摘要:
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 μm to 500 μm. The composition is particularly useful as a surface coating, a surfacing compound, a sealing compound, an adhesive or a molding composition.
摘要:
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.
摘要:
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.
摘要:
Joint-sealing materials and coating materials which contain aqueous dispersions of polyacrylates or acrylate copolymers, plasticizers and the usual additives, such as pigments and the like, have excellent properties particularly with regard to brushability, smoothing behavior and wash-out resistance when they contain a nonionic cellulose ether selected from the group consisting of hydroxyethyl cellulose, hydroxyethyl-methyl cellulose, hydroxypropyl-methyl cellulose and hydroxypropyl cellulose having a Brookfield viscosity in a 2% aqueous solution at 20.degree. C. of at least 3000 mPa.s.
摘要:
Early-rain-resistant joint-sealing compounds containing(a) aqueous polymer dispersions (I),(b) nonionic cellulose ethers (II) selected from the group consisting of hydroxyethyl, hydroxyethyl-methyl, hydroxypropyl-methyl and hydroxypropyl cellulose, and(c) optionally typical additives, such as fillers, pigments, plasticizers, extenders, thickeners, foam inhibitors, dispersion aids, pH regulators, preservatives and anti-aging agents,which can be produced by thorough mixing of (I) with the other constituents. To be able to introduce (II) in quantities above the solubility limit, the joint-sealing compounds are characterized in that (II) is suspended in retarded form in small quantities of water and is added and intermixed after suspension.

摘要:
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.

摘要:
The invention relates to a silane-crosslinking adhesive or sealant containing a polymer that is made up of an organic backbone that carries at least two alkoxy- and/or acyloxysilyl groups, and at least one N-silylalkylamide as an additive. The invention also relates to use of the N-silylalkylamide as an additive in silane-crosslinking adhesives or sealants.
