Hi-Ro Slip is a silicone mold additive specially developed by P.T.M. to create self-releasing molds. Transfers can be stubborn when trying to release them from a silicone mold and usually require applying a release agent to the mold beforehand. Hi-Ro Slip is only needed once during the creation of your mold, eliminating constant use of release agents and unneeded steps, thereby creating a more efficient process and allowing you to run better quality prosthetic transfers
