PMC™-744 has been used for years by mold-making professionals to cast plaster, concrete, resins, etc. It is excellent for making moulds that are strong, durable and dimensionally stable. Low viscosity ensures fine detail reproduction.
PMC™-744 is ideal for making ceramic case moulds and plaster block moulds, reproducing ornamental plaster, making moulds for casting concrete, casting a variety of Smooth-On urethane resins, casting wax for making candles and making mechanical rubber parts.
PMC®-770 is a shore 70 A addition to our line of industrial liquid rubber products (such as PMC®-780 and PMC®-790) used for a variety of industrial and casting applications. mixed two parts a to one part b by weight, PMC®-770 pours easily and cures at room temperature to a solid shore 70 A rubber that has exceptional performance characteristics and dimensional stability. It is suitable for production casting of abrasive materials such as concrete (pre-cast concrete, making concrete stamping pad etc) and gypsum plasters with high exotherms. It is also suitable for rubber mechanical parts of varying configurations (gaskets, wheels and pullies) as well as ball mill liners and vibration/shock pads.Pot life 30 min – Demould 16hrs
