Reliable platinum silicone for UV resin masters, Defiant 25 is engineered to solve a common problem in mold making: platinum silicone curing inhibition caused by UV resin prints. The formula is highly resistant to this effect, so molds cure cleanly and consistently with minimal extra steps.

Balanced Shore 25A feel with Shore 25A hardness, the silicone is flexible enough for easy demolding while still holding detail and shape. It’s a practical all-round hardness for most casting and craft projects.

Easy mixing, kit sizes, and pouring. The kit uses a simple 1:1 mix ratio by weight or volume. Customers can choose between a 1 kg kit (Part A 500 g + Part B 500 g) and a 2 kg kit (Part A 1000 g + Part B 1000 g). The thin viscosity flows easily into fine details and makes bubble removal simpler, even without a vacuum chamber.

Durable, heat-resistant molds. Defiant 25 offers strong tear resistance for repeated use, and it withstands elevated temperatures (up to around 200°C), making it suitable for casting resin, wax, soap, candles, and more.

Food-safe applications. After proper curing, Defiant 25 meets FDA food-safe requirements, enabling molds for chocolate, candy, baking, and other culinary uses alongside standard craft applications.
