With a low volume resistivity of 6.82 x 10⁻⁴ Ω·cm, it offers broad frequency protection while adhering excellently to multiple surfaces including drywall and plastics. Ready-to-use and eco-friendly, this metallic finish coating cures in 24 hours and is ideal for architectural, electronic, and musical instrument applications where interference elimination is critical. ## Description The 843WB Super shield water based silver coated copper conductive coating is a one-part urethane system pigmented with highly conductive silver coated copper flake. It is easy to use, with no let-down, and no heat cure necessary. It can be applied by spray, brush, or roller. The cured coating is smooth, durable, and adheres well to plastics, wood, metal, and ceramics. It also bonds well to drywall and can be painted over with common Architectural paints. Applications & usages: this coating provides highly effective EMI/RFI shielding across a broad range of frequencies in Architectural and electronic applications. Water based conductive paints are the only choice for Architectural RFI shielding applications because VOC regulations prohibit the use of solvent based systems. Such applications include containing RFI within a room such as an engine room to prevent interference across other rooms. Also, it can be used to protect a room containing sensitive electronic equipment from general sources of interference, such as Server rooms, recording studios, laboratories, and surgical rooms, especially those near cell phone or radio towers. This product is also great for providing EMI/RFI shielding to electronic Enclosures, sensors, Test equipment, portable controllers, communication devices, and most applications where one would normally use solvent based shielding. This product also good for repairing conductive traces and electronic prototyping. Review: works great! here's some tips! - I've never worked with shielding/conductive paint before, but did a fair amount of research and asking questions before jumping in. After looking at a few other brands of shielding paint, I went with this because it didn't seem cheap, but it didn't seem overpriced either. I am not recommending this as a better alternative to any brand or method. Just how this worked for me. I can speak a little to the process, but do your own research and be sure to practice safety precautions. Trust but verify anything I say here. The two project guitars are different enough, I think it's worth mentioning. Both had a spray finish applied, the mahogany body with nitrocellulose (purple), the ash body with polyurethane (red). Both also had some sort of either grain/pore filler or base coat applied as well. Inevitably, some of this would get into the cavities, so I got to see how this paint interacted with the different types of wood and also the types of finishes. If you just pop this open and start applying it, you're going to have a bad time. Get a respirator or heavy duty paint mask at least, gloves, and a good bit of lighting (I used a headlamp). Get your guitar ready to apply the conductive paint by making sure ANYTHING you don't want to get this stuff on is covered. Have a clean lint free cloth on hand to clean up splash and spills. Do not use a cloth to apply this by hand. Get some paint brushes, dip them deep in the mixture and kind of stir it up a bit each time. Then brush the tip against the inner rim of the jar to get off any excess that might drip. Apply it evenly to your guitar cavity. You can use the brush in an upward angle on the edges and just let it ever so slightly slide over the rim of the cavity (1mm or less). Let it dry 3 hours. Do 3 coats. Let it dry at least overnight, if not a whole 24 hours. I won't go into making sure everything is grounded properly - that's more nuanced than I have time for, but I hope this helps. Like all conductive paint, it does splash easily, although I've seen a couple of other brands in action that looked more prone to splatter. If you do spill some, dab and DO NOT wipe if you can help it. Wiping could scratch your guitar. If it's not fully dry, you can also scrape it away with even just a nail (but use gloves). Worked great, did the job really well and looks great. It's a dull, dark metallic gray. Wear that paint mask for your safety but also because this stuff smells pretty rotten until it dries. Review: Works great for guitar shielding! - I’ve got a first year of production MIJ 1997 ESP Viper, which I love dearly. We recently moved and when I got back around to setting up my home studio again, I was getting a horrendous amount of buzz from my guitar. I mean, it was so bad that it was interfering with notes as they sustained out. No amount of repositioning myself in relation to my desk, monitor, ANYTHING, helped. After double checking all of the guitar wiring and grounds, unplugging everything in the room one by one, unplugging my router, etc.; I still wanted to yank my hair out. Now, if you know ESP, then you know that they’re some fine craftsman. Again, this is an ESP handmade in the Japanese facility back in the 90s. It’s not an LTD. Not that there’s anything wrong with LTD. It’s just apples and oranges. But, there was zero shielding anywhere in the guitar, except for some foil tape on the backside of the control cavity cover. I ordered this out of desperation really. My Hail Mary. It’s a small 12ml bottle, but there was enough for me to do 3 thick coats in all 3 cavities = the 2 pickup cavities and the control cavity. When you mix it, use something like a popsicle stick. If there’s any clumps, smash them with the stick until they break up. Stir well. Wipe the areas that you’ll paint with some alcohol. I did scuff the cavities with some sandpaper as best as I could beforehand, then used some compressed air to blow them out. Then the alcohol. Then mixed the paint again. Paint color is like a charcoal silver. I thought that I would prefer black, but I actually like the charcoal color because it’s easier to see if you missed any spots IMHO. Everything cleans up easily with a wet rag. Dry time between coats is around 15 minutes or so, depending on how thick your coats are. I didn’t rush it. Over the course of a couple hours I took my time to paint coats until the bottle ran out. As mentioned, 3 thick coats in all cavities. Instructions state that it takes 24 hours to fully cure. After about 5-6 hours, everything was plenty dry for me to put my pickups and pots and wiring back in. Then restring and adjust everything. And of course I couldn’t wait. So… I was floored. 90% of the noise was gone. Not only that, but I could now actually reposition myself and get the electrical interference noise to go away 100%! But here’s the kicker. After the paint had fully cured after 24 hours or so? The guitar is now dead silent. No repositioning needed. It works! ## Features - Provides excellent EMI/RFI shielding over a broad range of frequencies - Volume resistivity of 6. 82 x 10(-4) Ω·cm - One-part, ready-to-use system—no dilution required.

I would expect a product this expensive to be sealed from the factory.** A: Yes. The package I received has a small piece of scotch tape on the sides. Probably added by the seller to prevent the plastic outer package opening up in transit. 👍 The actual container jar inside was in perfect condition. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works great! here's some tips! *by M***D on July 2, 2025* I've never worked with shielding/conductive paint before, but did a fair amount of research and asking questions before jumping in.

Check the specs *by A***R on September 27, 2025* Top quality paint. Check the specs. Many brands and types out there. All with varying specs and performance. Just wish had a little more in the bottle. Just made do with multiple coats on a strat. ## Frequently Bought Together - MG Chemicals 843WB-15ML Super Shield Water Based Silver Coated CopperConductive Print, light metallic brown - ALDON Copper (II) Sulfate Solution, 1M, 500mL - The Curated Chemical Collection - Pure Copper Anode Sheet 2Pcs 99.95% Purity Copper Electrode Strip for Copper Electroplating and Jewelry Plating 0.04''x1''x6''(1mmx25mmx150mm) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/67527148-mg-chemicals-843wb-15ml-super-shield-water-based-silver-coated](https://www.desertcart.us/products/67527148-mg-chemicals-843wb-15ml-super-shield-water-based-silver-coated) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-09*
