Abstract

272,197. Guillemin, J. J. J. June 2. 1926, [Convention date]. Waterproofing; proofing-compositions.-A composition for waterproofing leather and protecting it from wear comprises a mixture of 20 parts of gum or resin, 45 parts of gum-dissolving oil, 34 parts of spirit, and 1 part of litharge. The resin may be vegetable resin such as sandarac, mastic, dammar, colophany, elemi and benzoin; fossil resin; or artificial resin prepared by heating phenol or naphthalene with formaldehyde in presence of an acid or alkali. The resin is heated to a temperature between 150 and 300‹ C., and the oil to a temperature of 130-150‹ C., and a mixture of 45 parts of oil and 20 parts of resin made. The temperature is lowered to 70-80‹ C., and a mixture of one part of litharge in 34 parts of spirit of turpentine stirred in. White spirit may be used in place of turpentine, and the oil may be linseed oil, poppy oil, castor oil, or China wood oil.
