The R&D team of Ontario-based Tier 1 automotive interiors company CpK has developed a patent-pending additive, Forti-VI, that reportedly can kill 99.9999% of SARS-CoV-2 virus on material surfaces in less than 60 minutes. The company has three facilities in Ontario and is vertically integrated with a plastics compounding plant within that group. Explains head of R&D Dr. Gregory Farrar,  “We produce our own flexible PVCs, TPUs, and TPOs, and about 50% of all R&D activities are dedicated to developing novel materials and carbon-fiber composites.”

The company has not publicly disclosed the chemistry of the additive, as the patent process takes about 16 months to complete. However, the company will sell the additive—a first such commercial venture for CpK. “We can supply the additive at any time,” says Farrar. “Because we cannot control the manufacturing of other companies, they will also require regulatory approval for their end products.”

CpK's antiviral additive for use in auto interiors.

FCA’s “Healthy Cabin Initiative” challenges its suppliers to find ways to reduce risk of coming into contact with the COVID-19 virus in automobile cabins.

NO FREE RIDE FOR COVID-19

 

To date, CpK has produced pelletized masterbatches for testing injection grade resins such as PP and PC/ABS. “Our core business is to produce our own flexible polymers so that remains are primary short-term focus. We have the R&D capability of doing the masterbatch work but lack the scale-up equipment so our preference is to provide the additive to the market in powder form. Our plan is to supply this to many potential customers, including competitors that also make interior automotive trim components. We only make instrument panels, doors, and consoles so for a car to truly contain an anti-viral cabin, we need to work with competitors.”

CpK  developed the anti-viral plastics project in response to the coronavirus global pandemic and a call-to-action from Fiat Chrysler Automobiles (FCA). Knowing that customers would be concerned about the interior safety of their vehicles, FCA created the “Healthy Cabin Initiative,” challenging its suppliers to find ways to reduce the risk of coming into contact with the COVID-19 virus in automobile cabins. CpK was able to successfully invent, test, and apply for a patent within 90 days of the project kickoff.  CpK’s R&D team was tasked to create material for car interiors that showed anti-viral activity.

The CpK team invented cast skin materials for the Dodge Challenger and Charger. Explains Farrar, “This was no simple task, but our team had experience inventing novel materials in the past. Not only did CpK have to discover which materials could actively attack the DNA of coronavirus, we also had to navigate the stringent and timely quality and testing requirements for new auto-interior materials. A single test such as UV resistance and heat aging can typically take up to 21 days to complete, but we were able to have prototype parts sent to FCA within a month of kicking off the project.”

CpK and a Canadian University had to develop their own biosafety lab to test this new additive.

One of the challenges the team faced was anti-viral testing. Most Canadian labs don’t have the infrastructure to handle Biosafety Level 3 viral pathogens like SARS-CoV-2. CpK was able to contract the ImPaKT Facility at Western University’s Schulich School of Medicine & Dentistry in London, Ont., to collaborate and perform testing. The ImPaKT Facility is a one-of-a-kind CL2+/CL3 facility with advanced in vivo imaging capabilities, which allow researchers and industry to develop tools and methods to better understand the progression of infectious diseases, identify effective antimicrobial agents, develop diagnostic reagents to characterize hidden reservoirs of pathogens, and achieve early and accurate detection of infections. CpK is uniquely structured to meet a challenge like this as it has the ability to develop, test, and manufacture raw materials; use those raw materials for injection molding and foam-in-place instrument panels, doors, and consoles; then do final assembly and ship the finished product to the customer.
 

Could Protect Mass Transit, Medical Devices & Flooring

According to Farrar, the additive has many applications outside of automotive. “Our patent has 80 claims, with the majority of the focus outside of automotive. It could be used for public transit (buses, subways, planes, etc.), commercial spaces (flooring, door handles, etc), and in medical devices.” The company is undertaking the approval process from Canada’s PMRA and the U.S. EPA for use in auto-interior components. Says Farrar, “This ensures that we have enough data to support our product claims. Given that we have been testing on the SARS-CoV-2 strain directly, we don’t feel that there will be any issue with our data. Most labs do not have this virus strain, so the lab we chose was strategic.”
