Why is the release performance getting worse when I use silicone mold casting resin?
When casting with platinum-cured silicone material, the silicone mold will initially exhibit good mold release characteristics. Depending on the cast material, the lubricity of the silicone mold may decrease over time, making demolding more difficult. For soap, candle, or food, no release agent is necessary. However, when casting with polyurethane, polyester, or epoxy materials, a release agent is recommended to prevent sticking during release and make separation easier.

Is your silicone safe and does it cause any harm to the body?
The curing agent in RTV-2 tin-cured silicone formulations can cause skin or eye irritation upon direct contact. Therefore, it is essential to take appropriate safety precautions. The workplace should maintain good ventilation according to the Threshold Limit Value (TLV) standards specific to each country.

Do I have to have a vacuum pump? Can I prevent air bubbles from forming in my finished silicone mold without using a vacuum pump?
Since the viscosity of tin-cured silicone is greater than 10,000cps, it is considered a medium-viscosity liquid silicone and can easily generate air bubbles during mixing and stirring. Therefore, it is best to use a vacuum pump for defoaming. If your production process involves brush-on application, a vacuum pump may not be necessary for defoaming.

Is it okay to make a cast on top of the polystyrene? And how much liquid silicone material is required to create a shape of 100cm x 60cm?
Of course, it works on polystyrene, and tin-cure silicone works on almost any material. To determine the required quantity, you can calculate based on the liquid silicone's density (1.2g/cm3).

Is this silicone material suitable for cement molds?
This type of silicone material is highly suitable for creating cement molds. You can select a tin-cured silicone material with a hardness of 20-30A depending on the size of the cement piece. If you require more information on this, please do not hesitate to contact us.
