Model Making Materials

OOMOO 25 silicone rubber.

OOMOO 25 is good ‘entry level’ product: straightforward to use but there is a compromise on strength/durability. It is good for making simple one or two piece block moulds.

• One-to-one by volume mix ratios (no scale necessary).
• Low viscosity for easy mixing & pouring, vacuum degassing is usually not necessary.

• Shore hardness: 25A 
• Shelf life: OOMOO series silicones have a limited shelf life and should be used as soon as possible.
