The thermogravimetric analysis (TGA) can be used to compare and demonstrate the thermal stability of the material in service. In a recent study, we have compared a solidified competing commercial antimicrobial coating in an inert atmosphere thermogravimetric analysis.
In a work accomplished with pre-painted panels top-coated with INVESIL it was demonstrated by the US NAVY research lab that chemicals equivalent to biologically active agents cannot penetrate through INVESIL coated surface.
A sudden COVID-19 crisis has significantly affected the air travel and created an awareness on protection from pathogens in public places. The rise of new pathogens and threat of possible future pandemic situations has further fueled the market of antimicrobial coatings in the aviation sector.
The INVESIL product is owned and globally Patented by Flora Coatings, Phoenix. Several patents and Trademark have been awarded to this technology. INVESIL is considered world’s first commercial broad spectrum antimicrobial coating..
According to a survey conducted by IHS Markit,, about 25 percent of people did not want to use rideshare post-COVID-19. In comparison, 80 percent expect the rideshare vehicle to be equipped with decontaminators.
Several companies are claiming that their coatings could last for months. However, no such data has been generated or proof available in support of their claims. Specially, if coating is less than 1 micron, it is difficult to believe those claims. We at Flora Coatings have compared a competitive commercial product with INVESIL. The commercial product was applied as received and tested using Taber Abrasion as per ASTM.
Recent studies have identified the broad-spectrum antiviral properties of silver nanoparticles (AgNPs) against respiratory pathogens, such as adenovirus, parainfluenza, and influenza. AgNPs achieve this by attaching to viral glycoproteins, blocking entry into the host cell.
INVESIL was spray coated over silicone rubber gloves and displayed exceptionally good adhesion. Coated gloves after drying can be stretched as INVESIL is an adequately flexible.
In a recent work accomplished through an ASTM verified lab it was demonstrated that INVESIL after 1000 hours of aggressive Xenon weathering exposure as per ASTM G115, showed no changes in surface appearance. It clearly demonstrates that INVESIL chemistry remains intact after long aggressive weathering. The number of exposure hours can be indirectly correlated to the service life of the coating. In this case, INVESIL shows more than one year of service life in an aggressive environmental condition.
