Title: ADHESIVE DUAL-COMPONENT COMPOSITION BASED ON POLYURETHANE
Abstract:
The invention relates to an adhesive dual-component composition based on polyurethane, comprising an -NCO component and an -OH component such that: the -NCO component is a composition comprising A) at least one polyurethane prepolymer comprising at least two NCO terminal groups obtained by polyaddition reaction of at least one aliphatic polyisocyanate selected from aliphatic diisocyanate monomers and mixtures of at least one aliphatic diisocyanate monomer with at least one triisocyanate based on XDI, and at least one polyester diol, and B) at least one triisocyanate based on XDI; and the -OH component is a composition comprising at least one polyester polyol. The invention relates to a method for producing a multilayer structure implementing an adhesive composition according to the invention, as well as to the use of such a structure in the field of flexible packaging.
