CAPLINQ's Chemlinq MRE-C909 Mold Release is a carnauba wax based, sprayable aerosol mold release agent. It contains no silicones or oils and is therefore not only compatible but complementary to epoxy molding compound and other thermoset plastic molding.
Chemlinq MRE-C909 is a fully REACH and RoHS compliant carnauba wax mold release aerosol spray and does not contain trichloroethane (CAS: 71-55-6) or dichloromethane (CAS: 75-09-02). It is designed for mold release of epoxy molding compounds and was specifically formulated as an alternative to MJ Gordon Permasil #909C after MJ Gordon discontinued the production of this product. MRE-C909 is literally the 9th iteration, and serves as a reminder of the 8 previous unsuccessful formulation attempts before finally formulating MRE-C909.
In order to have the best results during the production process, a thin, uniform thickness of MRE-C909 should be sprayed on the mold. The release agent has no build-up on the mold and should show a shiny surface when properly applied.
There is no alternative for this product, but rather this product is an alternative to MJ Gordon Permasil #909C

Carnauba wax itself is nothing new. It is a natural wax derived from the a palm tree native to the northeastern Brazil. It is used in a wide variety of applications including automotive waxes, shoe polishes, dental floss coatings, and paper coatings. More importantly, it is used in the production of epoxy molding compounds themselves as the mold release agent.
Carnauba wax is the same natural mold release wax used in the manufacture of semiconductor epoxy molding compounds
There is no silicone, Teflon or oil in the MRE-C909 formulation. While Teflon and silicone may be well-suited for the release of rubber molds or to coat anti-stick surfaces, they rarely have a place when working liquid epoxy, epoxy molding compounds (EMC) and other thermoset plastic types. Most semiconductor manufacturers know this of course, and use chunks of carnauba wax to break in new epoxy molds or to release the plunger when it sticks. Carnauba wax is compatible with epoxies and generally enhances its properties along with those of most other engineering plastics.
Chemlinq MRE-C909 does not contain any chlorofluorocarbon and ozone-depleting substances. It also does not contain trichloroethane CAS No: 71-55-6 or dichloromethane CAS No: 75-09-2, making the solvent and propellant used physiologically safe as well as both REACH and RoHS compliant.
Chemlinq MRE-C909 is a non-silicone mold release agent developed specifically for both transfer molding and compression molding where thermoset plastics such as epoxies, phenolics, and melamines are used. MRE-C909 is suitable for epoxy mold compound applications which require only a thin, uniform layer of mold release for best results. Due to its dryness, MRE-C909 provides the perfect balance of release and rustproofing for the mold without leaving a greasy layer on the molded part after molding.
Chemlinq MRE-C909 is a proven alternative to MJ Gordon #909C. CAPLINQ worked very hard developing a carnauba wax based mold release spray that, unlike MJ Gordon’s #909C, is fully REACH and RoHS compliant. With final phase of REACH being introduced in 2018, it was imperative that our European clients found and qualified a carnauba was mold release spray that they could use after REACH was fully implemented.
Just like MJ Gordon’s #909C it’s an aerosolized solution of carnauba wax suspended in a solvent and using a propellant. Unlike the MJ Gordon #909C, both the solvent and the propellant are REACH and RoHS compliant. As a carnauba wax based released agent it has excellent compatibility and great release properties. However, a small downside of using a REACH and RoHS compliant solvent and propellant is that it is unfortunately flammable.
Four (4) “non-silicone” candidates were evaluated alongside the benchmark MJ Gordon #909C
Semiconductor Grade Epoxy Molding Compound was molded with 5 different “non-silicone” based release agents:
Many mold release types are INCOMPATIBLE with Epoxy Molding Compound (EMC)
Results with other mold release agents:
These bars were molded after treating the molds with other non-silicone candidates
Mold results with MRE-C909 were identical as those with MJ Gordon #909C
Results with CAPLINQ Chemlinq™ MRE-C909
These bars were molded after treating the molds with MRE-C909 and Gordon’s Carnauba spray release.
Of all the carnauba wax candidates tested, only the MRE-C909 gave the same excellent results as the MJ Gordon #909C
There was a clear difference between other "non-silicone" carnauba wax epoxy mold compound release products and the MRE-C909. Only the MRE-C909 worked like a true alternative to the MJ Gordon Persmasil #909C
