Casting rubber for smelting low melting alloys. Resistant up to 350° C. Suitable for moulds designed for metal fusion, for example, lead, tin and low melting alloys. It is possible to continuously work with this rubber and to repeatedly produce the model both using free and centrifugal casting without deforming the mould, thanks to the lasting toughness of the cure and the ability to dissipate heat.
Cod. GS-736
