Smooth-On Universal Mold Release - 14 Fluid Ounce Aerosol Can

I have a few large silicone molds for projects. I used to use epoxy tape to prevent sticking of the epoxy in the seams. I didn't think a release spray would work and didn't want to lose my project (or the mold) because of bound epoxy. I finally used this on the sides of one of the molds because the silicone surface had some scratches that might promote sticking. The spray worked so well that I only used it for the next new pour. There was essentially no sticking. The piece popped out so easily ... I'll never go back to tape for this. I recommend it strongly and will continue to buy. No complaints; great product.

The media could not be loaded. I use this in my cement molds and it works like a charm I also have used this in resin and I can honestly say I have no complaints

It works fantastic; beeswax slips right out of the mold.

The first thing I can say about this product is that it works. I used it to release urethane rubber from various types of molds. The nozzle stays clean even if I forget to wipe it down/clear it. It has a very even, fast spray meaning it only takes a half second to evenly coat a small to medium sized mold, and with the amount in this can it'll probably expire before I use it all. It does have a smell and you're not supposed to breathe in the fumes (work in a well ventilated area per the instructions) but the smell wasn't unpleasant, just strong, and it dissipated quickly. I didn't have any problems with beading or running together even if I put a generous coat on. It does leave the object molded slightly greasy/oily, but for a clean extraction it's a very, very small price to pay. Just wipe it down and you're good to go. I didn't use it with any other types of molding materials, just urethane rubber, so take my glowing review with a grain of salt.

perfect for the job and exactly as described.

Used this for epoxy pour, it worked well.

Satisfied customer.

This stuff is great! Not sure why people are saying it doesn’t work for silicone molds- I’ve never had an issue with my resin bonding to molds as long as I’ve been using this. The only thing to make sure of is that you spray it outside!! If sprayed above hard floors inside, it makes it EXTREMELY slippery. I couldn’t figure out why the hell myself and my family kept slipping and falling in the entry to my art room and the hallway leading to it, but finally figured out that me spraying molds inside the room, even in small amounts, was the culprit.
