Y, a condensation catalyst, a solvent, and/or a filler.

Barrier coatings using polyacids

A method of laminating two substrates by coating at least one side of a substrate with a laminating adhesive, bringing a coated side of the substrate into contact with a second substrate to form a three layer film, and treating the three layer film with a free radical initiator. The laminating adhesive is formed by mixing an ethylenically unsaturated acid, a bis-silane and a polyamine, and the polyamine optionally can have a crosslinker reacted therein.
