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.
Metalset™ A4
Metalset™ A4 is a powerful epoxy adhesive that has been used for years by all branches of the U.S. Military as well as every major airline and auto manufacturer in the world. Metalset™ A4 is used for hundreds of industrial bonding applications and offers excellent adhesion to porous or non-porous surfaces. It can be applied to vertical surfaces without sagging and cures overnight with negligible shrinking.
Once cured, Metalset™ A4 offers good machining qualities (sanding, drilling, tapping), and resists alkalies, dilute acids and solvents. Applications include stopping leaks in pipes, valves and tanks (i.e. car gas tanks), bonding like and unlike surfaces, filling metal joints, dents, etc., anchoring bolts in wood, concrete, and repairing metal surfaces.
Bell Spec - Metalset A4 meets all quality requirements and can be certified to Bell Spec 299-947-099 Rev. D (see below for details)
