Alternator was for a 2006 Toyota Camry 2.4L ## 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 | #150,664 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,757 in Spray Paint | | Brand | MG Chemicals | | Brand Name | MG Chemicals | | Compatible Material | Metals, Glass, Most common plastics | | Coverage | Arc, corrosion, and moisture protection | | Customer Reviews | 4.6 out of 5 stars 164 Reviews | | Finish Type | Gloss | | Finish Types | Gloss | | Item Form | Liquid | | Item Type Name | Electrical Insulator | | Liquid Volume | 945 Milliliters | | Manufacturer | MG Chemicals | | Manufacturer Part Number | 4226A-1L | | Manufacturer Warranty Description | warranty@mgchemicals.com | | Material | Polyurethane (PU) | | Material Type | Polyurethane (PU) | | Model Number | 4226A-1L | | Recommended Uses For Product | Exterior, Interior | | UPC | 779008422687 | | Unit Count | 33.814 Fluid Ounces | ## Product Details - **Brand:** MG Chemicals - **Finish Type:** Gloss - **Item Weight:** 2 Pounds - **Material:** Polyurethane (PU) - **Recommended Uses For Product:** Exterior, Interior ## Images ![MG Chemicals 4226A Clear Insulating Varnish, 1 L Liquid Can - Image 1](https://m.media-amazon.com/images/I/71oL59bzZYL.jpg) ![MG Chemicals 4226A Clear Insulating Varnish, 1 L Liquid Can - Image 2](https://m.media-amazon.com/images/I/712Afwaw1cL.jpg) ![MG Chemicals 4226A Clear Insulating Varnish, 1 L Liquid Can - Image 3](https://m.media-amazon.com/images/I/81A5qsGte9L.jpg) ![MG Chemicals 4226A Clear Insulating Varnish, 1 L Liquid Can - Image 4](https://m.media-amazon.com/images/I/81FNx6CPCnL.jpg) ![MG Chemicals 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 ### ⭐⭐⭐⭐⭐ Excellent Product *by W***T on May 2, 2026* Excellent product.
