Known for its global design and construction of UV and LED technology, IST America (Shorewood, Ill., U.S.), part of the IST Metz Group, is sharing innovations in its light curing platforms for polymer matrices in composite component production. IST says that the state-of-the-art advancements save significant time and energy while maintaining high quality.

UV curing is a versatile solution for various production processes, including wet layup techniques, vacuum infusion with UV-transparent membranes, filament winding, prepreg processes and continuous flat processes. Unlike traditional thermal curing methods, IST America points out, UV curing delivers optimal results in less than a minute as opposed to hours, cutting cycle time and energy consumption. This also amplifies an industrial process’ sustainability benefits, as it requires only one tool, thus reducing carbon footprint.

A standout benefits of UV formulations is their styrene-free composition. The 1K solutions feature an extended pot life of several months, eliminating the need for complex storage. Additionally, they contain no volatile organic compounds (VOCs), making them environmentally friendly and compliant with strict regulations.

IST America ensures optimal curing results by leveraging various radiation sources and light profiles tailored to specific applications and curing strategies. While the thickness of laminates is limited to approximately one inch for efficient UV application, multi-ayer buildups can be considered, expanding the possibilities for composite designs and providing an alternative for structural composites.

The market offers formulations that facilitate the curing of fiberglass and carbon fiber. These advancements are said to be enhanced by IST America’s expertise in designing and installing customized light sources.
