How it Works

SiliNOT! makes mold making simple and forgiving. Just melt it down, pour it over your object, let it cool, and start casting,no mixing, no curing, no stress.

"I have wasted so many hundreds of dollars on silicone mixes only to throwaway"

— Nicole

Start by gently heating SiliNOT! until it fully melts into a smooth, pourable liquid, then carefully pour it over or around your object to capture its shape and surface detail. Allow the material to cool and solidify into a flexible mold, then remove the original and begin casting your parts with confidence. For best results, temperature guidance, and project-specific tips, follow our detailedHow-To Guidefor step-by-step instructions.

Fantastic for reusable moulding

Sets to an excellent firmness, highly flexible but doesn't crack or split. Once you've got it in smaller amounts it re-melts quickly and easily in the microwave and resets just as quickly and easily. Highly recommend. Sets to an excellent firmness, highly flexible but doesn't crack or split. Once you've got it in smaller amounts it...

Easy to use!

I have extensive experience with mold making and I've tried a bunch of different mold-making materials, but SiliNOT! really stands out. The smell is really not that bad, which is a big plus for me since I often work in small spaces.

Really easy to use

It's super easy to use and i can make a ton of different things. I use this to make reusable picky pads and used the smallest amount for a good sized pad. It melts quickly and cures quickly. I haven't had any issues, and I can get so much use out of it. It's super easy to use and i can make a ton of different things. I use this to make reusable...

Remelt and Reuse Over 35x

Reuse for the same casting multiple times, no need to remelt and remake after each use. If you make a mistake or want to try again, simply remelt and remake the mold up to 35 times.

That's 35x cost savings versus 2-part silicone. 30x less single use plastic entering landfills.

What is it?

SiliNOT!® is a reusable thermo-bioplastic mold-making material made from food-grade, non-toxic ingredients. It melts with heat, flows to capture detail, and solidifies as it cools, without curing or chemical reactions, so it can be remelted and reused repeatedly without material loss. This makes it a biodegradable, low-waste alternative to silicone that’s safer, more forgiving, and more cost-effective for makers of all levels.

FAQ

What is SiliNOT! ?

All SiliNOT! products are produced from food safe ingredients, the same ones you eat daily! Our formulas are 100% Non-Toxic and Plastic Free.

How many times can I really remelt your SiliNOT!

You can remelt it 30 times. In reality, with proper care by following the heating instructions, you can remelt it hundreds of times. There is nothing hindering the remelt process except over heating, if you exceed 200F too many times it will deactivate the setting agent and won't set up properly.

If it melts at 150F, how do I cast higher temperature setting materials.

For higher temp. casting, we recommend first putting the SiliNOT! mold in the fridge or freezer. Allow it to chill completely, SiliNOT! won't freeze or become brittle when cold, it will be the same strength and flex. Once it's cold, then start casting with it. For smaller or thinner molds, this may not be needed as the heat the casting material generates just isn't enough to melt the SiliNOT! but for thicker castings, try that method. And remember, if you make a mold and it doesn't work, you can always remelt and try again :)

Does it cure against 3D Printed Resin?

Yes! Unlike some silicones, SiliNOT! doesn't experience cure inhibition against any material.
