Silcoflex-HE is a highly tear-resistant RTV silicone impression material (RTV: cross-linking at room temperature). It is particularly suitable for moulding complicated figures with extreme undercuts and is also heat-resistant like Silcotin-HB. It is used in mould making wherever, instead of a two-part or multi-part mould, a one-part elastic, tear-resistant mould makes casting easier and increases cost-effectiveness. As Silcoflex-HE is more expensive than Silcotin-HB, the two products are often mixed together to create a flexible, elastic mould that meets the requirements. The mixing ratio can be varied, it depends on how flexible the mould is to become. All common casting compounds can be used for casting the mould, e.g. relief and picture wax, casting ceramics, polyester resins, polyurethane casting compounds, plaster, concrete, casting soap and of course also tin. Silcoflex-He has a medium viscosity and therefore excellent flow properties. It is almost shrinkage-free (5%) and self-venting. It is mixed with 1.5 - 2% silicone cross-linker and cures within 90 - 300 minutes. Delivery includes detailed instructions, crosslinker (10 ml) and mixing bowl. Total weight 500 g
