Dow Automotive Systems introduces a revolutionary epoxy formulation for the RTM process. VORAFORACE 7500 is designed to enable carbon fiber composite component assembly and e-coating in the body shop.
RTM is a closed mold process enabling high-fiber reinforcement content in the final composite. VORAFORCE™ 7500 optimizes key processing properties to produce excellent final composite performance and substantial mass reduction compared to metal solutions.
VORAFORCE is ideal for producing large, fiber-reinforced, composite articles integrating glass, carbon
THE VORAFORCE™ 7500 EPOXY SYSTEM IS A GAME-CHANGING RESIN TRANSFER MOLDING SOLUTION, COMBINING EXCELLENT PROCESSING CHARACTERISTICS WITH HIGH THERMAL CAPABILITY FOR BODY-SHOP ASSEMBLY OF STRUCTURAL COMPOSITE COMPONENTS.
Meeting OEM emissions and fuel efficiency requirements is a difficult challenge when working with materials such as steel or aluminum sheet metal. Significant weight reduction is possible with low-density carbon fiber composite components that can function alongside traditional metal components in an efficient hybrid construction.

or aramid fibers that require rapid infusion and cure times for increased build volumes. Depending on process needs (e.g. high-pressure or low-pressure RTM processes, closed mold or open gap injection), the versatility of VORAFORCE 7500 allows easy adjustment of injection and cure profiles as needed, enabling demold times under 3 minutes.

at e-coat oven temperatures and in service. No post-cure operations are required to achieve these properties.
VORAFORCE 7500 drives and attractive ratio of long gel times and short cure times, maximizing production tool output while maintaining excellent processing flexibility, even for large components. Its ultra-low viscosity reduces filling pressure and clamp force, without sacrificing flow length or fiber wetting, even in parts with high fiber content.
VORAFORCE 7500 can enable body-shop assembly of structural composite components.
Dow Automotive systems brings the smart solutions to your composite bonding challenges.
Dow Automotive Systems is also a market leader in adhesive bonding technologies. As the use of lightweight composites and metals has increased, Dow Automotive Systems has developed innovative adhesives that enable much more design flexibility in the use of these materials. For instance, we’ve pioneered a two-component polyurethane bonding system that links dissimilar materials – especially those with low surface energy – allowing the integration of lightweight materials such as aluminum, glass fiber, aramid, carbon fiber and others into vehicle body design and construction.
