PMC-744
Product Code:SOR7445G
Used for years by mold making professionals to cast plaster, concrete, resins, etc... Excellent for making molds that are strong, durable and dimensionally stable. Low viscosity ensures fine detail reproduction. Ideal for making ceramic case molds and plaster block molds, reproducing ornamental plaster, making molds for casting concrete, casting a variety of Smooth-On urethane resins, casting wax for making candles and making a mechanical rubber parts.
To prevent adhesion between the rubber and model surface, models made of porous materials (gypsum plasters, concrete, wood, stone, etc...), must be sealed (SuperSeal or One Step) prior to applying a release agent. A high quality shellac is suitable for sealing modeling clays that contain sulfur or moisture (water based) or thermoplastics (polystyrene). A release agent (Universal Mold Release) is necessary to facilitate demolding when casting into or over most surfaces. In & Out II is recommended for releasing abrasive materials like concrete.
