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.
