Ready to make some molds?

This AM 128 Silicone Rubber RTV Kit is a favorite for crafters, artists, and DIYers.

It's a tin-based, pourable silicone rubber with a Shore A hardness of 28—flexible but durable.

You get a total of 8.8 pounds to work with.

Pot life is about 45 minutes, so you have time to mix and pour, and demold time is around 24 hours.

It works great for casting all sorts of materials: urethane resins, plaster, fine cement, wax, and even soap!

Just use a petroleum jelly mold release (not silicone-based) for best results, especially with glass or other silicones.

Perfect for making custom molds for candles, soap, figurines, or concrete crafts.

Whether you're a beginner or a pro, this kit gives you high tear resistance and reliable results every time.
