Fast-demold firm-durometer platinum-cure RTV-2 mold making silicone

General Information

P-614 is a fast curing, two-component addition cure silicone rubber mold making material that has a minimum working time of 40 minutes, yet can be demolded in only 3 to 4 hours. This allows the mold maker to produce both sides of a two part mold in one 8 hour shift. Parts can also be produced in the same day from a one piece mold. P-614 also has a high durometer, minimal shrinkage and excellent chemical resistance, making it a superior choice for prototyping and casting solid polyurethane resins.
