Scotchkote Electrical Coating FD, Fast-Drying Liquid, Flexible Sealant and Bonding Agent, Self-Contained Applicator, 15 oz. can

I served as an electronics technician in the US Navy from 1978 to 1986. We used this same product, over the scotch brand silicone, "Self-vulcanizing" tape on all connectors, the large cannon plugs, that connect cable to their communications equip, radars, etc. It is designed to act as a sealant over the tape I mentioned. The silicone tape is wrapped around the electrical connector as close to the body of the equipment the cable plugs into. the tape is then wrapped over itself (there was a green line in the middle of the silicone tape the Navy used to help with this) overlapping the edges of the tape to the layer of tape being covered in a spiral pattern around the connector then two-three inches onto the cable protruding out of the connector. Then a fairly thick coating of this Scotch-Kote material was brushed over the tape and allowed to dry. I will tell you, we had to cut-off and replace these two coverings every year but every time I cut the old covering, the connector underneath looked brand new! Absolutely no signs that slat-water or anything for that matter had penetrated the seal. I was very impressed and so when I had to coat some wires in my Ford F-150 pickup truck I had soldered together, I first covered the soldered connection with heat-shrink tubing. Then wrapped all three covered wires together with the silicone tape and coated with this scotch coat. After 3 years inside the engine compartment of my truck, about 9 inches away from my shielded exhaust pipe, the joint is still intact and flexible. I swear by this stuff and the silicone tape/Scotch-Kote combination. I have not tried it over regular vinyl electrical tape but that's what the manufacturer says it is designed for. If it's good enough for the Navy and their ships at sea in the worst weather you can imagine, it's good enough for me.

Learned about it in the Navy where high salt infused moisture is constantly eating away at electrical connectors. My only complaint is that the 15 oz can usually goes bad before it gets used up.

We use a ton of this stuff in an automotive repair shop. At $50/can, it's expensive but it goes a fairly long way and it truly is waterproof. It's much better than liquid electrical tape at actually sealing the connections.

I had called many & varied local suppliers looking for 3M's 'Scotchcoat #14853 Electrical Coating', which I've used for many years (for many different & specialty applications, along with the intended ones), and found it was 'No Longer Available'. So, being the fool, I bought a bottle-w/ a brush product, called 'liquid tape' - mfg'd by 'Gardener Bender' - that, the salesman swore by, and - later, I was 'swearing at it'. Stuff is just 'junk' as far as I'm concerned, - maybe it works for some. I checked the internet, and one of the suppliers that I 'called', told me this product is essentially the same, they (3M) had just changed the name to resolve some legal/shipping problems. Found a Co. that had a fair price, low shipping (do your research) and ordered some. And I'm pleased to say, that it does appear to 'indeed' be the same product. It looks the same & smells the same. Besides, even if it's slightly different, it'll work for me in the various applications I use it for; And, it'll still be far and away better than what I've seen out there (so far). It's one of those products you hope they never stop making.

Easy to apply, brush is included in the cap. Used two coats, dried within an hour to apply second coat. Remains flexible after drying. Used outside so smell was not a problem.

Arrived quick and was just as ordered

I had no previous experience using this kind of product so it was A little thinner than I expecteted. However I used it in conjunction with the special Linemans tape that adheres to the wire jacket and also to itself. I NICKED 2 HIGH VOLTAGE LINES UNDER GROUND. AFTER CLEANING AND DRYING THOROUGHLY I PAINTED 2 COATS OF (SCOTCHCKOTE) AND THEN WRAPPED 4 LAYERS LINEMANS TAPE THEN 2 MORE COATS OF SCOTCHKOTE AND 24 HOURS TO CURE. I HELPED THAT PROCESS WITH A HEAT GUN (ON LOW.) VERY PLEASED !

This product is to help seal out moisture as a topcoat to vinyl electrical tape. The original version apparently was mainly pine tar with solvents for marine cable splicing. From the product description: "Suitable for direct burial, direct water immersion or above ground applications." I've used it to improve weather sealing coaxial connector couplings on radio towers where the wind will eventually find a way to lift the cut end of the topmost layer of electrical tape and flap it around in the wind until it eventually loses its grip and unwinds.
