Trelleborg Completes Portfolio of Tool and Mold Manufacture Products With New Release Agent

The easily applied solution ensures a superior finish and allows Trelleborg to offer a complete suite of products for tool and mold manufacture. As such, customers can now order all tooling board, sealing pastes and release agents from a single manufacturer.

Chris Mellings, Business Group Manager for Trelleborg’s Advanced Engineering Materials (AEM) operation, says: “When someone wants to produce a composite component they need a specific tool. We mold their desired shape from our epoxy tooling block but the inherent nature of the block makes it porous, and so it must be sealed to stop any ingress. The seal isn’t inherently a release surface, meaning that an additional release agent is required.


ER950
“Our new ER950 enables the mold or component to come away from the tool without sticking and also allows multiple manufacturing cycles without the need for re-application.”

Trelleborg’s high gloss release agent can be used with all composite media – pre-pregs, resin transfer mold and infusion processes - so customers can now purchase a complete suite of products from one manufacturer. The ER950 is a low odor and non-chlorinated system, which is applied using a simple wipe-on technique.

EP661
In addition to the ER950, Trelleborg will also showcase its EP661 high temperature adhesive at the show. Most tooling blocks only allow use up to +150°C and below +125°C, however Trelleborg’s new tooling blocks can mold components at temperatures of up to +230°C. The EP661 is a two component, low viscosity, epoxy adhesive system which be used for many diverse bonding applications but is most suitable as a thin bond line adhesive for blocking up Trelleborg epoxy boards. The adhesive system gels at room temperature, but requires a post cure to achieve maximum properties.

JEC Europe is the leading platform for the global composites industry and this year, the show celebrates its 50th anniversary. Visitors to the world’s largest three-day composites event based in Paris next month, can enjoy valuable networking platforms and knowledge-sharing conferences.
