Characteristics of GOHSENOL

Gas Impermeability
GOHSENOL films formed either independently or on substrates like paper, show very high impermeability to many kinds of gases such as oxygen, nitrogen, hydrogen, carbon dioxide, and helium, but exceptionally, allow moisture and ammonia to permeate through.
