From WikiDent
ED Primer is an acidic solution (pH 3) containing a phosphate monomer (10-MDP), HEMA, a salicylic acid derivative (5-NMSA) and a polymerization activator agent.

Mechanism of Action
ED Primer is a self-etching primer. When applied to tooth surface, the primer dissolves the smear layer and penetrates the enamel microstructure or dentinal tubules. As ED Primer dissolves the tooth surface the acidity increases. Decalcification stops when ED Primer is finally neutralized by calcium ions. When the chemically activated cement contacts ED Primer, the polymerization activator initiates polymerization of the cement.
