YJS-645 is is hard and not very flexible, with a 45A Shore hardness. It is firm enough to hold heavy concrete parts yet still has flexibility for demold. A good option for making molds for rapid prototyping, wax casting (foundries and candle makers), architectural restoration and for casting concrete. It can also used as casting materials.

1. Description
YJS-645 is a two-component 1:1 Mix addition (platinum) cured RTV silicone rubber which cures at room temperature. YJS-645 is is hard and not very flexible, with a 45A Shore hardness.
