What are Addition Hardening Cast Rubbers?
Addition-curing casting rubbers are a special class of silicone rubber that, after curing, deliver a beautiful, rubber-like, and flexible result. Here are some key features:
Curing: These silicones cure through a reaction with a platinum catalyst. This process ensures a stable and durable structure.
Flexibility: Addition-curing casting rubbers are highly flexible and can be easily deformed without losing their integrity.
Durability: They remain durable for many years and do not shrink after curing.
Applications of Addition-Curing Casting Rubbers:
Skin-Friendly: This type of silicone is often suitable for skin contact and does not shrink. Special versions can even be used as molds for food items like chocolate or cake.
Creative Uses:
- Create fun shapes for edible treats using chocolate.
- Craft silicone masks like a pro.
- Make your own seals or silicone liners.
- Create molds for miniatures or sculptures and more using this versatile platinum silicone!
Color Options: Clear and colorless variants can be beautifully tinted. Even white silicones can achieve a nice color effect.
Extra Fun Factor: You can also fill these silicones with glow powder, hollow glass beads, glitter, or magnetic powder for even more fun applications!
