It excels at releasing polyurethanes and polysulfides from prepared models, works across a wide temperature range (70°F-500°F), and extends mold rubber life. Ideal for use with porous materials when paired with sealers, it delivers consistent, efficient mold separation to elevate your production quality. ## Description If you've ever been to the movies, admired a piece of sculpture, marveled at detailed architectural ornamentation or used a telephone; then you've encountered the handiwork of people who use Smooth-On rubbers, plastics, foams and other products to turn their ideas into 3-dimensional reality. 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 may be necessary. Universal Mold Release is effective over a broad temperature range from 70°F to 500°F. Features If using silicone rubber, seal model surface with SuperSeal 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. Adult Supervision Required. Keep Out of the Reach of Children. Review: Effective but a bit pricey​ - Works well, but it's a bit pricey. Effective for most mold-making tasks, but there are more affordable alternatives available.​ Review: Definitely Recommend - Works great getting resin projects out of our Tyvek tape lined molds with very little effort ## Features - 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. - Some porous models such as wood, plaster, concrete, stone or certain modeling clays containing water or sulfur may need to be sealed first prior to applying mold release with Smooth-On SuperSeal or other sealer. - Will help to lengthen the production life of your mold rubbers if properly used - Do not use if making a silicone mold. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004BNHLOK | | ASIN | B004BNHLOK | | Batteries Included? | No | | Batteries Required? | No | | Color | Original Version | | Customer Reviews | 4.6 4.6 out of 5 stars (2,070) | | Customer reviews | 4.6 4.6 out of 5 stars (2,070) | | Date First Available | 16 March 2013 | | Date First Available | 16 March 2013 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 431 g | | Item model number | 751635700109 | | Item model number | 751635700109 | | Manufacturer | Smooth-On | | Manufacturer | Smooth-On | | Material | Rubber Plastic Wood Silicone | | Number Of Pieces | 1 | | Part number | 751635700109 | | Product Dimensions | 20.83 x 20.32 x 11.43 cm; 430.91 g | | Product Dimensions | 20.83 x 20.32 x 11.43 cm; 430.91 g | | Style | Modern | ## Images ![Universal Mold Release - 14 Fluid Ounce Aerosol Can - Image 1](https://m.media-amazon.com/images/I/71+1rU8vczL.jpg) ## Questions & Answers **Q: why $10 to ship a can?** A: Dear Dan,Universal Mold Release is considered a hazard to ship being as it is an aerosol can. It could also have to do with how far it is shipping. If you go onto our Smooth-On website and go to distributors you may find a distributor in your state or at least close to your state. If you have further questions, please don't hesitate to contact me.Best Regards,Dawn **Q: How do people remove this from the cast part? From what I understand, paint or primer won't stick to the part if the release agent is present.** A: Release agent can easily be cleaned off with a little isopropyl alcohol and a toothbrush. **Q: I have silicon molds and plan to cast with resin to make antler reproductions. Should I spray this inside the silicon mold for easy release of resin?** A: No. This is a silicone-based agent. If you use it on silicone molds, it will glue them together. You’re better off with something like Mann Ease Release. **Q: Is it clear?** A: Yes it is very clear ## Customer Reviews ### ⭐⭐⭐⭐⭐ Effective but a bit pricey​ *by O***N on 24 April 2025* Works well, but it's a bit pricey. Effective for most mold-making tasks, but there are more affordable alternatives available.​ ### ⭐⭐⭐⭐⭐ Definitely Recommend *by K***O on 22 May 2026* Works great getting resin projects out of our Tyvek tape lined molds with very little effort ### ⭐⭐⭐⭐⭐ Great for epoxy release *by G***R on 1 October 2024* 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. ## Frequently Bought Together - Smooth-On Universal™ Mold Release Spray, 14 fl. oz.
