Abstract
The invention relates to a moisture-crosslinkable hot-melt adhesive which is composed of a polyurethane prepolymer obtained by polyaddition of at least one polyol to at least one isocyanate chosen from the group of diisocyanates trimerized as isocyanurates and reaction products of diisocyanates with water, the prepolymer having a content of free NCO group of between 1 and 25% by weight. The adhesive according to the invention may be used for the adhesive bonding of fixing components of the Velcro® type to articles intended for hygiene.
