Smooth-On OOMOO 30 Tin-Cure Silicone Rubber Trial Unit
No Vacuuming--No Scale--Easy To Use--OOMOO 30 is an easy to use tin cure silicone rubber compound that features a convenient one-to-one by volume mix ratio (no scale necessary). It has low viscosity for easy mixing and pouring vacuum degassing is not necessary. This product cures at room temperature with negligible shrinkage. OOMOO 30 has a 30-minute pot life, with a six-hour cure time.
OOMOO silicones do not have great tear strength. They are good for making simple one- or two piece block molds. If you require a high-tear strength silicone, Mold Max silicones are recommended. OOMOO 30 is suitable for a variety of art-related and industrial applications including making one and two-piece block molds for sculpture and prototype reproduction, casting plaster, resins and wax. OOMOO silicones are also suitable for electrical potting and encapsulation applications.
Mold Performance & Storage--The physical life of the mold depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials such as concrete will quickly erode mold detail, while casting non-abrasive materials (wax) will not affect mold detail. Before storing, the mold should be cleaned with a soap solution and wiped fully dry. Two part (or more) molds should be assembled. Molds should be stored on a level surface in a cool, dry environment.
