Quaternary Ammonium Antimicrobial Finish for Textile
CAS Number: 65229-15-4
A silane-based quaternary ammonium compound providing durable antimicrobial finish on cotton, polyester, and blended textiles. Unlike leaching-type antimicrobials, it covalently bonds to fiber surfaces via silanol groups, creating a non-migrating biostatic layer. Effective against Staphylococcus aureus, E. coli, and various molds, meeting ISO 20743 and AATCC 100 testing standards.
