Ethyl Acetate (C4H8O2, CAS 141-78-6) is a clear, highly flammable ester solvent with a sweet, fruity odor, a specific gravity of about 0.90, a boiling point of 171°F (77°C) and a flash point near 24°F (-4°C). It is one of the most widely used solvents for coatings, flexible packaging inks, adhesives, nail polish remover, pharmaceutical extraction and decaffeination. Ethyl acetate tanks need grounding, vapor control and fire protection. Typical recommendation: HDPE tank, PP fittings, EPDM gaskets. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
HDPE is the most economical tank material for Ethyl Acetate, rated Excellent. Polypropylene and nylon are also rated Good or better. Avoid PVDF (Kynar®) tanks; PVC, CPVC and PVDF fittings; Buna-N and Viton® gaskets.
