SALT LAKE CITY, June 30, 2021 (GLOBE NEWSWIRE) -- SINTX Technologies, Inc. (www.sintx.com) (NASDAQ: SINT) (SINTX or the Company), an original equipment manufacturer of silicon nitride ceramic for medical and non-medical applications, announced today it has moved into the next phase of its relationship with O2TODAY and sold the first shipment of FleX SN-AP antipathogenic silicon nitride powder to O2TODAY for integration into a proprietary line of masks and filters.

O2TODAY announced on its website today that it is taking limited pre-orders for masks and mask filters integrated with SINTXs antipathogenic powder, said Dr. Sonny Bal, President and CEO at SINTX Technologies. We share the excitement at this development, and weve appreciated the opportunity to collaborate on the development of O2TODAYs products over the past year.

SINTX is the supplier of FleX SN-AP antipathogenic silicon nitride powder to O2TODAY. The powder is used to make O2TODAYs face masks and mask filters which were developed during a collaboration entered by the two companies in the midst of the 2020 COVID-19 pandemic. That collaboration has led to several milestones including a 2-year Technology License Agreement with a fee for the exclusive use of SINTXs technology in face masks and mask filters, a commercial agreement on silicon nitride sales, and royalties from product sales.

SINTX continues to work with other partners to develop products with its FleX SN-AP powder. SINTXs FleX SN-AP can rapidly inactivate a wide range of bacteria, molds, and viruses, including SARS-CoV-2, Influenza A, and H1N1. FleX SN-AP can be incorporated into many consumer products and touch surfaces, making them resistant to disease-causing microbes. The SINTX R&D team has the knowledge and expertise to create niche applications with FleX SN-AP technology to enhance your companys products.

O2TODAYs masks and filters with silicon nitride are expected to become available for limited pre-orders starting on July 6, 2021. For more information please visit https://o2today.com/products/sinpro
