AQUEOUS COATING FOR PROTECTING SPRAY CABINS FROM ENAMEL OVERSPRAY AND PROCESS FOR PRODUCING IT

摘要

Aqueous and storage-stable compositions for the deposition of temporary barrier layers on spray-coating booths and the like contain - 5 to 80 % by weight of one or more C8-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, and - 1 to 15 % by weight of one or more layered silicate and/or polyacrylate and/or carbcoymethylcellulose, 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.
