  • Moisture-crosslinkable polyurethane adhesive for hygiene
    Patent number: 7195692
    Abstract: The invention relates to a moisture-crosslinkable polyurethane adhesive which comprises: a) 70 to 95% by weight of a polyurethane prepolymer obtained by polyaddition of polyols to diisocyanates trimerized as isocyanurates and, b) 5 to 30% by weight of an essentially amorphous poly-a-olefin, the content of free NCO groups representing 1 to 20% by weight of the adhesive. The adhesive according to the invention is used for the adhesive bonding of fixing components of the Velcro type to articles intended for hygiene.

  • Polyurethane-based single-component hot-melt adhesives with improved initial cohesion
    Patent number: 5922805
    Abstract: The invention relates to polyurethane-based hot-melt adhesives resulting from the polyaddition of a polyisocyanate, of a polyol and of a copolymer of ethylene, of vinyl acetate and of an ethylenically unsaturated monomer containing at least one primary hydroxyl group per mole. It also relates to a process for the preparation of the said adhesives. It also relates to the use of the adhesives for the adhesive bonding of flexible materials such as films.
