Best for making molds of 2-dimensional flat pieces for architectural or decorative objects. Molds are suitable for casting plaster, concrete and wax. NOTE: Latex can be used for limited casting of some resins. The higher the exotherm of the casting material, the quicker the mold will degrade and become unusable. Smooth-On silicone rubbers are better suited for resin casting applications.
