for the best clarity, this is prepared by dissolving the resin and oleic acid in a mixture of the Methyl "Cellosolve" and part of the alcohol, and then stirring the "Zein G200" into this solution until dissolved. When solution is complete it is diluted with the remaining alcohol. The amount of dilution alcohol may be varied to obtain the solids concentration desired. The Methyl "Cellosolve" may be substituted by alcohol if faster drying is desired. |
