Abstract: The present invention relates to a polyurethane adhesive, in particular for laminating films, wherein the PU adhesive contains 0.1 to 20 wt % a low molecular weight epoxide comprising at least one epoxide group and at least one hydroxy group, and wherein the epoxide is chemically unbonded or is chemically bonded by means of at least one hydroxy group. The present invention further relates to use of said adhesive for adhesively bonding films, to a method for producing multilayer films, and to multilayer films adhesively bonded with said adhesive.

Abstract: The invention relates to a crosslinkable composition containing reactive polymers selected from among (i) prepolymers having reactive NCO groups or (ii) polymers which have reactive silane groups, optionally further additives and at least one metal-based catalyst, wherein the composition contains up to 10% by weight of retarding substance selected from among cyclic ?-hydroxy ketones and/or triphenols having three adjacent OH groups.

Abstract: The invention relates to a liquid 2K polyurethane composition of a polyol component A comprising at least one hydrophobic polyol with a molecular weight>300 g/mol and a hydrophilic polyol with a molecular weight<500 g/mol, and 1 to 50 wt. % of a powdered molecular sieve as well as a polyisocyanate or an NCO-reactive PU-prepolymer. In addition, a process is described for casting plastic or metallic moldings, particularly membrane substrates, by the use of an inventive 2K polyurethane composition.

Abstract: The invention relates to crosslinking compositions for polyurethane elastomers, made up of a polyol component containing: 30 to 80 wt % polyether diols and/or polyester diols; 10 to 40 wt % polyols comprising at least three OH groups; and to 50 wt % of a monofunctional compound that comprises an isocyanate-reactive group, and an isocyanate component containing an at least trifunctional isocyanate, such that the NCO/OH ratio is intended to be between 0.9 to 1.2. Use of the corresponding crosslinked polyurethane elastomers as molded elements is also described.

Abstract: Moldings based on polyurethane binders containing at least one polyisocyanate, at least one polyol or polyamine, at least one carboxylic acid such as a long-chain fatty acid, and, if appropriate, water and/or one or more amines with one or more fillers have high flexibility if the average particle diameter of the fillers is up to 2.5 mm. The fillers preferably contain particles having round, oval or completely irregular structures. The binder composition and the fillers are reacted at a pressure of 1 MPa to 40 MPa (preferably, at temperatures of from about 60 to about 180° C. for from about 1 to 30 min), and then the shaping apparatus is depressurized. The resultant moldings are suitable for the production of sheets or of semifinished products for the coating of furniture, kitchen worktops, floors, walls, stairs, or ceilings.

Abstract: Reactive polyurethane adhesive compositions are provided which contain one or more polyols, one or more polyisocyanates, and one or more fillers and which have specific caloric values according to EN ISO 1716 of not more than 20 MJ/kg.
