Smooth-On Silicone Rubber Products have superior release properties and cover a broad spectrum of industrial and art related applications. These include making molds to reproduce architectural ornamentation, sculpture, prototype models and ceramics. You can cast a variety of materials into these molds including plaster, resins and low melt metal alloys all without applying a release agent.

OOMOO 30 & 25 - OOMOO® 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 usually not necessary. Both products cures at room temperature with negligible shrinkage and have good tear strength.
OOMOO® 30 has a 30-minute pot life, with a six-hour cure time. OOMOO® 25 is a faster version, with a 15-minute pot life and 75 minute cure time. OOMOO® 25 & 30 are suitable for a variety of art-related and industrial applications including making molds for sculpture and prototype reproduction, casting plaster, resins and wax.

Mold Max Series  - Mold Max® Silicones will reproduce the finest detail and are suitable for a variety of industrial and art related applications including making molds for reproducing prototypes, furniture, sculpture and architectural elements. Mold Max® silicones can also be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins (without using a release agent).  Durometer: 10A, 20A, 30A, & 40A

Dragon Skin - Dragon Skin® and Dragon Skin Q® are high performance platinum cure silicone rubbers that can be mixed 1A:1B by weight or volume and cure at room temperature with no shrinkage. Cured Dragon Skin® is very soft, very strong and very “stretchy”. It will stretch many times its original size without tearing and will rebound to its original form without distortion. Dragon Skin® is water white translucent and will accept pigments for creating color effects. Dragon Skin® has a pot life of 20 minutes and a demold time of 5 hours. In A Hurry? Dragon Skin® Q (Q = Quick) has a pot life of 8 minutes and a demold time of 75 minutes. Durometer: 10A

Smooth-Sil Series - Smooth-Sil® 935, 940,  950 & 960 (NEW) weight are mixed 100A:10B by and require an accurate gram scale or triple beam balance. Smooth-Sil® 945 is mixed 1A:1B by volume and require no scale for measuring.  No post curing is required (though it is recommended in some circumstances) and the material cures with virtually no shrinkage. Ideal for reproducing exact detail of any model. These rubbers are suitable for making production molds of any configuration, large or small. Materials such as urethane, urethane foams, epoxies, polyester resins, wax and low-melt metal alloys (tin, pewter) can be cast into Smooth-Sil® Series Silicones without application of release agent. Durometer: 35A, 40A, 45A, 50A & 60A

Sorta-Clear Series - SORTA-Clear®  is a premium water white translucent silicone rubber (platinum catalyst) that cures at room temperature with no shrinkage. SORTA-Clear® 40 has a Shore hardness of 40A and features exceptional tear and tensile strength. Rubber clarity is especially useful when extracting models via cutting. SORTA-Clear® rubber is ideal for making prototype, jewelry or other molds of any configuration where model visibility is important. 

Eco-Flex Series  - Ecoflex® Rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex® Rubbers are mixed 1A:1B by weight or volume and cure at room temperature with negligible shrinkage. Rubber also cures without a "tacky" surface. Low viscosity ensures easy mixing and de-airing, or you can choose to mix and dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very "stretchy", stretching many times its original size without tearing and will rebound to its original form without distortion. Ecoflex® Rubbers are water white translucent and can be color pigmented with Silc-Pig® pigments for creating a variety of color effects.
Durometer: 00-10A, 00-30A, 00-50A, 5A

Rebound  - Rebound®  is an easy-to-use platinum-cure silicone rubber that self-thickens for making brush-on molds of almost any model. Mixed 1A:1B by volume (no scale necessary), Rebound®  can be applied with a brush or spatula to vertical surfaces without sagging and will cure with negligible shrinkage to a soft, flexible rubber.

3 to 4 layers are all that is necessary to make a strong, durable production mold for casting wax, gypsum, concrete or resins (urethane, polyester, etc.) And because Rebound® 25 is a platinum silicone, it will last for many years in your mold library. Applications include reproducing sculpture, architectural restoration, making candle molds, etc
