20120015193 | USE OF POLYURETHANE ADHESIVE FORMED FROM POLYESTER DIOLS, POLYETHER DIOLS AND SILANE COMPOUNDS IN THE MANUFACTURE OF FILM/FOIL-COATED FURNITURE - The present invention relates to the use of a polyurethane adhesive in the manufacture of film/foil-coated furniture. The adhesive consists of two components, the first component comprising at least two different polyurethanes which comprise carboxyl groups, and the polyurethanes comprising units derived from polyester diols and units derived from polyether diols, the weight quantity ratio of the sum total of all units derived from polyester diols to the sum total of all units derived from polyether diols being in the range from 1:9 to 9:1, and the second component comprising at least one silane compound reactive toward carboxyl groups. | 01-19-2012 |
20120021213 | ADHESIVE MADE OF POLYMERS HAVING CRYSTALLINE DOMAINS, AMORPHOUS POLYURETHANE AND SILANE COMPOUNDS - A description is given of an adhesive comprising two components, the first component comprising at least two different polymers of which at least one contains carboxyl groups. One of the polymers is selected from polymers which are capable of forming crystalline domains and copolymers of ethylene and vinyl acetate, and the second polymer is an amorphous polyurethane, the quantitative weight ratio of first polymer to second polymer being from 2:8 to 8:2. The second component comprises at least one silane compound that is reactive toward carboxyl groups. The adhesive can be used to produce film-laminated moldings for automobile construction which feature high resistance to climatic cycling. | 01-26-2012 |
20120077044 | BIODISINTEGRATABLE COMPOSITE FOILS - The use of an aqueous polyurethane dispersion adhesive is described for producing biodisintegratable composite foils where at least two substrates are adhesive-bonded to one another with use of the polyurethane dispersion adhesive, where at least one of the substrates is a biodisintegrable polymer foil. At least 60% by weight of the polyurethane is composed of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from dihydroxycarboxylic acids and diaminocarboxylic acids. | 03-29-2012 |
20120148836 | USE OF POLYELECTROLYTE COMPLEXES AS PLASTICIZER BARRIERS - The use of polyelectrolyte complexes as plasticizer barrier is described, in particular those formed from anionic polymer and from cationic polymer, as also are plasticized substrates and production of the same, where the plasticized substrates have been coated with at least one layer which comprises at least one polyelectrolyte complex. | 06-14-2012 |
20120252926 | LATENTLY REACTIVE POLYURETHANE DISPERSION WITH ACTIVATABLE CROSSLINKING - A description is given of an aqueous polymer dispersion comprising at least one polyurethane, dispersed in aqueous phase and having one or more uretdione groups, and at least one solid polyamine with a deactivated surface, said dispersion being useful as an adhesive, coating material or sealant or for producing adhesive, coating or sealing compositions. The compositions can be activated thermally or by electromagnetic radiation. | 10-04-2012 |
20130149510 | USE OF AQUEOUS POLYURETHANE DISPERSIONS FOR COMPOSITE FOIL LAMINATION - The use of aqueous polyurethane dispersions is described for composite foil lamination, where at least 10% by weight of the polyurethane derives from at least one amorphous polyester polyol. | 06-13-2013 |
