Title: Improvements in and relating to coating and plastic compositions containing cellulose ethers
IPC: C08L1/26
Filed: 1930-06-12
Abstract: Water-resistant coating-compositions are produced by incorporating with a cellulose ether a non-solvent softener with or without the addition of a solvent softener compatible therewith.  For the non-solvent softener, a high boiling viscous product such as liquid petroleum or petroleum jelly may be used, whereas for the solvent softener, the following are specified: dibutyl phthalate, benzophenone, a mixed glyceryl ester of acetic acid and lauric acid, a mixed glyceryl ester of acetic acid and the acids of coco nut oil, and mixed glyceryl esters of acetic acid with palmitic or myristic acids.  An addition may also be made of a volatile solvent such as benzene, xylene, gasolene, organic chlorine compounds, esters such as ethyl acetate, or ethyl alcohol.  The ratio of non-solvent softener to solvent softener is greater than 50 : 50 and is preferably 80 : 20, whilst the amount of composite softener employed is between 0,4 and 4 parts to each 10 parts of cellulose ether.  Natural or synthetic resins such as congo, rosin, rosin ester, kauri, and the like may be added in amounts up to 100 per cent or more on the weight of the cellulose ether, as well as other ingredients such as pigments, oils, driers, and thinners.ALSO:Water-resistant compositions are produced by incorporating with a cellulose ether, a non-solvent softener with or without the addition of a solvent softener compatible therewith.
