Let's make a great impression ClearRetain's impression putty is a vinyl polysiloxane impression material with a very high viscosity that provides excellent dimensional accuracy and stability. The impression putty consists of two pastes, which when mixed together harden to form a base for taking a dental impression. It is designed for use as the tray material for the reproduction of teeth shaping. Our impression putty has a two-year shelf life. The impression putty ingredient list is polydimethylsiloxane polymer, silicon dioxide, polymethyl hydrogen siloxane, and plasticizer pigments.
