Castaldo Silicone Rubbers

Molds made with silicone mold rubber can be cut very easily and smoothly and are resistant to tearing. They offer sufficient strength for complex models. They provide shine to waxes and do not require the use of silicone release spray or powder; the rubber separates easily from the wax. Thanks to its putty-like consistency, it is easy to spread into the mold and compress by hand.

In addition to the standard dark yellow color, it is available in various colors. The product sold with mixed colors is called Gelato.
