Summary
paste name on the wires
This is a servo, there is some sort of a hard white paste keep the 3 wires from moving around and accidentally touching each other. It appears to melt with heat. Does anyone know what it is? My guess is putty.

Thanks in advance

Looks like RTV. Hopefully they used electronics grade, since it looks like some metal on the wires is exposed.

It might also be hot-melt glue. That is a nice quick solution for an assembly line. For low voltage, they could use just about anything.

I have seen hot melt glue used in similar applications.

Color and texture looks like that on the old CRT's.
Same stuff? ie RTV.

Looks like it to me. Here is an application where we use electronics grade RTV to stabilize a 2.4GHz radio antenna cable in a product (opened up for inspection)...
