Details & Benefits


Reduced Buildup and Mold Protection

Our composite release agents are designed to provide reliable release characteristics without building up on the mold surface. Reduced buildup will cut down on cleaning time and frequency as well as reduce rejection rates due to poor surface finish or failed release. Reducing the frequency of cleaning operations also saves molds and tools from physical and chemical abrasion over time extending their effective lifespan.


Supported Materials

Reinforcement materials: carbon fiber, aramids, glass, metals, boron, woods, ceramics, and others
Matrices: epoxy, phenolics, polyester, vinyl esters, aromatics, and others

Supported Processes

Open Molding (Filament winding, lay-up)

Closed Molding (Autoclave, vacuum bagging, compression molding, centrifugal, RTM)

Solid Surface Molding/ Engineered Stone


  • More control over your process
  • Multiple releases per application
  • Reduced buildup on molds and tooling
  • Improved efficiency of your molding operation
  • Superior surface finish quality
