Silicone Mold Release, 12 Wt Oz, (Pack of 12), 03300CS

This is the second time I've bought this. Works so well.

This product works extremely well. I used it when epoxy bedding an item and had zero sticking issues after applying a coat, letting it dry and then applying a second coat before use. It drys pretty fast so doing two coats is no problem. if you are doing relatively small jobs, one cal lasts a long time.

Worked great in this mortar concrete mix. The slab came out very easily with only tiny imperfections. This was my first time molding anything and using concrete so I was amazed how well it came out.

I’d say if you were molding something, it works great and your piece comes off relatively easy. But if you’re making a two part mold, silicone to silicone, this does not work. My piece ended up getting trapped inside. I had to cut it out carefully so I don’t damaged the piece inside. 4 stars for not making it clear that this does not work for two part silicone molds. Yes temperatures were ideal, and I shook the can vigorously as usual.

Used this on silicone molds that are very intricate and hard to unfold. Made unmolding much easier. Does have an odor and cloud flume but it dissipates quickly.

I think this product is very well designed and works exactly as advertised. Also, I think it's very expensive for what you get so use it sparingly.

I use this CRC product for my vintage car collection, I spray it on all the parts that may be susceptible to rust or corrosion. It leaves a microscopic silicone coating that drys and is not tacky (like WD-40 or others) and protects parts from corrosion. Also excellent on my motorcycle and bicycle. Try the CRC food grade silicone spray also.

I gave the product 3 stars because I'm not sure if it was the right product for the application (or user error) but it really failed me. I used the product as a mold release on melamine for an epoxy poor and the mold almost completely ruined the project by sticking to the piece. I used it on some samples with mixed success but on the two actual pieces it had a failure rate around 90% on the sides and 50% on the bottom. Would not recommend for those types of projects...
