The present invention relates to a hot-melt adhesive composition comprising at least one polyester polyol based on Betulin and at least one NCO-terminated compound as well as a method for the production of a laminated article using the inventive hot-melt adhesive composition.

Hot-melt adhesive composition comprising bio-based polyester polyols

The present invention relates to a reactive polyurethane (PUR) hot-melt adhesive, in particular a moisture cross-linking 1K-PUR hot-melt adhesive, wherein the PUR adhesive contains neutralized hollow glass spheres as fillers. The invention also relates to the use of said adhesive for adhesively bonding substrates.

Reactive polyurethane hot melt adhesives containing fillers

The invention relates to a method for bonding metal or plastic substrates, in which the substrate is freed from adhering impurities, a dual-component polyurethane adhesive is directly applied onto at least one substrate without prior application of a primer and the substrates are joined and cured. According to the invention, the dual-component polyurethane adhesive is composed of a component A, containing 1 to 98% by weight with reference to the component A of an oleochemic polyol, 1 to 10% by weight of at least one three-, four- or five-functional polyol with a molecular weight of 90 to 750 g/mol, 2.5 to 60% by weight of at least on aldehyde resin, keton resin and/or keton/aldehyde resin with a molecular weight of 250 to 25000 g/mol, and 0 to 70% by weight of other additives and a component B, containing at least one polyisocyanate, the NCO/OH ratio of the isocyanate component to the polyol component ranging between 1.0 and 2.0:1.
