Abstract
A method of manufacturing an aircraft metallic faucet with an anti-microbial coating may comprise: disposing the aircraft metallic faucet in a piranha solution; washing the aircraft metallic faucet; and coating a surface of the aircraft metallic faucet with a Si-Quat based coating. A method of manufacturing an aircraft metallic faucet with a hybrid anti-microbial coating with cross-linkers may comprise: disposing the aircraft metallic faucet in a piranha solution; washing the aircraft metallic faucet; coating a surface of the aircraft metallic faucet with a hybrid Si-Quat coating with crosslinkers; and curing the hybrid Si-Quat coating at a temperature between 60° C. (140° F.) and 100° C. (212° F.).
Claims19
A method of manufacturing an aircraft metallic faucet with an anti-microbial coating, the method comprising:
- disposing the aircraft metallic faucet in a heated acid bath and subsequently washing the aircraft metallic faucet;
- disposing the aircraft metallic faucet in a piranha solution;
- coating a surface of the aircraft metallic faucet with a Si-Quat coating, the Si-Quat coating including a Si-Quat that comprises one of (i) 1-octadecanaminium, N,N-dimethyl-N-(3-(trimethoxsil) propyl) chloride;
- (ii) 1-tetradecanaminium, N,N-dimethyl-N-(3 (trimethoxysilyl) propyl) chloride;
- (iii) 1-decanaminium, N-didecyl-N-methyl-N-(3-(trimethoxysilyl) propyl) chloride;
- and (iv) 1-ocatdecananminium, N,N-dimethyl-N-(3-(trihydroxysilyl) propyl) chloride.
A method of manufacturing an aircraft metallic faucet with a hybrid anti-microbial coating with crosslinkers, the method comprising:
- disposing the aircraft metallic faucet in at least one of a piranha solution and a second solution comprising tetraethoxysilane, oligomeric hydrolysate and subsequently washing the aircraft metallic faucet;
- coating a surface of the aircraft metallic faucet with a hybrid Si-Quat coating including the crosslinkers, the Si-Quat coating including a weight ratio of Si-Quat:alkoxysilanes of between 1:1 and 2:1, the Si-Quat including one of (i) 1-octadecanaminium, N,N-dimethyl-N-(3-(trimethoxsil) propyl) chloride;
- (ii) 1-tetradecanaminium, N,N-dimethyl-N-(3-(trimethoxysilyl) propyl) chloride;
- (iii) 1-decanaminium, N-didecyl-N-methyl-N-(3-(trimethoxysilyl) propyl) chloride;
- and (iv) 1-ocatdecananminium, N,N-dimethyl-N-(3-(trihydroxysilyl) propyl) chloride;
- and
- curing the hybrid Si-Quat coating at a temperature between 60° C. (140° F.) and 100° C. (212° F.).
