Ideal for prototype design and production tooling



SILASTOSIL® M line two-component, room-temperature-vulcanizing RTV-2 silicone rubbers are ideal for prototype design and production tooling, especially for rapid prototyping. The process begins with an original SLA model being extracted from SILASTOSIL® M line silicone rubber which is a high-tear, platinum-catalyzed silicone used by professional prototype designers, because it offers the advantage of letting you see your model as you are cutting the rubber and minimizing damage to the model.


SILASTOSIL® M line moldmaking RTV-2 silicone rubbers are easy to use 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 used to adjust the hardness of the silicone rubbers and also to reduce the material cost. TERRASIL® MRA line mold release agents are designed to make de-molding easier.
