Abrégé
(EN) A two-component solvent-free polyurethane laminating adhesive for flexible packaging, including a First Component and a Second Component is provided. The First Component, which acts as a resin, includes a first vegetable oil based Polyol A in an amount from 20 to 40 weight percent, a second vegetable oil based Polyol B in an amount from 0.5 to 5 weight percent, and a Polyisocyanate C in an amount from 60 to 74 weight percent. The Second Component, which acts as a hardener, includes a first vegetable oil based Polyol A in an amount from 87 to 99 weight percent, and a Polyol E in an amount from 0.5 to 5 weight percent. The first vegetable oil based Polyol A is preferably a hydroxylated castor oil, and the second vegetable oil based Polyol B is preferably hydroxylated linseed oil.
