The varnish is solvent-safe, free from hazardous air pollutants, and delivers a tough, glossy, and flexible transparent finish—perfect for professionals demanding reliable, eco-friendly electrical insulation.

## Description

4226A is a highly insulating varnish with excellent arc resistance. This dielectric coating is a low viscosity, 1-part coating that is easy to use and adheres well to many substrates. Dielectric coatings like 4226A protect high voltage parts such as transformers, coils, motor windings, and various electric generator parts against arc, corrosion, and moisture fouling. 4226A is free of hazardous air pollutant solvents (HAPs) such as xylene and toluene. For red insulating varnish, see 4228. Features & Benefits High dielectric strength – 3 000 V/mil Maintains dielectric protection under conditions of high humidity and high temperature Excellent finish – tough, flexible, glossy, and durable transparent coat Adheres to metals, glass, and most common plastics HAPs-free solvent system (no xylene, toluene, and MEK)

Review: Excellent for varnishing transformer coils - It worked great for varnishing the new coil in an induction heater after rewinding. It dries on its own but I put it in the oven anyway. Excellent product, I will buy again.
Review: Messy, tacky stuff that covers well - This stuff is pretty tacky to the touch, and let me tell you it is extremely difficult to clean off of anything it comes in contact with (from clothing to hands to your work surface) so be sure to wear gloves and protect things well when using it. Does not smell as bad as people claim in the reviews. Kind of like a mild nail polish. Coverage is pretty good. It could be thinned (as they even recommend) to be sure that it gets down into the windings better, but for the purposes of a simple restoration it works fine. The brushes they give you to apply it are pretty garbage though - pick up some better brushes made for oil-based paint. One thing I wish it had was instructions or directions along with it. They provide a small pamphlet with danger warnings, and the bottle itself again has warnings, but there are no instructions anywhere to be found. I had to return to this listing just to find the recommended cure time and information about application. They recommend going to the manufacturer's website for this info as well, but this should absolutely be included with the product itself.

## Questions & Answers

**Q: Can i use this at (loudspeaker) magnet voice coil winding? haw do you think? is it the better then   mg chemicals 4228 red glpt insulating varnish**
A: Yes, and it should not be a problem.  It has a much higher voltage insulation rating, however I used it in a 3000 volt transmitter power supply.  Your voice coil (not used as a power supply speaker choke coil) application can use either one.  Tony

**Q: Can be removed for resoldering?**
A: When cured/dried it is very tough and cannot be removed by any solvent I know of.  For de-soldering PCB's you can "burn through" the coating of a solder joint but be careful of the fumes/smoke.

**Q: What precautions should a hobbyist take when using Super Corona Dope at home?**
A: I have never used any extra precautions when using it.  I guess I would say be careful not to spill it as it is much more fluid that earlier versions of corona dope.

**Q: will this work on stater/alternator windings on a motorcycle magneto that is in oil? will it hold up to oil &heat?thanks**
A: long-term, probably not. If it's immersed in oil, I wouldn't think you'd need to coat the windings anyway
