NC with a nitrogen content of 11.8% to 12.3% has the designation E, as this nitrolose is soluble in Esters (the A and AM-grades are also soluble in esters). E-grades are the standard grades for wood and leather coatings. In comparison to the A-grades they are more resistant to alcohol. Its properties are: 1- Form hard films 2- very fast solvent evaporation 3- Easy to dilute with alcohols, alitic and aromatic hydrocarbons. 4- Attain very good mechanical properties (cold-check, elongation, hardness, tear resistance)
