Mitreapel Silicone mould release spray (2 x 13.5 fl oz) release agent aerosol spray, 1 pack

This product works great..! Left no residue and speeds up the process.

This is probably the 3rd or 4th mold release spray I've tried. It's one of the least expensive and also, in my opinion, the best. It let's my resin castings slide out of their silicone molds just as well if not better than than the others but the real advantage is in how the spray can is designed...Every other spray I've used comes out way too fast and forceful. So much spray is released at once and at such a high velocity that much of it gets shot right back out of the mold. I end up having to very carefully manage the nozzle in a futile effort to control the discharge (get you minds out of the gutter people!)Anyway this can is way better! The spray comes out in a nice, easily controlled mist which lands and settles perfectly in my molds with no back splash or wasted spray. I feel like these cans will last twice as long simply because nothing gets wasted when using it. The other major advantage of this is that there's much less spray and smell left lingering in the air to breath in. My lungs are thanking me just just as much as my wallet with this stuff!

I use it in both my silicone and homemade HDPE molds and it works great. It also works great for a lubricant on the tables on the table saw & planer. As well as I've recently started using it on my CNC bits to keep residue from building up as it works better than the Bostic blade lube IMO and cheaper. Only bit of criticism is it used to have an odor like lemon Pledge furniture polish, now it has some weird sweet odor that is not pleasant.

Before shaping the molds to a final form, a cast of the 2-part epoxy was needed in rough form. At first, the spray was forgotten to be applied when making the silicone molds from the original forms. This was a disappointment yet later became a comparison for when the rough form castings were made with the 2-part epoxy. Without the spray, did not make it impossible to release the rough forms however more difficult than when the spray was used. Since the 2-part epoxy dries water like makes visible that the restraining force for release was due to the vacuum between the dried epoxy and the silicone mold. Since only a minute amount of spray was used after a good shaking, the expenditure for the spray release was worth it.

Awesome product but you have one shot at lining up your pieces. Doesn’t do well on rubber or cloth but wood, plastic etc it’s on there and done. Wear gloves or you’re eventually going to glue yourself to yourself or your project or anything you touch. Would definitely recommend this product but would advise trying it on scrap first to get an idea of just how fast it bonds.
