Exel’s fiberglass and carbon fiber profiles contain an anti-viral additive that is blended into the composites resin during the manufacturing process. The additive permeates the composite and ensures consistent distribution throughout the resin, providing virus protection throughout the material’s lifecycle.

FREMONT, CA : Exel Composites, a global composites manufacturer, has unveiled its anti-viral Protector solution, which has been shown to reduce human Coronavirus strains’ viral load. As compared to untreated composites, the findings showed a 99.44 percent reduction in viral load after one hour and a 99.99 percent reduction after 24 hours.

“The COVID-19 pandemic has highlighted the importance of anti-viral solutions and precautions that must be taken with all viruses,” said Kim Sjödahl, SVP Technology, and R&D, Exel Composites. “Hand sanitizers and disinfectant products have now blended into our daily lives. However, manufacturing anti-viral surface materials can easily heighten anti-viral protection in a range of sectors. Our Protector composites reduce the viral load and provide additional protection that can be used in areas where there are high levels of bacteria accumulation. This includes handrails on public transport, and equipment handles in cleaning and maintenance applications.”

Exel’s fiberglass and carbon fiber profiles contain an anti-viral additive that is blended into the composites resin during the manufacturing process. The additive permeates the composite and ensures consistent distribution throughout the resin, providing virus protection throughout the material’s lifecycle.

“A significant benefit of our anti-viral solution is that the additive acts as a built-in layer of defense within the material,” continued Sjödahl. “The additive working in the resin ensures durability and reliability of the anti-viral protection, as its effectiveness does not decline over time—a common disadvantage of alternative surface treatments such as sprays, coatings and foils. Even if the composite is scratched, the anti-viral protection remains unaffected.”

Exel sent material samples to bacteriology, virology, and industrial microbiology-focused independent third-party laboratory. The samples were tested following ISO 21702:2019—Anti-viral activity measurement on plastics and other non-porous surfaces. On Exel’s composite Protector samples, the 229E Coronavirus strain was found to be substantially reduced.

“Our solution does not affect the pigmentation, texture, mechanical or structural properties of the material”, added Sjödahl. “This means it can be applied to any composite product for any industry. “Exel Protector is a remarkable step forwards in our product offering, demonstrating a significant reduction in the spread of contagious diseases. With this, we hope to help improve the safety of people across the globe.”

Exel Composites has a long history of developing composite solutions to meet a wide range of industry needs, from turbine blades to window frames. Exel’s Protector solution can be integrated into the production of any composite profile they create.
