Product Description

Mold Max™ 30

Mold Max™ Silicones are tin-cured silicone rubber compounds that have exceptional working properties and library life. Mold Max™ Silicones feature Smooth-On’s exclusive “Libra™” catalyst for long library life. Mold Max™ silicones can be pigmented with Silc Pig™ silicone colorants. Pot life for the pourable silicones is 45 minutes and they cure overnight at room temperature.

Vacuum degassing mixed material using a vacuum pump and chamber to remove entrapped air is recommended.

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.
