Smooth-On 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™ silcones 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.
Features
- Mold Max™ Silicones will reproduce the finest detail and are suitable for a variety of industrial and art related applications including making molds for reproducing prototypes, furniture, sculpture and architectural elements.
- Mold Max™ 30 can be thickened with THI-VEX™ additive for brush-on applications.
- Mold Max™ Silicones can be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins (without using a release agent).
