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.
Compared to the other Mold Max® products, Mold Max® 25 has a lower viscosity Part A, making the rubber easier to mix and easier to vacuum de-gas.
The working time for the Mold Max® 25 is an extra-long 60 minutes for large mold pours or for pouring several molds from a single batch of rubber.
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® 25 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).
