Which Epoxy Mold Release Agent is Right For You?

Aerospace is large consumer of epoxies and utilizing an optimal epoxy release agent is critical to achieving their desired needs

Which Epoxy Mold Release Agent is Best For You?

Miller-Stephenson exclusive ReleaSys™ and ShieldSys™ product lines offer superior release coatings that provide ease of application, cleaner molds,  reliable performance.

Miller-Stephenson started distributing epoxy resins, curing agents, fillers, and modifiers in 1955, working closely with our customers to help them develop the desired epoxy formulations that met their specifications.  Soon however we found that high performance formulations aggressively adhered to any surface it was applied it and need a barrier ( mold release agent) to allow good flow-out of the resin into the mold and easy release once cured.  Our technical and engineering teams developed our first, high performance epoxy mold release agent system and Miller-Stephenson has continued from that initial product to pioneer next-generation release coatings that not only allow easy separation of mold, but also provide improved surface quality, zero transfer and paintable surfaces.  Our release systems optimized for epoxy molding typically have the following properties:

  • Ease of application & Rapid Dry Times
  • Zero or Minimal Transfer – No post-molding cleaning or sanding
  • Extended Mold-life and longer intervals between release applications
  • Ultra low-VOC Solvent-based and Zero-VOC Water-based Release Agents
  • Pairs extremely well with our High Performance line of Mold Sealers and Protectors
  • High Temperature and Pressure Stability – will not breakdown or contaminate mold surfaces or parts

Utilization of next-generation release agent chemistry and our vast knowledge of epoxies, curing agents and production methods, allows Miller-Stephenson to provide comprehensive technical support, superior epoxy release agent solutions, and proper training and application instructions to ensure you are successful from the start of a production campaign to the end. Our ReleaSys™ formulations come in both zero-VOC water-based and low-VOC solvent-based formulation variants, as well as convenient aerosol sprays. Another important factor is the use of ultra-high performance mold sealers, which utilized high crosslinking resin technology to tightly bond to your mold surface providing a highly chemical and abrasion resistant sealer coat while greatly enhancing the anti-stick and release properties. Combined with our ReleaSys release agent coatings is potent, efficient, cost-effective upgrade to any epoxy production process.  Below you will find the most highly recommended products for the epoxy mold release:

Miller-Stephenson Exclusive Epoxy Molds Release Agents

ReleaSys™ 7200 – Ultra-premium, solvent based hybrid-wax epoxy release system, “wipe on, leave on” coating (no buffing required), does not effect painting, bonding, or gluing, exceptional release of epoxy and composite formulations.

ReleaSys™ 8000 – High Performance, ultra-thin release system, provides high release and lubricity ideal for highly aggressive and high tack epoxy mixtures. For aerosol we recommend the ReleaSys™ 89S

ReleaSys™ EP5 – Miller-Stephenson exclusive fluoropolymer/PTFE coating, effective on nearly all epoxy / composite formulations.  Ultra-fast dry times and compatible with all most surfaces.  Molded item requires no post molding cleaning.

ReleaSys™ DFX – Aerosol version of ReleaSys™ EP5, designed to provide uniform, thin coatings.  Ideal for complex geometries or when the convenience of aerosol spray is needed

ReleaSys™ 7200W – Water-based, Zero-VOC version of the ReleaSys™ 7200, highly effective epoxy release agent that is easy to apply, cost-effective, and compatible up to 800° F curing temperatures

ReleaSys™ 8800 – Water-based, Zero-VOC high performance coating, offers superior release ease, multiple releases from a single application, and is ideal for simple and complex mold geometries.  Improves flow-out and levelling.

ReleaSys™ 8200 – Water-based release system utilizing exclusive small particle PTFE, so provide superior release without effecting any post-molding operations. No post-molding cleaning is required.

ReleaSys™ MOLD SEALER – High crosslinking and durable synthetic resin mold sealer, binds tightly to mold surfaces sealing micro-porosity and curing to a robust, ultra-thin anti-stick coating.  Greatly enhances the consistency and performance of any of our ReleaSys™ epoxy mold release agents

ReleaSys™ Epoxy Release Agents: Advanced Chemistry, Cost-Effective, Efficient – A potent combination

Our customer have found number benefits when they have transitioned to our ReleaSys Epoxy product line: Benefits include:

  • Achieved significantly more mold cycles per shift and higher efficiency production campaigns
  • More molding cycles can be attained per working shift due to efficient release ease and the need to apply the release system less frequently
  • Low mold release application levels resulting in a cleaner molds and working areas
  • Significant reductions in scrap rates related to sticking issues or poor surface quality
  • Molds can remain in production for extended periods of time
  • Complicated parts can be made in a trouble-free manner
  • Molded parts retain consistent cosmetic appearance for longer with significant lower “re-works”
  • Molded parts can be post-painted or glued with little or no surface preparation
