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

Isocyanate prepolymers having an NCO content of 1.5 to 5.0 wt. % and a monomeric diisocyanate content of less than 0.5 wt. % which are the reaction products of

Isocyanate prepolymers, a process for their preparation and their use

Two-component polyurethane coating compositions essentially containing A) a polyisocyanate component containing A1) certain aliphatic polyisocyanates and A2) certain aromatic polyisocyanates, B) a polyol component containing B1) selected polycaprolactone polyols and/or selected polyether polyols, and optionally B2) other organic polyhydroxyl compounds, and C) known additives used in surface coating technology; and the application of such coating compositions for the manufacture of floor sealers or thin coatings.
