About Rexco: Decades of Expertise in Mold Release Chemistry

When it comes to mold release technology for the composites industry, few names carry as much weight as Rexco. Founded in 1953, Rexco has spent more than seven decades refining a focused, highly effective lineup of mold release agents, parting films, and mold care products trusted by manufacturers around the world. What began as a small regional operation has grown into a globally recognized supplier, with export sales reaching over forty countries and a primary manufacturing presence on both coasts of the United States.

Rexco’s reputation is built on a simple but powerful philosophy: produce quality products that work reliably, at a price that makes sense for production environments. As a family-owned company now in its third generation of leadership, that founding commitment has never wavered. The result is a product portfolio that professionals in fiberglass fabrication, cultured marble production, cast polymer manufacturing, and polymer concrete work have come to depend on day in and day out.

Trusted Brand Names, Proven Formulas

Rexco’s product lineup is organized under three well-known brand families: PARTALL®, MARBALEASE®, and FORMULA FIVE®. Each line addresses a specific segment of the mold release and mold care workflow. PARTALL® products include the iconic PVA parting films and paste waxes that have become industry standards for protecting mold surfaces and ensuring clean part release. MARBALEASE® is purpose-built for cultured marble and cast polymer applications, while FORMULA FIVE® covers mold cleaning and buffing compound solutions that keep mold surfaces in peak condition between production cycles.

A standout in the Rexco catalog is their leadership in polyvinyl alcohol (PVA) parting film technology. Rexco is recognized as the leading North American manufacturer of PVA film-forming barrier solutions for thermoset composites—a category where performance and consistency are non-negotiable. Their PVA films are solvent resistant yet water soluble, and the lineup includes both traditional alcohol-based formulas for fast drying and newer environmentally friendly, non-hazardous options.
