OOMOO 25 Easy-to-Use Molding Silicone

OOMOO 25 Easy-to-Use Mold Silicone No vacuuming – No measuring – Easy to Use… OOMOO® 25 is an easy-to-use silicone compound with a one-to-one mixing ratio by volume (no scale required). It has a low viscosity for easy mixing and pouring… No need for vacuum degassing. This product cures at room temperature with very small shrinkage. OOMOO® 25 offers 15 minutes of application time and 75 minutes of cure time.

For Novice Mold Makers - OOMOO® silicones do not have great tear strength. But they are suitable for making simple one- or two-piece block molds. If you need a high tear strength silicone, it is recommended to use Mold Max® silicones.

OOMOO® 25 is suitable for a variety of artistic and industrial applications, including plaster, resin and wax castings, prototypes, one- and two-piece block moulds. OOMOO® silicones can also be used for electronic circuit boxes making and encapsulation applications.
