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.
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.
