    • 【PREMIUM MOLD MAKING SILICONE MATERIAL】: LET'S RESIN 25A silicone mold making kit is designed for the manufacture of flexible & firm molds. It is high-performing room-temperature curing (RTV), two-part, platinum-cured silicone rubber, which is a safe & premium silicone material and exhibits extremely low shrinkage, allowing for fine details and patterns to be captured. This mold making kit comes with part A and part B, each containing 295g/0.65lb of liquid silicone rubber.
    • 【HIGH TEAR STRENGTH & LONG LIFE SPAN】: The silicone molds finished with LET'S RESIN 25A mold making silicone rubber feature medium-hard & flexible, not easily breaking. It will be flexible enough to de-mold the items easily and also firm enough to maintain the structure of the silicone mold. The silicone molds have a very long life span, which can be used up to 500~1000 times.
    • 【EASY BLEND & FAST CURING】: With the bicolor appearance, you can easily see whether part A and part B are mixed thoroughly; Just mix Part A and Part B with a ratio of 1:1 by weight, then stir the silicone for 3~5 minutes; the working time is within 30 minutes and the cure time is 3~ 6 hours at room temperature. The final curing time varies on mold size, thickness, and temperature; heat cure will also shorten the curing time. (NOTE: please go to the FAQ part to learn more about mold making tips before use)
    • 【LOW VISCOSITY & SELF-DEGASSING】: No vacuum machine is necessary! The bubbles of silicone for mold making will automatically disappear within 2 hours at room temperature due to its low viscosity feature. Bubbles tend to occur in hot temperatures. To reduce all micro-bubbles, you can seal and store the mixed molding silicone in the refrigerator for 1 hour while curing, then continues to cure at room temperature.
    • 【WIDE APPLICATION 】: Silicone molds made by LET'S RESIN silicone rubber mold making is very ideal for art craft use, suitable for various casting materials, including urethane plastic and rubber, wax, polyester casting resin, plaster, concrete, epoxy, soap, and some low melt metals.
