Hi-Temp Release Agents

Miller-Stephenson High-Temp Release Agents offers efficient and effective release solutions for molding operations which operate at temperatures exceeding 1562°F / 842°C, such as lights metals or glass molding. Fine particle, hexagonal boron nitride is utilized to impart a low coefficient of friction and temperature stability for these high temperature molding process. Stable in aggressive environments with excellent barrier properties, our boron nitride release system is ideal for all of your high temperature composite, metal, and glass mold requirements. Our High-Temp Release Agents are particularly effective for use in advanced, high temperature composite resins, rubbers / elastomers,  and is also an ideal for die-casting of low melting point metals such as lead. Moreover our specialized release agents are an effective protectant for MAG and MIG welding nozzles while not effecting the quality of the welds. Miller-Stephenson formulations allow the creation of a dry film lubricant that provides the exceptional properties of boron nitride or fluoropolymers in an easy-to-use package that delivers protection of your mold surface,  low electrical conduction, high thermal conduction, prevention of reactions between materials, and superior release.
