This invention relates to polyurethane compositions which cross-link via a silane polycondensation and contain at least one alkoxysilane-functional polyurethane, at least one basic filler, at least one reaction product of an aminosilane with a maleic or fumaric ester, at least one organometallic compound and optionally additional auxiliary substances, to a process for their preparation, and to their use.

Condensation cross-linking polyurethane materials containing special aminosilanes, a method for the production thereof and their use

The invention relates to polyurethane materials, cross-linked by silane polycondensation, containing alkoxylsilane functional polyurethanes, alkaline fillers, phosphorous compounds aminosilanes, organometallic compounds and optionally additional auxiliary agents, to a method for their production and to the use thereof.

Phosphate-stabilized polyurethane materials, cross-linked by condensation, method for their production and use thereof

The present invention relates to new alkoxysilane-functional piperazinone derivatives, a process for their production, as well as their use as additives in sealants, adhesives, lacquers or coating agents.

Piperazinone derivatives with alkoxysilane groups

This invention relates to polyurethane prepolymers which comprise alkoxysilane terminal groups and which are based on special, very high molecular weight polyurethane prepolymers, to a method of producing them and to their use as binders for low-modulus sealing materials.
