AERO is committed to saving lives amidst the SARS-CoV-2 (COVID-19, novel coronavirus) pandemic
AERO Clear 420 Launched to Help Combat COVID-19 and Assist Healthcare Workers

The SARS-CoV-2 (COVID-19) virus illuminated the urgent need for healthcare worker personal protective equipment (PPE). Yet, the current state of the art for surgical face shields limits the function of the PPE, and subsequently, the effectiveness of the healthcare worker.

Polycarbonate and polyester (PET) have very low resistance to abrasion. In healthcare, permanent polycarbonate and disposable PET shields are therefore limiting due scratches forming from continued usage within the healthcare provider’s field of view. Further, continuous necessary washing further ablates the surface of the shield causing micro-scratches where bacteria and other pathogens can emerge or embed themselves. This poses an additional environmental hazard and can inhibit infection prevention.

AERO™ Sustainable Paint Technology seeks to aid the effectiveness of healthcare workers through the deployment of a self-healing, flexible shield cover for washable face shields.

Product Description

AERO™ Sustainable Paint Technology was originally developed for the aerospace/defense industry as a durable, lightweight evolution to paint and clear coatings. The technology was then perfected in the extreme environments of motorsport and is available today for multiple applications across numerous industries.

Within the medical industry, the same ultra-durable, self-healing clear film technology can be utilized as a both a permanent film cover for washable polycarbonate face shields, as well as a temporary disposable standalone face shield as AERO Clear Shield. AERO Clear 420’s core technology is based on the confluence of advanced chemistry and materials science, where scientists were able to engineer superior performance into the chemical structure, molecule by molecule.

The resulting polyurethane-based AERO Clear 420 product is a 0.4 mm self-healing, optically clear, flexible, comfortable, and washable shield film that will not scratch over continued usage or maintenance. AERO Clear 420 can withstand numerous washes with antimicrobial disinfectants and detergents, and is inherently non-porous, thereby inhibiting pathogens from growing or dwelling on the face shield.

AERO Clear 420 is designed as a flexible shield to allow for improved wear comfort. The design is compatible with other PPE, and allows the healthcare worker unencumbered movement. Further, the flexible design will not be jarred loose by contact with patients, workers, and/or equipment during delivery of care.
