College campus uses antimicrobial surface coating from AggreCoat Silver with Polygiene BioMaster

Considering the ongoing pandemic, the College of the Marshall Islands (CMI) has acquired an antimicrobial surface coating and begun applying this throughout the campus.

The coating, AggreCoat Silver (, has been independently tested and shown to be effective at reducing microbial levels on a surface. 

When tested to ISO 21702:2019, it showed a reduction in SARS-CoV-2 on the surface of >82% after 6 hours and >95% after 24 hours when compared to a control. (SARS-CoV-2 is the virus that causes Covid-19).

Biomaster silver ion technology disrupts the cell wall, blocks energy production, and stops DNA replication, to inhibit the growth of bacteria on a surface. Bacteria tested include E. coli, Listeria and Salmonella.

Robert D. Friedman, President of AggreBind Inc., explains: “AggreCoat Silver was initially developed in 2015 to meet microbial and bacterial challenges. As the world changed, AggreCoat Silver advanced its technology to address today’s viral threats of SARS-CoV-2. We consider it the trifecta of coatings, where hygiene is important. It is not a replacement for good housekeeping and good hygiene; AggreCoat Silver gives you that additional layer of product protection.”        

Nick Brosnan, Global Marketing Manager at Polygiene adds: “As we return to classrooms, education providers are looking at existing cleaning protocols with hygiene being of paramount importance for students, educators and parents alike. AggreCoat Silver is a long-lasting, clear, hard, surface coating that inhibits microbial growth on protected surfaces. The coating is easily applied, and long-lasting. CMI and its community are able to offer additional product protection within it environments with AggreCoat Silver.”
