Perfect reproductions thanks to reliable solutions



Thanks to outstanding resistance to chemicals and heat SILASTOSIL® M line two-component, room-temperature-vulcanizing RTV-2 silicone rubbers are ideal for making molds for low melting alloys. They are used to cast into these molds to make exact reproductions, specially for casting pewter, metallic & glitter effects products, and in the lost wax process for bronze casting. They are easy to operate and offer many other advantages:


excellent flowability

- easy to mix and to operate

- highly transparent

- adjustable working, operation and curing times

- easy de-molding

- excellent non-stick effect

- very good resistance to most chemicals

- very good resistance to agressive components of some types of resins

- high degree of precision in reproduction

- very low shrinkage (≤0.1-0.2%)

- very good resistance to high temperatures and ageing

- excellent tear and tensile strenghts

- excellent elongation

- high resistance to wearing and shearing

- cost-effective



TERRAFLUID® line silicone fluids are ideal to adjust the hardness of the silicone molds, and also to minimize the material costs. TERRASIL® AUX line additives for silicone rubbers are used to accelerate the curing process, and also to improve the mechanical properties of the silicone molds.
