The invention relates to a 2-component polyurethane adhesive, in particular for laminating films, wherein the PU adhesive, based on the total weight of the laminating adhesive composition, (a) contains as resin component at least one NCO-terminated polyurethane pre-polymer having a content of at least 40% by weight of diphenylmethandiisocyanate (MDI), wherein the MDI is 4,4'-diphenylmethandiisocyanate or a mixture thereof with 2,4′-diphenylmethandiisocyanate, and (b) contains as hardener component a polyol mixture comprising at least three different polyols. The invention further relates to the use of the adhesive for adhesively bonding films, to methods for producing composite films, and to composite films bonded by means of the described adhesive.

Low-viscosity, rapid curing laminating adhesive composition

The invention relates to a two-component polyurethane adhesive, in particular for laminating films, wherein the PU adhesive, based on the total weight of the laminating adhesive composition, (a) contains as resin component at least one NCO-terminated polyurethane pre-polymer having a content, based on the total weight of the resin component, of at least 40 wt % of diphenylmethanedi-isocyanate (MDI), wherein the MDI is 4,4'-diphenylmethanediisocyanate or a mixture thereof with 2,4′-diphenylmethanediisocyanate, and 2 to 20 wt % of polyglycol having a molecular weight Mw of 200 to <1000 g per mol, and (b) contains as hardener component a polyol mixture comprising 2, 3, or more different polyols and is free of polyesters. The invention further relates to the use of the adhesive for bonding films, to methods for producing composite films, and to composite films bonded with the adhesive described.

Polyester-free laminating adhesive composition

The present invention relates to adhesives which contain a polyester polyol on the basis of furandicarboxylic acid obtained from renewable raw materials, and to a method for bonding substrates, in particular film-like substrates, using said adhesive.

Polyester polyol-based adhesives on the basis of furandicarboxylic acid obtained from renewable raw materials

A radiation curable adhesive comprising (i) (meth)acrylic monomer(s) and/or oligomer(s), wherein said (meth)acrylic monomers or oligomers comprise 5 to 50 wt % of esters of (meth)acrylic acid with polyetherpolyols having the formula HO&#x2014;((CH)&#x2014;O)&#x2014;X wherein m=2, 3 or 4; n=2 to 50; X=H, linear, branched or aromatic C1 to C12-alkyl, the ester having a molecular weight from 150 to 2000 g/mol; (ii) non-reactive (co)polymer(s) based on unsaturated monomers, wherein said unsaturated monomers are selected from vinyl esters, (meth)acrylate esters and C2 to C8 unsaturated olefins, the (co)polymer having a molecular weight from 5000 g/mol to 500000 g/mol, such adhesive can form a solid adhesive layer after being cross-linked by radiation, the layer, has a non tacky surface but can be adhesively bonded under pressure to a second layer of the adhesive.

Dry bonding acrylate adhesive layers

Adhesive for adhering synthetic and/or metal substrates, selected from liquid or thermoplastic adhesives which have urethane groups in the polymer chain, wherein the adhesive is selected from NCO-reactive adhesives, silane-reactive adhesives or thermoplastic polyurethanes (TPU) and include as a constituent 0.01 to 10 wt. % of at least one compound (H) having a molecular weight of less than 500 g/mol, which compound has at least one sulphonamide group having an SO&#x2014;NH&#x2014;C(O) structure or at least one amidosulphonate group.
