Discription

XIAMETER RTV-3481 Moldmaking Rubber is a twocomponent material consisting of XIAMETER RTV-3481 Base which when mixed with a XIAMETER® RTV-3081 Curing Agent, cures at room temperature by a condensation reaction. A range of materials can be cast into the cured silicone mold: plaster, polyurethane and polyester resins are materials typically used.
