Antimicrobial Coatings Through Silane Functionalization

Non-Leaching Biocidal Mechanism

Quaternary ammonium silanes (QAS) chemically graft biocidal groups onto coating surfaces:

Hydrolytic stability maintains >95% efficacy after 50 wash cycles

Cationic charges disrupt microbial cell membranes

Antimicrobial Efficacy

Pathogen Reduction Rate (2h)

MRSA 99.99%

E. coli O157:H7 99.95%

Candida albicans 99.8%

Healthcare Implementation

Cleveland Clinic reported 68% decrease in surface-transmitted infections after applying QAS-epoxy coatings in ICU units.
