Release Agents | Semi-Permanent Mold Release Agents | PTFE Mold Release Agents

Miller-Stephenson’s mold release agents are backed by over 50 years of research and development and are relied upon by global industries to ensure the efficient, cost-effective, and high-quality release of their molded parts. By pioneering release agent solutions for many of the largest manufacturing organizations, Miller-Stephenson understands what it takes to release the most complex materials in the most demanding molding applications. We have developed specialized release agent formulations for manufacturing operations such as composite/FRP moldingelastomer and rubber moldingpolyurethane and extrusion PUmandrel lay-ups, vacuum bag molding, rotational, compression, and injection molding, etc. Our mold release agents are optimized to maximize throughput and efficiency of the critical parts you mold; from airplane stow bins to O-rings, carbon-fiber bike frames to tires, Miller-Stephenson has a solution for your molding operation. Moreover, all of our formulations are 100% non-flammable, minimal odor, and low to no VOC and are available as eco-friendly water-based formulations. Miller-Stephenson specializes in providing water-based release agents which offer superior performance, safety and greatly reduced environmental impact. Utilizing the most technological advanced mold release systems, Miller-Stephenson will help molders maximize releases per application, throughput and minimize defects and scrap rates,  For more information about which mold release agent is right for you to go to our guide or for guidance on proper mold preparation and release agent application.

Why are Release Agents such a critical part of a molding companies operations? Mold release coatings provide the critical barrier between a molding surface and the substrate, facilitating separation of the cured part from the mold. Without such a barrier in place, the substrate would become fused to the mold surface, resulting in difficult clean-up and dramatic loss in production efficiency. Even when a mold release agent is used, factors such as irregular applications or improper release agent choice will have a dramatic effect on the quality and consistency of your finished product. It is therefore critical that engineers understand what types of mold release agent are available and which variant would compliment their production method.  There are numerous release agents chemistries, Miller-Stephenson focuses on the development and refinement of the most robust and advanced polymers, specifically focusing on PTFE (polytetrafluoroethylene), and reactive polysiloxanes.

Critical performance criteria for release agents to meet is the following:

  • Surface adhesion and durability
  • Ability to form a thin-film
  • Sufficient surface slip & Ease of release
  • Chemical inertness to the molding process
  • Numerous releases per application
  • Minimal or No Transfer

Release agents types and individual products within those types, vary significantly in regard to slip, application methods, production efficiency, and cost. For that reason, manufacturers who invest time researching and testing release agents will see a return on that investment.  Sacrificial (typically waxes and silicone oils) and PVA release agents are the lowest cost materials, offering adequate slip and chemical inertness.  Unfortunately, these sacrificial agents must be re-applied after each molding cycle and will contaminate he molded part.  This results in time-consuming cleaning of the molded part and dramatic limitations in productivity. Interestingly, while the initial cost may be lower for the sacrificial and PVA release agents, the overall cost is substantially more as one can expect more releases per application and little to no post-operation cleaning with PTFE and reactive polysiloxane resins, like ReleaSys™. ReleaSys, is our newest and most robust release agent product line.  Utilization of cutting-edge, thin-film polymer technology combined with our dedication to environmentally friendly water-based formulations, Miller-Stephenson has developed the most advanced release agent coatings that will outperform every other release agent, guaranteed!. ReleaSys has proven itself to be highest performing and most cost-effective release agent system in numerous head-to-head comparisons against other industry-standard coatings.  Combining ReleaSys release agents with our advanced ShieldSys Mold Sealer coatings, only further enhances the value-proportion, efficiency, durability, and number of releases per application.
