The invention relates to two-component polyurethane bonding agents based on a polyester polyol comprising an aliphatic or cycloaliphatic polyisocyanate and a hardening component based on a polyamine mixture, suitable for use as UV resistant flocking adhesives for the flocking of polymer substrates. Said adhesives can be incorporated into all known processing methods and enable flocked articles with a higher UV-resistance and good abrasion resistance to be produced.
L'invention concerne des liants polyuréthane à deux composants réalisés à base d'un polyesterpolyol comportant un polyisocyanate aliphatique ou cycloaliphatique, et d'un composant de durcissage à base de mélanges de polyamines, lesdits liants servant d'adhésifs de flocage résistants aux UV pour le flocage de substrats polymères. Lesdits adhésifs peuvent être traités selon tous les procédés de traitement connus et permettent de réaliser des articles floqués ayant une résistance élevée aux UV et à l'usure.
