It can transpire that some of these water dispersants may have an adverse effect on the torque values of a structural fitting with undesirable structural consequences.
If the threaded fastener is disassembled, and the water dispersant liquid allowed to coat the threads before they are torqued. In that situation, the threads must be clean and dry before torquing for assembly. This is because some means of torque measurment require predicable friction during assembly, and the lubricating properties of the water dispersant would result in wrong torque values, and probable over torquing. Otherwise, for assembled and undisturbed fasteners, the water dispersant will not affect correct torquing, if undisturbed.
ACF-50 is a well respected product. I know a salt water seaplane operator who, after much study, has chosen Ardrox AV 15.
