Patent GB-485857-A (GB)
Title: Manufacture of paint removers
IPC: C09D9/00
Filed: 1936-11-20
Abstract: In the manufacture of paint removers containing methylene chloride, one or more other organic solvents, and film-forming thickening agents, a filling agent in the form of scales or leaves is added, to form a skin.  Specified scaly filling agents are mica, talc, fish scales, bismuth oxychloride, and graphite. According to examples, paint removers contain: (1) methylene chloride, methanol, methyl acetate, scrap celluloid and tale; (2) methylene chloride, methanol, methyl acetate, methyl cellulose and talc; (3) methylene chloride, methanol, methyl acetate, polyvinylmethyl ether and talc; (4) methylene chloride, alcohol, ethyl acetate, polyvinyl acetate and mica; (5) methylene chloride, methyl acetate, toluene, cr<\>zepe caoutchouc and talc; (6) methylene chloride, ethylene glycol-formal, methyl acetate, a condensation product of polyvinyl alcohol and formaldehyde, and talc; (7) methylene chloride, methyl acetate, ethyl alcohol, a condensation product of polyvinyl alcohol and acetaldehyde, and mica; (8) methylene chloride, xylene, acetone, polyvinylmethyl ketone and talc; (9) methylene chloride, xylene, polystyrene and talc; (10) methylene chloride, xylene, ethyl acetate, a mixed polymerization product of equal parts of vinyl chloride and vinyl acetate, and talc; (11) methylene chloride, xylene, ethyl acetate, aluminium naphthenate, and mica; (12) methylene chloride, acetone, acetyl cellulose, and talc; (13) a mixture of methylene chloride, nitrocellulose, acetone and methanol, emulsified with methyl cellulose or the sodium salt of cellulose glycollic acid in water, and mica; (14) an emulsion of polymerized vinyl acetate in water, mixed with methylene chloride, methyl acetate, methanol, xylene and talc.ALSO:In the manufacture of paint removers containing methylene chloride, one or more other organic solvents, and film-forming thickening agents, a filling agent in the form of scales or leaves is added, to form a skin.
