PlatSil 73-20 is a low viscosity (2000 cP) platinum silicone mold rubber that is clear/translucent and offers an easy, 1:1 mix ratio. It is a Shore A~20 hardness, making it quite soft and flexible for the most intricate and delicate mold making requirements. Since it is a platinum silicone mold rubber, it does not shrink on cure and should be tested for cure inhibition against any surface before a project is undertaken. PlatSil 73-20 has a 5-minute working time and is able to be demolded in 1 hour at room temperature.
