Product Description
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 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.
UreCoat™
UreCoat™ is a two component urethane (A+B) that can be mixed and brushed onto a variety of surfaces to provide a flexible, tough and impact resistant coating. Mix ratio is 100A:10B by weight (gram scale required), pot life is 8 minutes, re-coat time is 30 minutes, tack free time is 2 hours and full cure is 16 hours at 73°F/23°C. UreCoat™ contains no phthalates or VOC's.
