Smooth-OnUniversal™ Mold Release Spray, 14 fl. oz. 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.

Used this for epoxy pour, it worked well.

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.

Satisfied customer.

I use this mold release for epoxy resin projects. I've never had any issues when using it - everything always comes out cleanly! The only thing I would say is maybe to either use it in a well ventilated area or wear a mask when spraying it (it doesn't have a super strong odor or anything, it just gets all in the air). Other than that I love it! Also the cans last a long time for me - you don't need much product.

I use this product every day in my shop, to create resin castings. I am a professional mold maker, and model maker. Smooth-On products are the best in opinion, and their signature mold release spray is very easy to use. I make silicone and urethane molds for studio scale models, so the spray is very convenient. It goes on evenly, sets up in 5 minutes, and releases the castings very easily.
