Magikmold® P-520 is a soft, room temperature curing, platinum-cured silicone rubber compound designed for the manufacture of flexible molds. It has a 1:1 mix ratio, Shore A20 hardness and is low in viscosity.
This silicone has a fast demold time of 1 hour, and the transparency of Magikmold® P-520 is useful for molds that need to be cut after cure because it’s easier to see the model through the silicone.
This is a pourable rubber, but it can be easily thickened with silicone thickener for brush-on application.
