This formula replaces ethyl ether with acetone as it's solvent. It will take a little longer to dry, but once it is cured the resin is the same as collodion. Used to attach electrodes to the skin or scalp. Primarily, but not limited, for EEG monitoring (Epilepsy, Sleep Disorders, Ambulatory...). Especially useful when it is important to maintain a secure contact for monitoring. When applied correctly, collodion will hold even when the skin is hairy, perspiring, or oily.
