Important Materials

This kit utilizes platinum-cured liquid silicone rubber. Platinum-cured silicones are known for their superior quality, durability, safety (non-toxic, odorless), and excellent replication of detail compared to tin-cured silicones. They are also more resistant to heat and chemicals.

Essential Factors to Consider

• Quantity: The 22lbs size of this kit is substantial, suitable for larger projects or multiple mold-making sessions. Ensure the quantity meets your project needs.
• Mix Ratio: A simple and forgiving 1:1 mix ratio, as found in this LET’S RESIN kit, is ideal for ease of use and consistent results.
• Working Time and Cure Time: Understand the working time (pot life) before the silicone begins to set, and the cure time (demold time). The “4H Faster Curing” suggests a relatively short cure time, which is advantageous.
• Compatibility with Casting Materials: Confirm that the silicone is compatible with the materials you intend to cast (e.g., resins, plaster, soap bases). This kit is versatile, supporting various casting materials.

Budget Planning

Silicone mold making kits can vary significantly in price based on quantity, brand reputation, and specific features. The 22lbs size of the LET’S RESIN kit indicates a more substantial investment, but often provides better value per pound for frequent mold makers.
