Magikmold® U-760 is a room-temperature curing (RTV), two-part, liquid urethane rubber designed for the manufacture of flexible molds and parts. This rubber has a Shore A60 hardness, 10-minute pour time, and 16-hour demold time.
Magikmold U-760 is a pourable rubber, but can be thickened with Fumed Silica to make brush-on molds.
FOR INDUSTRIAL/PROFESSIONAL USE ONLY.
Common Applications & Casting Materials
Magikmold U-760 molds are often used in:
- Concrete Casting for home decor, sculpture, and more
- Concrete Texturing with U-760 stamp and texture mats
- Gypsum Plaster Casting for artistic and restoration projects
- Wax Casting for lost-wax processes
- Resin Casting for sculpture reproduction, prototyping, and much more
Magikmold U-760 rubber can also be used to make finished parts, including:
- Prototypes parts
- Industrial parts like gaskets and bushings
Release agent is generally not necessary for casting plaster and some waxes in U-700 Series molds. For resin casting (e.g., Magikast® Fast Cast Resins), first spray the mold with a suitable release agent (e.g., Stoner E-236 Urethane Mold Release) and brush with a dry brush to ensure thorough coverage. For concrete casting, use a suitable form release – avoid solvent-containing release agents as they can cause the mold to shrink or swell.
