| description | Prepolymer comprising the reaction product of: a) one or more polyisocyanates; and b) i) one or more copolymer polyols having a solid dispersed in a continuous phase or ii) a mixture of one or more copolymer polyols having a solid dispersed in a continuous phase or iii) one or more alkoxylated bisphenols; or iv) a mixture thereof; wherein the prepolymer has an isocyanate content of 2 to 5 percent by weight. Reactive hot melt adhesive comprising the prepolymer of the invention wherein the prepolymer has an application temperature of from 50 to 140 DEG C and a viscosity at the application temperature of from 3,000 to 50,000 centipoise. Method of bonding using the adhesive of the invention.
Cette invention concerne un prépolymère comprenant le produit de réaction de: a) un ou plusieurs polyisocyanates; et b) i) un ou plusieurs polyols de copolymère comportant un solide dispersé en phase continu ou ii) un mélange d'un ou de plusieurs polyols de copolymère polyols comportant un solide dispersé en phase continue ou iii) un ou plusieurs bisphénols alkoxylés; ou iv) un mélange de ces composés, le prépolymère ayant une teneur en isocyanate de 2 à 5 % en poids. Dans la composition adhésive thermofusible réactive, le prépolymère a une température d'application comprise entre 50 et 140 DEG C et une viscosité à la température d'application de 3,000 à 50,000 centipoise. Est également décrit un procédé de fixation au moyen de la composition adhésive selon l'invention. |
