  • Patent number: 9006338
    Abstract: An aqueous resin composition with gas barrier properties contains (i) polyurethane resin having aurethane group and a urea group in a total concentration of 25 to 60% by weight and having a acid value of 5 to 100 mgKOH/g, (ii) a swelling inorganic layered compound (e.g., a water-swelling mica, and a montmorillonite), and (iii) a polyamine compound having an amine value of 100 to 1900 mgKOH/g. The polyurethane resin (i) is obtained by a reaction of (A) an aromatic, araliphatic or alicyclic polyisocyanate, (B) a polyhydroxyalkanecarboxylic acid, and at least one component selected from (C) a C2-8alkylene glycol and (D) a chain-extension agent (e.g., diamine, hydrazine and a hydrazine derivative), and neutralized with a neutralizing agent. The proportion of the acid group of the polyurethane resin (i) relative to the basic nitrogen atom of the polyamine compound (iii) is 10/1 to 1/5 as the equivalent ratio.

  • Patent number: 9006304
    Abstract: The present invention relates to aqueous polyurethane-polyurea dispersions which stabilize a foam—produced by mechanical expansion—without addition of further foam-stabilizing components in such a way that aqueous foams are obtainable which are stable both during temporary storage and during processing, so that they can be applied in the form of foam also by customary application methods and substantially retain the foam structure even after drying.
