A process is provided for making a moisture-curable silylated resin composition by reacting (i) at least one polyol, (ii) at least one polyisocyanate and (iii) at least one isocyanatosilane, optionally in the presence of catalyst, wherein the NCO/OH ratio is less than 1. The resulting moisture-curable silylated resin composition is useful in the manufacturer of each product as moisture-curable sealants, coatings and adhesives.
L~invention concerne un procédé de fabrication d~une composition de résine silylée durcissable par l~humidité, ledit procédé consistant à mettre en réaction (i) au moins un polyol, (ii) au moins un polyisocyanate et (iii) au moins un isocyanatosilane, éventuellement en présence d~un catalyseur, le rapport NCO/OH étant inférieur à 1. La composition de résine silylée durcissable par l~humidité résultante est utile pour la fabrication de produits durcissables par l~humidité, tels que des produits d~étanchéité, des revêtements et des adhésifs.
