  • Formulated for mold making & casting with URETHANE RUBBERS and POLYURETHANE PLASTICS
  • When used properly, Universal Mold Release Spray will prevent adhesion, release mold rubbers from properly prepared models, and help lengthen production life of mold rubber.
  • NOTE: DO NOT APPLY UNIVERSAL MOLD RELEASE ON YOUR MODEL IF YOU ARE MAKING A SILICONE MOLD
  • Perform a small-scale test to determine suitability for your project & follow technical bulletin instructions available at smooth-on.com

Description

Universal Mold Release Agent is formulated especially for mold making and casting, and works well with most liquid rubber and liquid plastic products. It will release mold rubbers (such as polyurethanes and polysulfides) from properly prepared models. Sealing porous models (wood, plaster, concrete) or certain modeling clays (containing water or sulfur) with Smooth-On SuperSeal or other sealer (such as spray shellac) may be necessary. Universal Mold Release is effective over a broad temperature range from 70°F to 500°F. If using silicone rubber, seal model surface with SuperSea only. Do not use Universal Mold Release. Universal Mold Release also easily releases a variety of casting materials (epoxies, Smooth-On liquid plastics, etc.) from cured rubber molds. This product has a limited shelf life and should be used as soon as possible. Properly used, Universal Mold Release improves molding efficiency for a variety of casting applications and will actually lengthen the life of your production mold. CONTENTS FLAMMABLE: Keep product away from flame and all ignition sources. Use this product in a properly ventilated area with at least room size ventilation. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Store and use material at room temperature (73°F/23°C). Apply a Sealing Agent if Necessary - Porous surfaces (concrete, plaster, etc.) often require a sealing agent followed by a release agent when releasing liquid mold making materials. Follow directions on the mold material technical bulletin before proceeding. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question. Refer to technical bulletin for more information available at Smooth-on website. Adult Supervision Required. Keep Out of the Reach of Children.

Five stars
Works as expected.

Does a good job.
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. ... show more

Great release- be careful where you spray it!!
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. ... show more

You want your mold to let go, come on now.
A mold ain't a mold if it holds onto your original for dear life. Then you just got a block of rubber and you're out one original piece. Spray that sumbuck with a light dusting of this and you're golden. Only if it's plastic, metal, or some other non-porous material. This isn't for wood.
