## Overview

MG Chemicals 4228A-55ML is a high-performance, red insulating varnish designed for electrical components. It offers excellent dielectric strength, fast room-temperature curing, and strong adhesion to metals, glass, and plastics. This HAPs-free formula protects against moisture and corrosion while providing a vivid red coating for easy inspection, making it ideal for restoring and safeguarding high-voltage parts like motor windings and transformer coils.

## Description

4228A is an easy-to-use, HAPs-free, 1-part, low-viscosity insulating varnish that cures at room temperature and adheres well to many substrates including metals, glass and most plastics. This varnish insulates high-voltage parts such as motor windings and transformer coils against arcing and discharge as well as protects metals from corrosion. The coating’s distinct red color helps operators easily inspect coating coverage; however, for a clearcoat option, consider the 4226A. For insulation class H protection, consider our 4228.

Review: Used on a electrially leaky distributor cap. - NIce stuff. 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.
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.
