摘要:
The description concerns quick-acting joint sealing compounds containing: aqueous polymer dispersions (I); non-ionic cellulose ethers (II) from the group made up of hydroxy ethyl, hydroxy ethyl methyl, hydroxy propyl methyl and hydroxy propyl celluloses; fillers; and, where appropriate, customary additives like pigments, plasticisers, extenders, coagulants, defoamers, dispersing agents, pH regulators and conserving agents and ageing protectors; which can be manufactured by the intimate mixing of (I) with the other components. In order to be able to introduce (II) in quantities lying above the solubility limit, the feature of the joint sealing compounds is that (II) is added in retarded form mixed with the fillers and mixed in.

摘要:
Wax compositions are provided with improved properties for various applications, such as coating of composite cellulosic materials, e.g., composite wood material, particleboard, medium density fiberboard, construction board or combination thereof. As described herein, paraffin wax compositions are provided that have n- paraffin content of from about 30%wt to about 95%wt, and a 95% carbon number spread of from about 1 carbon atoms to about 23 carbon atoms, which provide enhanced water proofing properties as compared to waxes currently used.

In order to be able to introduce (II) in quantities lying above the solubility limit, the feature of the joint sealing compound is that (II) is formed into a slurry in retarded form in small quantities of water and added and mixed in after the slurry has been formed.
摘要:
Es wird eine Dichtmasse angegeben, die nass aufbringbar und zu einer elastischen Dichtung (1) aushärtbar ist. Die Dichtmasse enthält ein Matrixmaterial (11) und eine Vielzahl von Partikeln (12), die einen Äquivalentdurchmesser von 0,05 mm oder mehr und von 0,8 mm oder weniger haben. Weiter werden eine Verwendung der Dichtmasse, ein Gehäuse (20) - insbesondere für ein elektronisches Steuergerät - und ein Verfahren zur Herstellung des Gehäuses (20) angegeben.
摘要:
Disclosed is a fluorine-containing polymer prepared by polymerizing (I) a polyfluoroalkyl group-containing (meth)acrylate which is substituted at alpha-position, in the presence of (II) a blocked isocyanate compound. A water- and oil-repellent composition containing the fluorine-containing polymer can impart the excellent water- and oil-repellency, and excellent durability thereof to substrates.
摘要:
Joints sealants with early water resistance contain aqueous polymer dispersions (I); non-ionic cellulose ether (II) from the group formed by hydroxyethyl, hydroxyethylmethyl, hydroxypropylmethyl and hydroxypropylcellulose; if necessary usual additives such as fillers, pigments, plasticisers, extenders, thickeners, antifoaming agents, dispersing agents, pH regulators, preservatives and anti-ageing dopes, as well as at least one organic liquid component from the group of usual additives. These joint sealants can be produced by intimately mixing (I) with the remaining components. In order to be able to add (II) in amounts higher than the solubility limit, the joint sealants are characterized by the fact that (II) is added in suspension in retarded and/or non retarded form to the liquid organic components, then mixed in.
