Product Description

Ecoflex™ 5

Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage.  Low viscosity ensures easy mixing and de-airing. 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.

TASK™ 14

TASK™ 14 is a fast setting two-component urethane that cures quickly to black semi-rigid plastic. TASK™ 14 offers a longer pot life (10 minutes) and demold time of 45 minutes.

With a Shore value of 50D, these semi-rigid plastics are used for a variety of industrial applications including fast mold making, fast model duplication, prototyping, durable miniatures, black props and special effects, or making parts that are impact resistant. Fully cured castings are tough, durable and chemical resistant.

For Best Results… Do not cast TASK™ 14 into platinum cure (addition cure) silicone molds.

OOMOO™ 30

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.

For The Novice Mold Maker - OOMOO™ silicones do not have great tear strength. They are good for making simple one- or twopiece 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.
