Abstract: Aqueous redispersible powders which contain a water-soluble polymer and at least one organic silicon compound, in which at least 50 percent by weight of the organic silicon compound(s) used to prepare these powders are liquid or solid at room temperature at 1,020 hPa (abs.), have a boiling point of at least 150.degree. C. at 1,020 hPa (abs.), and contain an average of not more than 1.8 SiC-bonded organic radicals per silicon atom, and have at least one hydrogen atom bonded directly to silicon per molecule, or at least one hydroxy group bonded to silicon per molecule, or at least one hydrocarbon radical bonded to silicon via oxygen per molecule which may be substituted by an alkoxy group, or a mixture of at least two such condensable substituents in which the organic silicon compound(s) are used in an amount of at least 30 percent by weight, based on the total weight of the powder (calculated as anhydrous powder).

Abstract: A halogen-free flameproofed thermoplastic molding material consists of a halogen-free thermoplastic resin (A) and one or more further halogen-free components.The thermoplastic resin (A) is present in an amount of from 30 to 90% by weight, based on the molding material. The latter contains, as further components, from 1 to 50% by weight of a phenol/aldehyde resin (B), from 1 to 50% by weight of a nitrogen-containing organic compound (C) and from 3 to 50% by weight of a phosphorus-containing organic compound (D), the percentages in each case being based on the molding material.The molding material is used for the production of flameproofed moldings.

Abstract: A stencil printing ink is described, comprising 0.5 to 20% by weight pigment, 5 to 30% by weight extender pigment, 0.5 to 5% by weight water-soluble polymer (the viscosity of its 10% aqueous solution is at least 40 cps), 3 to 15% by weight (calculated as solids) o/w type resin emulsion, 5 to 20% by weight polyhydric alcohol and water. This ink can produce printed images without being affected by printing conditions such as temperature and application pressure. Thus, it is suitably used in stencil printing for non-professional or unskilled people.

Abstract: This invention relates to aqueous adhesive solutions. More particularly, this invention relates to an aqueous adhesive composition for mechanical labeling based upon starch derivatives and having a content of flow-regulating additives and, optionally, other customary additives, which comprises:(a) at least one hydroxyalkyl ether of oxidized starch with a mean degree of substitution (MS) of .ltoreq.0.2, together with(b) at least one polymer dissolved in the aqueous phase, the polymer being selected from the group consisting of water-soluble cellulose derivatives, water-soluble synthetic polymers, casein, and water-soluble starch derivatives different from component (a).

Abstract: A composition comprising mineral wool and polyolefin fibers is adaptable for spraying onto a ceiling or wall or the like to form a textured acoustical coating.The fibers are mixed with a binder, water and foaming agent to form a foamy composition. The composition is confined under pressure and released through a nozzle to form a steam. Compressed gas is introduced into the stream to atomize the composition.

Abstract: The production rate and yield resulting from the dewatering of starch conversion products containing swollen starch granules resulting from treatments with cationic reagents is improved by the addition to the starch slurry of a water soluble anionic polymer.

Abstract: A cold-setting starch adhesive comprising the mixture of three different types of corn starch having widely different properties, i.e., high amylose corn starch having an amylose content of at least 50%, ordinary corn starch and waxy corn starch, in specific proportions. The adhesive shows excellent properties due to the effective combination of the outstanding properties of the individual types of starch.

Abstract: An ammonium salt of the reaction product, in an aqueous medium, of a hydrolyzed styrene-maleic anhydride copolymer and a dispersed hydroxy-alkyl modified starch, is used as a component of a binder composition for coating materials. Film-forming coating compositions comprise, as a binder, said reaction product and an elastomeric or resin latex, and further comprise a paper coating pigment, and barium carbonate and ammonium bicarbonate as scavenging agents. Additionally, said compositions may comprise up to about 25%, by weight of the binder, of ammonium zirconyl carbonate.
