Hybrid mold release agent offers paste wax simplicity with semipermanent performance

Chem-Trend (Howell, Mich., U.S.) introduces a solution for composites manufacturers looking to move away from the labor-intensive demands of traditional paste wax but aren’t ready or able to make the jump to solvent-based semipermanent mold release systems.

Chem-Trend’s 2775W is a one-part water-based hybrid release agent that delivers multiple releases per application in a nonflammable, VOC-free and PFAS-free formulation. Developed in response to direct feedback from customers, this innovation provides a Class A surface finish with less effort and downtime compared to paste waxes.

The release agent mimics the familiar application process of paste wax, making it ideal for operations not yet equipped to convert to solvent-based systems. It can be sprayed or hand-applied with a clean cotton cloth, then left to flash off into a light haze before a simple buff by hand — no mechanical buffing tools or long cure times required.

Once in production, Chem-Trend reports that the hybrid release can offer up to four times more releases between touch-up coats than conventional paste wax, providing gains in efficiency and consistency. At the same time, it minimizes build-up on the mold surface, helping maintain surface quality over time.

Attendees are able to see this hybrid release agent in action and explore additional innovations, including silicone-free release solutions and next-generation high-build primers designed to improve surface quality and process throughput.
