Elastosil M 4470 is a 60 duro RTV-2 silicone rubber. This condensation-curing silicone vulcanizes at room temperature with the addition of either of two catalysts.
Due to the excellent mechanical properties of the cured rubber as well as its high resistance to casting resin, ELASTOSIL® M4503 is especially suitable for reproducing models with pronounced undercuts in casting resins. Other materials, such as wax and plaster, may be cast without any problems in moulds made from M4503.
A high strength, condensation cure silicone with excellent flow and perfect for soft moulds. It has a shore hardness of approximately 12 ~ 14. Used widely in the special effects industry.
A multi-purpose condensation cured moulding rubber. Very good elongation, tear strength and tensile strength. Blue colour coded catalyst to ensure thourough mixing. Can be used with polyester, polyurethane and plaster casting.
