Castaldo Liquacast

Is a 0% shrinkage room temperature vulcanizing liquid rubber that lets you make molds of delicate objects that would not survive the heat and pressure of the normal vulcanization process. Typical uses include making molds of CAD-CAM, RP and SLA resin models, wax carvings and wax injections. Also possible are objects from nature - leaves, plants, flowers, fruit, insects - anything!

Easy to Pour!

Castaldo Liquacast is an easy-flowing two-part liquid room temperature vulcanizing compound that makes tough, strong, flexible rubber molds in 18 hours at  normal temperatures. It can be cured in as little as 90 minutes at temperatures up to 66°C / 150°F. Unlike traditional silicone liquid molding rubbers, Liquacast is easy to pour, easy to mix and easy to vacuum de-bubble because of its low viscosity.

Costs less!

Liquacast produces superior molds but cost only a fraction of the price you may be accustomed to paying fro traditional RTV compounds.

Stronger, Tougher molds!

Molds made of Liquacast are much stronger, tougher and longer lasting than those made from traditional liquid rubber compounds. Liquacast molds are production molds that can be used with 100's of times, not intermediary or prototype molds that can be used only once or twice.

One Step Mold-Making!

Liquacast avoids the need to cast a delicate wax or resin model in silverland then make a traditional rubber mold from the casting. A process that can take serveral days and result in multiple levels of shrinkage and an inevitable loss of detail.

Easy to Use!

Liquacast is easy to use and requires no specialized equipment, making it ideal for those without a vulcanizer. It can even be use without a vacuum - merely coat the model with a brush dipped in Liquacast and inspect it for bubbles before completing the pour. Any bubbles found can be easily be pricked with a pin or similar tool. Models can also be dipped in Liquacast and then inspected for bubbles.

Molds made from Castaldo Liquacast liquid molding rubber will last many years if stored properly. For best results store finished molds in airtight containers such as the kind sold for food storage.
