Zusammenfassung:	An aqueous antimicrobial coating composition capable of forming an antimicrobial coating on a surface comprises at least two organosilanes, each of the at least two organosilanes having a structure, R-Si(OR′)3 wherein R=-(CH2)3-Y; Y=+-N(CH3)2(C18H37)X−; +-N(CH3)2(C14H29)X−; +-N(C10H21)2(CH3)X−; -Cl or -NH2; X−=halide, sulfate, nitrate, phosphate, carbonate, organic sulfonate, organic carbonate, BF4−, or ClO4−; and R′=H, methyl or ethyl, or a C3-C6 straight-chained, branched or cyclic alkyl group, with the proviso that the organosilane R-Si(OR′)3 having the C3-C6 straight-chained, branched or cyclic alkyl group hydrolyzes in the aqueous antimicrobial coating composition to R-Si(OH)3.
