Cellulose Acetate/ Butyrate/ Ethyl Acetate/ Citronellal Varnish

Cellulose acetate/ butyrate is a mixed ester known as a plastic material.  I am able to dissolve the mixed ester in ethyl acetate/ citronellal ( 95:5 by volume) with warming. Cooling to 20 deg C yields a colorless, translucent viscous liquid which can be applied to a dried paint surface as a water-resistant varnish.
Drying time is being studied .

The solution can also be converted into a stable water:oil. emulsified paint formulation  as  vehicle/ binder with pigments.

Ethyl acetate is used primarily as a solvent and diluent, being favored because of its low cost, low toxicity, and agreeable odor. For example, it is commonly used to clean circuit boards and in some nail varnish removers (acetone and acetonitrile are also used). Coffee beans and tea leaves are decaffeinated with this solvent.[7] It is also used in paints as an activator or hardener.[citation needed] Ethyl acetate is present in confectionery, perfumes, and fruits. In perfumes, it evaporates quickly, leaving only the scent of the perfume on the skin.- Wikipedia
