MG Chemicals 4226A Clear Insulating Varnish, 55 ml Liquid Bottle

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.

Works just as it says! Easy to use.

Excellent product. Much better looking than the red corona dope. Easy to apply, and stopped a high voltage arc as advertised.

works perfectly as described. comes with no useful information on usage, drying/cure times, or cleanup. information is only in the listing images, or on the manufacturers website. can by handled after 1 hours, and needs 10 hours to fully cure/dry. cleanup is with acetone.

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.

Worked great on my Denso alternator stator windings. Alternator was for a 2006 Toyota Camry 2.4L

i use this for sealing coils on guitar pickups. it does a good job. 2 oz doesn't seem like much, but its enough to test the product to see if i want to spend 70 on the big bottle.

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.

Questo isolante è l'ideale per mettere al sicuro collegamenti elettrici, impossibili da isolare, una volta asciugato crea come un tappo solido, usato per isolare i contatti di una vecchia bobina di una vespa, consigliato.

easy to apply and helps with high voltage. Use ventilation when applying.

Came on time and done the job

Expensive, but without alternative that I know of. We use it quite often at work for specialty coils. Don't breathe the vapoours of this thing!

Davvero un' ottimo prodotto, stesura perfetta e ottima l'essiccazione all'aria. Un peccato che non sono disponibili anche quantità da 500 ml e da 1 Litro.
