The invention relates to a curable composition comprising: a) at least one polymer having at least one silicon-containing group of formula &#x2014;Si(R)(Y)as defined herein; b) at least one titanium compound of formula Ti(L)(NX)or Ti(R)(L), where each X is independently a hydrogen atom, a hydrocarbon radical containing 1 to 20 C atoms, which may optionally contain one or more heteroatoms, in particular nitrogen atoms, or a silicon-containing organic group, or two X together with the nitrogen atom to which they are bound form a heterocyclic ring; each L is independently a hydrolyzable oxygen- or nitrogen-containing organic group, in particular an alkoxy group; Ris a hydrocarbon radical containing 1 to 20 C atoms, which may optionally contain one or more heteroatoms, in particular silicon atoms; and m is 1, 2, 3, or 4 and and n is 0, 1, 2, or 3, where m+n=4; and c) optionally at least one compound which has a hydrolyzable silicon-containing group and a molecular weight in the range of 100 to 1000 g/mol, preparations containing these compositions and use thereof.

Titanium complexes as vulcanization catalysts

Curable compositions are disclosed, containing at least one organopolysiloxane, which contains at least one hydroxyl group and/or group which can be hydrolyzed, in aqueous dispersion, i) at least one oganopolysiloxane having a dynamic viscosity of 0.05 to 7 (measured according to Brookfield DV-II+, spindle 3, 23&#xb0; C.), which is free of hydroxyl groups and/or groups which can be hydrolyzed, in aqueous dispersion, at least one cross-linking agent, at least one emulsifier, at least one cross-linking catalyst, at least one aqueous silicon-free polymer dispersion, at least one filler, and optionally water. The compositions are suitable as sealants, adhesives, or coating agents for application in the construction field, in particular in the sanitary field and in the kitchen field. They are characterized in relation to aqueous silicone preparations known up to this point by an improved adhesion spectrum, in particular on plastic substrates.

Curable compositions containing aqueous dispersions of organopolysiloxanes

The present invention relates to a composition, and a method of preparing and using the same. The composition contains at least one water-soluble or water-dispersible polymer or combinations thereof, and one or more filler particles that includes WDP gypsum particles. The WDP gypsum particles are obtained from waste gas-desulphurization plants and have a particles size distribution mean diameter ranging from 13 &#x3bc;m to 500 &#x3bc;m. The composition is particularly useful as a surface coating, a surfacing compound, a sealing compound, an adhesive or a molding composition.

Preparation containing gypsum from flue gas desulphurisation, method for using the same and use thereof

This invention relates to a jointing compound of an acrylate/acrylonitrile copolymer containing 2 to 8 carbon atoms in the alcohol component as binder and fatty compounds as plasticizer and also fillers and auxiliaries. Epoxystearic acid methyl ester in particular may be used as the fatty compound while a butyl acrylate/acrylonitrile copolymer in particular may be used as the acrylate/acrylonitrile copolymer. The combination of the two substances results in jointing compounds characterized by a dramatic improvement in elasticity (resilience). Accordingly, they are particularly suitable for substrates with different coefficients of thermal expansion.

Polyacrylate joint sealants

The invention relates to polystyrene binders modified by fatty compounds. The fatty compounds used are, in particular, esters of fatty acids or fatty alcohols, more especially triglycerides of higher fatty acids, preferably natural fats and oils. They may be added to the binder in high concentrations without adversely affecting the properties of the binder. However, their addition is of advantage in regard to the wetting properties, resistance to water and, above all, hardness. Dispersion adhesives, hotmelt adhesives and sealing compounds in particular can be improved with the binders according to the invention.

Polystyrene binders

Joint-sealing and coating compounds containing aqueous dispersions of polymers and copolymers, except for polyacrylates and acrylate copolymers, plasticizers and typical additives, such as pigments and the like, show excellent properties, particularly in regard to spreadability, smoothing behavior and resistance to spray water of uncured surfaces of these compounds providing they contain nonionic cellulose ethers selected from the group consisting of hydroxyethyl, hydorxyethyl-methyl, hydroxypropyl-methyl and hydroxypropyl cellulose having a Brookfield viscosity (2% aqueous solution at 20.degree. C.) of at least 3,000 mPa.s.
