RTM & Infusion Resins

When producing composites of the future using RTM and Vacuum Infusion methods, the right resin selection is critical. We offer two specialized solutions that are ideal for producing parts with smooth and aesthetically pleasing surfaces on both sides.

KEY FEATURES

Seamless and homogeneous composite structure
Near-zero styrene emissions
Large-scale production capacity
High repeatability and precision

RTM (Resin Transfer Molding)

Pressurized resin injection method with closed mold system. Ideal for high precision and repeatable production.

Closed mold system
Pressurized resin injection
Vacuum assisted operation
