Curable alkoxysilyl-terminated polymers may be used for architectural coatings, particularly flat roofs, if specific HALS UV absorbants are included in the coating formulation.

Coating composition for sealing surfaces

The objectionable odor of one component condensation curable organopolysiloxane compositions is eliminated by replacing all or the most substantial part of water scavenger vinyltrimethoxysilane with a phenyltrialkoxysilane, without compromising storage or curing properties.

Cross-linkable masses based on organyloxysilane-terminated polymers

Weather resistant and water repellent surfacing compositions especially useful in roofing applications contain an alkoxysilane-terminated polymer and a reactive silane plasticizer containing a Chydrocarbon group. The surfacing compositions are of low viscosity and may be used without non-reactive plasticizers or organic solvents.

The invention provides curable adhesives of high tensile sheer strength, which contain an &#x3b1;-silane-terminated polyurethane prepolymer containing low molecular weight polyether or polyester groups in the polymer backbone, and a silane-terminated polyether polymer containing polyether groups of higher molecular weight.

Silane-crosslinking compositions

Physical properties and soiling resistance of polymer-bound inorganic composites such as artificial stone are improved by incorporating a silane adhesion promoter and at least one of three organosilicon compounds.

Production of a composite comprising inorganic material and organic polymer

Alkyl silanes are prepared by silylating an unsaturated hydrocarbon with an Si&#x2014;H functional silane employing an iridium chloride coordination compound as a catalyst and a polymeric polyene as a cocatalyst. Reaction bottoms can be worked up to provide an iridium-containing composition which remains catalytically active.

Iridium-catalyzed production method for organosilicon compounds

Isocyanate-free foamable mixtures suitable for filling construction voids and for other uses, comprise isocyanate-free, alkoxysilane-terminated prepolymers (A) which have a silane end group of the formula [1], where

Isocyanate-free expandable mixtures exhibiting a fast hardening rate

Unsaturated organosilicon compounds are prepared by the reaction of a halo-functional organosilicon compound with a salt of an unsaturated carboxylic acid in the presence of a tertiary phosphine.

Process for preparing unsaturated organosilicon compounds

Useful products are recovered from the bottoms of aminoalkylsilane production in high yield and purity by reaction with alcohol, increasing the economics of aminoalkylsilane synthesis.

Process for preparing aminoalkysilanes

Preparation of organosilanes by hydrosilylation of an alkene takes place in a continuous manner using an iridium hydrosilylation catalyst and diene cocatalyst. The continuous process provides high yields in a safe and economical manner.

Continuous production of organosilanes

Alkoxy-crosslinking one-component moisture curing compositions contain a polymer bearing (alkoxy)(methyl)silylalkyl-terminal groups, and specific silanes as described herein. The compositions exhibit improved shelf life and yet retain other desirable characteristics.

Alcoxy cross-linking, single-component, moisture-hardening materials

Surface-modified solids bearing groups of the formula ISiR&#x2014;R&#x2014;NH&#x2003;&#x2003;(I),are prepared by reacting a solid having OH groups on a surface thereof with a cyclic silazane of the general formula IIwhere
