I was wondering if anyone has had any experience with the different Resins available with how well they act as an electrical insulator. Long story short is that we are building a prototype bobbin for a high voltage transformer and curious on how well the insulation properties of the different resins would be. Would one be better than the other.

Types Available include:

Standard Resin

Tough Resin

Durable Resin

Clear Resin

Rubber Like Resin (Not Practical)

Heat Resistant Resin

Ceramic Filled Resin

Castable Resin (Not Practical)

Dental Resin (Not Practical)

What do you all think?
