The technical question to Eric Foster.

[mrand]

I have a coil 380mm diameter, probably from the detector SuperScan. Photo 1. There is very good and universal (2.4ohm/490uH). At present, I use her with other detector PI.
On the second photo is visible as beautifully looks her flooding. Eric, whether you can remind which resin then you used? I took a little sample which after heating emits the scent similar to the phenol. Your answer is very important and I wait for her. I greet

I renew the question. Probably passed unheeded.

Mrand, the only material that I know of that's ever been used to embed searchcoils in the manner shown in the photo, is epoxy resin. (I'm not Eric, but I've been involved in many searchcoil designs for several different companies over 29 years.)

Sorry but I missed this as I was away at the time. The coil is not one of my manufacture, so I am not sure what resin was used. I always use a viscosity lowering spray when the shell is filled, which ensures that the resin adheres to the shell wall with no gap as the picture shows.

Thanks for the answer and explanations.

For such a repair use a good 2 part Epoxy resin. Usually comes in small tubes which you then squeeze and mix however much you want. Make sure the surfaces to be repaired are dry and clean. Rough up with a piece of medium grade sandpaper helps the resin adhere.
