Description
This tin-cured silicone rubber compound is known for its exceptional working properties and long library life.
Mold Max™ 10 can be pigmented with Silc Pig™ silicone colorants.
The working time for the pourable silicones is 45 minutes, and they cure overnight at room temperature. Vacuum degassing is recommended to remove entrapped air.
Features
- Reproduces the finest detail.
- Suitable for industrial and art applications, including molds for prototypes, furniture, sculpture, and architectural elements.
- Can be thickened with THI-VEX™ for brush-on applications.
- Compatible with casting materials like wax, gypsum, low melt alloys/metals, and urethane, epoxy, or polyester resins without a release agent.

Instructions
Mixing & Measuring
Weigh Part A & B components using a gram scale. Pre-mix Part B thoroughly to re-disperse pigments. Dispense required amounts of parts A and B into a mixing container and mix for 3 minutes, scraping the sides and bottom. Vacuum degassing is recommended to eliminate entrapped air. Your vacuum pump must pull a minimum of 29 inches of mercury (or 1 Bar / 100 KPa).
Pouring / Curing / Post Curing
Pour the mixture in a single spot at the lowest point of the enclosure. Allow the mold to cure overnight (at least 16 hrs) at room temperature (23°C) before demolding.
Post-curing the mold for an additional 4 hours at 65°C will eliminate residual moisture and alcohol.
Allow mold to cool to room temperature before using.
Thickening and Thinning
THI-VEX™ is used for thickening for vertical surface application.
Apply a thin coat of rubber and wait for it to become “tacky” before applying the next coat.
Silicone Thinner™ can lower the mixed viscosity but should not exceed 10% by weight of the total system (A+B).
Accelerating
Accel-T™ silicone rubber accelerator can be used to accelerate the cure time.
Note: working time is reduced in proportion to the amount of Accel-T™ added.
Safety & Handling
Use in a properly ventilated area. Wear safety glasses, long sleeves, and rubber gloves. Use vinyl gloves only, as latex gloves will inhibit the cure. Store and use material at room temperature (23°C).
Storage
Clean the mold with a soap solution and dry fully before storing. Store molds on a level surface in a cool, dry environment.
