Abstract: Silylated polyurethanes can be manufactured by reacting at least one polyol compound, having a molecular weight from 4000 to 20,000 dalton, with a diisocyanate, with a stoichiometric excess of the diisocyanate compound with respect to the polyol compound or compounds, with the result that a polyurethane prepolymer that is isocyanate-terminated is formed; and by subsequently reacting the polyurethane prepolymer with one or more OH-terminated silanes of formula (1) to yield a polyurethane having predominantly terminal alkoxysilyl groups. In formula (1), m is equal to 0, 1, or 2, R1 is an alkyl residue having 1 to 4 carbon atoms, R2 is an alkyl residue having 1 to 4 carbon atoms, R3 is a divalent organic residue having 1 to 12 atoms, selected from C, N, S, and/or O, in the chain, but by preference exclusively carbon atoms, R4 is a hydrogen atom or an alkyl residue having 1 to 10 carbon atoms, and R is a difunctional organic group, preferably a linear or branched alkyl group having 1 to 6 carbon atoms.

Abstract: The invention relates to a one-component, moisture-curing adhesive containing at least one polyoxyalkylene and/or poly(methyl)acrylate prepolymer having at least one hydrolyzable silane group, at least one filler, and auxiliary materials and additives, wherein the prepolymer has a molecular weight of 4,000 to 40,000 g/mol and the adhesive has a viscosity of 200 to 10,000 mPas.

Abstract: The present disclosure relates to silane-crosslinking adhesives or sealants comprising a) at least one polymer of the general formula (I) in which R is a monovalent to tetravalent hydrocarbon radical, R1 is an alkyl radical having 1 to 8 C atoms, R2 is an alkyl or alkoxy radical having 1 to 8 C atoms, and A is a carboxyl, carbamate, carbonate, ureido, urethane or sulfonate linker or an oxygen atom, x is 1 to 8, and n is 1 to 4, and b) at least one adhesion promoter, dryer and/or reactive diluent. The adhesion promoters, dryers, and/or reactive diluents are ethoxy-functional ?-silanes of the general formula (II) in which R3 is an organic radical attached to the methylene group via a heteroatom, and R4 is an alkyl radical having 1 to 8 C atoms or an ethoxy radical. The disclosure further relates to a process for producing the adhesives or sealants, and also to their use.
