It protects high voltage components like transformers and motor windings from arc, moisture, and corrosion while delivering a tough, glossy finish. This HAPs-free formula adheres well to metals, glass, and plastics, making it an eco-friendly, professional-grade solution for demanding electrical insulation needs. ## 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: Say what? - Good product, seals well. Great for huffing too 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. ## Features - Meets UL EIS Standards - Insulates components circuits and assemblies in high voltage applications - insulates transformers, coils, motor windings, and various electric generator parts against arc. - easy to use and adheres well to many substrates - protects against corrosion and moisture ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BPB6XBMS | | Best Sellers Rank | #95,261 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,128 in Spray Paint | | Brand Name | MG Chemicals | | Compatible Material | Metals, Glass, Most common plastics | | Coverage | Arc, corrosion, and moisture protection | | Customer Reviews | 4.5 4.5 out of 5 stars (146) | | Finish Types | Gloss | | Included Components | MG Chemicals - 4226A Clear Insulating Varnish, 1L, Can | | Item Form | Liquid | | Item Type Name | Electrical Insulator | | Item Weight | 2 Pounds | | Liquid Volume | 945 Milliliters | | Manufacturer | MG Chemicals | | Manufacturer Part Number | 4226A-1L | | Manufacturer Warranty Description | warranty@mgchemicals.com | | Material Type | Polyurethane (PU) | | Model Number | 4226A-1L | | Recommended Uses For Product | Exterior, Interior | | UPC | 779008422687 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** MG Chemicals - **Finish Type:** Gloss - **Item Weight:** 2 Pounds - **Material:** Polyurethane (PU) - **Recommended Uses For Product:** Exterior, Interior ## Images ![4226A Clear Insulating Varnish, 1 L Liquid Can - Image 1](https://m.media-amazon.com/images/I/71oL59bzZYL.jpg) ![4226A Clear Insulating Varnish, 1 L Liquid Can - Image 2](https://m.media-amazon.com/images/I/712Afwaw1cL.jpg) ![4226A Clear Insulating Varnish, 1 L Liquid Can - Image 3](https://m.media-amazon.com/images/I/81A5qsGte9L.jpg) ![4226A Clear Insulating Varnish, 1 L Liquid Can - Image 4](https://m.media-amazon.com/images/I/81FNx6CPCnL.jpg) ![4226A Clear Insulating Varnish, 1 L Liquid Can - Image 5](https://m.media-amazon.com/images/I/71t8WI-zDjL.jpg) ## Available Options This product comes in different **Size, Style** options. ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Say what? *by S***E on February 13, 2026* Good product, seals well.

I used this on a 5 cylinder, homemade, fiber distributor cap on a one-off handmade 5 cylinder radial outboard motor that hadn't run in over 30 years. It appeared there was some high voltage leakage from the center electrode to the 5 electrodes to the spark plugs so I sanded the carbon traces and coated the entire cap with this stuff. It worked. ## Frequently Bought Together - MG Chemicals 4226A Clear Insulating Varnish, 1 L Liquid Can - BNTECHGO 20 AWG Magnet Wire - Enameled Copper Wire - Enameled Magnet Winding Wire - 1.0 lb - 0.0315" Diameter 1 Spool Coil Red Temperature Rating 155℃ Widely Used for Transformers Inductors --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/509187530-4226a-clear-insulating-varnish-1-l-liquid-can](https://www.desertcart.gr/products/509187530-4226a-clear-insulating-varnish-1-l-liquid-can) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-10*
