Abstract:
1. A composition comprising at least one isocyanate sub-composition, having at most 5% by weight of diisocyanate monomers, at least one dehydrating agent of formula wherein Z is a hydrocarbyl, a silanoxanyl or a silazanyl group, Hc and Hc′ independently are a hydrocarbyl group having at most 15 carbon atoms, v is 0 or 1, and Y is i) an amino group, optionally having a substituent selected from the group consisting of a residue of an oxygen acid after elimination of a hydroxyl group, a hydrocarbyl group, a trihydrocarbylsilyl group, and a group of formula wherein Hc or ii) a selenium, sulfur or oxygen atom, having a substituent being a residue of an oxygen acid after elimination of a hydroxyl group, and at least one non-alkylatable organic or inorganic base, being an at least partially aromatic tertiary amine or tertiary phosphine, in an amount corresponding to at least 0.1 times the amount of dihydrocarbylsilylene, when expressed as silicon atom equivalents.
