Abstract
The use of alkoxylated alkyl alcohols having 8 to 18 carbon atoms in the alkyl radical and with a total of 2 to 12 ethylene oxide and/or propylene oxide units per molecule as additive for paint stripper based on organic solvents, the paint stripper containing less than 5 wt. % of water; corresponding paint strippers based on alcoholic organic solvents; paint stripping process using these agents, particularly for non-ferrous metals.
Claims13
Paint stripper based on organic solvents which contains less than 5 wt. % of water and a total of 60 wt. % to 98 wt. % of alcoholic organic solvent and
- c) a total of 1 wt. % to 20 wt. % of one or more alkoxylated alkyl alcohols having 8 to 18 carbon atoms in the alkyl radical and with a total of 2 to 12 ethylene oxide and/or propylene oxide units per molecule,
- d) 1 wt. % to 10 wt. % of alkalizing agent selected from alkali metal hydroxides and alkanolamines, and if desired
- e) 0.1 wt. % to 20 wt. % of further additives, the quantity proportions of the constituents adding up to 100 wt. %.
