To prepare a 5% binder solution of cellulose acetate, you’ll need cellulose acetate, a solvent like acetone or methyl acetate, a scale, and a mixing container.
Start by measuring out 100 mL of your chosen solvent. For a 5% solution, weigh out 5 grams of cellulose acetate. Gradually add the cellulose acetate to the solvent while stirring continuously. It’s important to keep stirring until the cellulose acetate is fully dissolved, which may take some time. If you’re using acetone, cooling the mixture slightly can help with solubility.
Once the cellulose acetate has completely dissolved, the solution should be clear and free of undissolved particles. Finally, store the binder solution in a sealed container to prevent any evaporation of the solvent.
