P525 PlatSil Silicone

P-525 is a platinum-cured, room temperature curing (RTV), silicone rubber designed for the manufacture of high-performing, flexible molds. This two-part (Catalyst & Base), liquid silicone rubber has a Shore Hardness of A25, a pour time of ~15 minutes, and a demold time of ~4 hours. P-525 molds are commonly used to cast the following materials: Urethane (polyurethane) plastic and rubber Plaster Polyester Casting Resin Cement, Concrete Epoxy Soap Wax Low-Melt Metals   Release agent is not necessary for casting most materials into P-500 Series molds, but for longer mold life with epoxy, polyurethane or polyester resins, a barrier coat or release agent (SupraLease PTR) is recommended. This is a pourable rubber, but it can be easily thickened with silicone thickener for brush-on application.
