OOMOO 25 Silicone Rubber

No Vacuuming Ð No Scale Ð OOMOOª 25 & 30. OOMOOª 25 & 30 are easy to use silicone rubber compounds that feature convenient one-to-one by volume mix ratios (no scale necessary). Both have very low viscosity for easy mixing and pouring, and vacuum degassing is not necessary. Both products cure at room temperature with negligible shrinkage.
