Purupox 1:1 Liquid Silicone Rubber for mold making is popular for ease of use, versatile, and the quality of the molds produced. This silicone is a popular choice for both beginners and experienced crafters due to the straightforward preparation and reliable performance.
Key features:
- Ease of Use and Simple Mixing: A primary advantage is the 1:1 mix ratio by volume, which eliminates the need for precise weighing scales, making the process simpler and less prone to error . This "blend and set" approach is particularly appealing for those new to mold making.
- Excellent Detail Replication: This silicone is highly valued for the ability to capture even the finest textures and intricate details from the original master. This ensures that the resulting molds produce accurate and high-quality castings.
- Versatility in Casting Materials: This 1:1 silicone is compatible with a wide variety of casting materials, including resin, wax, soap, chocolate, sugar, plaster, concrete, and even low-temperature melt metal alloys . This broad compatibility makes them suitable for numerous projects and industries.
- Durability and Longevity of Molds: The silicone molds produced are known for being soft, strong, and tear-resistant, exhibiting very low long-term shrinkage. This contributes to the molds lasting a very long time.
- Heat and Freeze Resistance: This platinum-cured silicone offer excellent temperature resistance, withstanding temperatures up to 200 C and being freezer-friendly. This makes them suitable for applications involving heat, such as baking, or for casting materials that generate heat during curing.
- Food-Safe Options: This silicones is food-compliant, making them safe for culinary projects like chocolate, sugar, or ice molds.
- Optional Degassing: While degassing is recommended for the highest level of detail and to avoid air bubbles, this 1:1 silicone have relatively low viscosity, making vacuum degassing optional for most applications. A uniform flow during pouring can help minimize entrapped air.
- Work & Cure Times: Work time after mixing is around 20-40 minutes while cure/demolding time is between 2-4hours, depending on the temperature.
- Non-Toxic and Skin-Safe: This 1:1 silicones is non-toxic and skin-safe, making it suitable for direct skin contact applications.
- Cost-Effectiveness: The ability to make reusable molds can save money compared to purchasing expensive pre-made options, highlighting the long-term value of this product.
