Abstract
The present invention relates to a silylated polyurethane obtainable by a process comprising the step of contacting at least one isocyanate with at least one isocyanate-reactive compound and with at least one aminosilane; wherein said at least one isocyanate comprises 2,4′-methylene diphenyl diisocyanate, and wherein said at least one isocyanate comprises less than 50.0% by weight of said 2,4′-methylene diphenyl diisocyanate based on the total weight of said at least one isocyanate. The present invention also relates to a process for preparing said silylated polyurethane. The present invention also relates to formulations and compositions comprising said silylated polyurethane, and the use thereof for the preparation of adhesives, coatings, sealants, elastomers, or foams.
