With a robust dielectric strength of 3000 V/mil, it protects transformers, coils, and motor windings from arc, corona discharge, moisture, and corrosion. Its low-viscosity, easy-to-apply formula adheres to a wide range of substrates, providing a durable, glossy finish without hazardous solvents. Trusted by professionals for reliable, long-lasting insulation. ## Description 4226A is a highly insulating varnish with excellent arc and corona 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, corona discharge, 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: The best corona dope found. - This is basically the same formulation that the SPRAYON red insulating spray uses. The chemical formulation gets rid of the vaporous liquid carrier and leaves a thin crust of highly resistant varnish that has excellent corona protection. I use it for corona dope and to seal hardware after torquing. Review: Great product - Works just as it says! Easy to use. ## 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 and corona. - easy to use and adheres well to many substrates - protects against corrosion and moisture ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BMNR4L3F | | Best Sellers Rank | #151,590 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #154 in Household Polyurethanes, Shellac & Varnish | | Brand | MG Chemicals | | Brand Name | MG Chemicals | | Compatible Material | electrical insulation materials | | Coverage | 0.055 square meters | | Customer Reviews | 4.6 out of 5 stars 166 Reviews | | Finish Type | Gloss | | Finish Types | Gloss | | Item Form | Liquid | | Item Type Name | Electrical Insulator | | Item Weight | 0.17 kg | | Liquid Volume | 55 ml | | Manufacturer | MG Chemicals | | Manufacturer Part Number | 4226A-55ML | | Manufacturer Warranty Description | warranty@mgchemicals.com | | Material | Polyurethane (PU) | | Material Type | Polyurethane (PU) | | Model Number | 4226A-55ML | | UPC | 779008422663 | ## Product Details - **Brand:** MG Chemicals - **Finish Type:** Gloss - **Item Weight:** 0.17 Kilograms - **Liquid Volume:** 55 Milliliters - **Material:** Polyurethane (PU) ## Images ![MG Chemicals 4226A Clear Insulating Varnish, 55 ml Liquid Bottle - Image 1](https://m.media-amazon.com/images/I/71q8nUDLgFL.jpg) ![MG Chemicals 4226A Clear Insulating Varnish, 55 ml Liquid Bottle - Image 2](https://m.media-amazon.com/images/I/712Afwaw1cL.jpg) ![MG Chemicals 4226A Clear Insulating Varnish, 55 ml Liquid Bottle - Image 3](https://m.media-amazon.com/images/I/71t8WI-zDjL.jpg) ![MG Chemicals 4226A Clear Insulating Varnish, 55 ml Liquid Bottle - Image 4](https://m.media-amazon.com/images/I/81KDtHfb-1L.jpg) ![MG Chemicals 4226A Clear Insulating Varnish, 55 ml Liquid Bottle - Image 5](https://m.media-amazon.com/images/I/81RtYy8StwL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The best corona dope found. *by H***D on June 25, 2026* This is basically the same formulation that the SPRAYON red insulating spray uses.
