ZEORORA®H

Ozone depletion and global warming have been discussed worldwide, with a growing need to protect the environment globally. As a result, virtually all production of CFC substitutes (HCFCs), which are used instead of controlled CFCs, is scheduled to be discontinued in 2020 because HCFCs also have ozone depletion potentials although they are low. ZEORORA®H is a fluorinated solvent (c-HFC) with no ozone depletion potential. It is a non-combustible solvent which has very small environmental impact.
