Abstract: Aqueous and storage-stable compositions for the deposition of temporary barrier layers on spray-coating booths and the like contain5 to 80% by weight of one or more C.sub.8 -carboxylic acid and/or an alkali metal salt thereof,1 to 40% by weight of a pH-regulator consisting of one or more alkanol amine and/or alkali metal hydroxide, and1 to 15% by weight of one or more layered silicate and/or polyacrylate and/or carboxymethylcellulose,together with water and any further desired additives, and have a pH value of 6 to 10 and a viscosity of 30 to 50 DIN-sec.The invention also provides a process for the production of such compositions.

Abstract: The invention relates to coagulating agents formulated in the form of two separate components A and B for coagulating paints, waxes and coating compositions, which agents contain one or more aluminosilicate(s), one or more wax(es) and/or wax analogues and one or more active ingredient(s) and/or auxiliary material(s) that are known per se for coagulating and/or formulating, as well as to the aqueous slurries of the two-component agents and to the use thereof in circulation waters of paint disposal units.

Abstract: A time-delayed hardener composition for aqueous alkali metal silicate solutions, the total formulation, and its application for soil stabilization, in which the hardener composition consists essentially 20 to 60% by weight of dimethyl carbonate and the balance to 100% by weight of diethyl carbonate.

Abstract: Aqueous alkali metal silicate bonding compositions having a molar ratio of SiO.sub.2 :Me.sub.2 O of 2.4:1 to 3.4:1, wherein Me is sodium and/or potassium, a solids content of about 35 to 50 percent by weight, and containing triethanolamine. The bonding compositions can be mixed with fillers such as quartz sand and used for the manufacture of molded forms for the casting of metals.
