Semi-Permanent Release Agents - ABOUT

ReleaSys™ is Miller-Stephenson’s most advanced, semi-permanent release agents which maximizes releases per application and minimizes mold fouling and transfer. Our release agent forms a chemical bond to the mold surface which results in exceptional surface adhesion, durability, and application efficiency. All variants of the ReleaSys™ Series will deliver higher productivity, lower rejection rates, and higher quality products even in the most demanding applications. We offer various slip-levels and have specialized formulations for differing polymer types and molding processes ( ie: injection, transfer, compression).  Miller-Stephenson has developed ReleaSys™ semi-permanent release agents with formulations that are applicable for virtually all types of composites, elastomers, urethanes and organic polymers.

Our customers can expect higher productivity and profitability through reduced downtime, increased acceptance rates and improved part quality when switching to Miller-Stephenson’s ReleaSys line. Our formulations are 100% nonflammable, low odor and are offered in either water or solvent-based carriers. These products come as either aerosol formulations for convenient, uniform application or as economical bulk formulations.
