* These materials are not in themselves solvents of nitrocellulose but are excellent cosolvents when mixed with 

 ethanol. A 50-50 mixture of the solvent with ethanol is usually employed. 



S 40 Recommended Mixtures 



The majority of the mixtures given below were designed to produce materials having 

 properties not available in solvents which could have been secured in the days when the
