Hi Guys,

If one uses silicon based glue make sure it is neutral cure ( non acidic cure ) otherwise some corrosion of the copper wire in the loop may occur…I found a web site that talks about this:

Note that the silicone rubber used MUST be neutral cure where electronics or corrosion sensitive components are used. “Normal” SR is acid cure and releases acetic acid during setting (smells like vinegar). This is “not too bad” in many cases but can cause corrosion in sensitive applications.
Neutral cure silicone rubbers are widely available, and cost little if any extra. Most are “Oxeme” cure and release oxemes and methyl alcohol. The former may cause corrosion of bare copper. Oxeme cure not suitable for polycarbonate – use alcohol cure.
