A History of Helping Composite Molders

Composites molding encompasses the manufacture of a vast number of products in a wide variety of industries including, but not limited to:

  • Marine
  • Land Transportation
  • Aerospace
  • Motorsport
  • Wind Energy
  • Construction

To manufacture products for all of these applications molders can employ a wide variety of processes. Each of these processes have some common, and some specific, attributes that need to be provided by the mold release agents to ensure that the parts being molded will be released properly, cleanly, efficiently and without damage either to the part or the mold.

Chem-Trend started its history of helping molders of composite components in the late ‘70s/early ‘80s, working side-by-side with molders of advanced composites. Then, in the mid ‘80s we came out with a line of products under the RPM (Reinforced Polyester Molding) name as we further expanded helping people in the Fiber Reinforced Plastic (FRP) part of the industry. In 1998 we augmented all of the knowledge and experience we gained in those areas by acquiring the company that developed the globally respected Chemlease® line of release products for the composites industry. That action helped us expand our expertise, technology and product range to further help molders around the world address the challenges of molding composite parts.

Mold Release Agent Options for Molding of Composite Materials

When looking to release composite parts there are multiple issues to consider, such as:

  • Slip Level
  • Post Molding Processes
  • Size/Weight of the Molded Item
  • Complexity/Geometry of the Shape of the Molded Item
  • Manufacturing and Environment Issues/Regulations
  • Surface Appearance/Finish Quality of the Molded Item

The release agent/release system chosen can have a positive or negative impact relating to all of these issues. Additionally, the cost of the tooling in composite molding is often quite high. Therefore, you want to choose your release agent/release system carefully to protect your investment and get maximum life and productivity out of your tools.

Our roughly three decades of experience developing solutions for composite molding problems has led us to formulate an extensive range of both Semi-Permanent and Conventional Chemlease® brand external release agents. We have also developed specialized internal release agents for particular applications in the molding of composite pieces. All of our products for composite applications have been created to improve efficiency, lower scrap and protect molds.

Common Questions:

  • Can I use the same release for all of my parts, regardless of whether they are gel-coated or not?

    While some manufacturers may choose to use one semi-permanent release for all their needs, we believe that gel coated and non-gel coated applications should be handled differently, as should male and female tools. Typical non-gel coated applications such as stringers, require a slicker release agent than a gel-coated tool.
