Composite Mold Release Agents – ReleaSys™

Miller-Stephenson Composite mold release agents are backed by over 40 years of technical experience and are trusted to deliver the most consistent release of composite material in the industry. Our formulations are uniquely tailored to yield unmatched utility and efficient for the robust and constantly evolving composite industry. These wax- and silicone-free release agents crosslink to create a low surface energy film which exhibits high slip, superior durability, chemical resistance, and thermally stable. Large and small manufacturers can expect higher productivity and profitability through reduced downtime, increased acceptance rates and improved part quality when switching to Miller-Stephenson’s ReleaSys semi-permanent line or PTFE Dry Flim Release Agents. With our composite mold release agents operators will see minimal transfer to molded components, low clogging, easy application and the highest number of releases possible per application guaranteed. As a leader in the development of water-based products, Miller-Stephenson offers environmentally conscious technology for composite molders who require the same, uncompromised high levels of quality and performance as found in traditional solvent-based products. Benefits of utilizing our mold release agents include:

  • Low or No volatile organic compounds (VOC)
  • Minimal odor; 100% Non-flammable formulations
  • Semi-permanent mold release bonds to mold surface for consistent release
  • Higher productivity; Increased cost-effectiveness
  • Low rejection rate; Consistent part quality
