Sprayable Anti-Static Coatings for Vacuum Components

[TheSergeant]

Has anyone attempted to make their own anti-static hose? I ran across this product, which is basically a sprayable carbon conductive coating that literally etches and embeds itself into plastics. 

I've been wanting to build my own UDD from a spare classic sys-4 I have laying around but static concerns kept me from doing it.  This seems like it would be an excellent way to make something like the Bosch 35mm hose and standard dust deputy anti-static.

Has anyone tried this?

Get any old anti static clothing "wrinkle release" spray. You'll need to keep applying it. I do this to all kinds of tools, especially when working with PVC materials. Also, DRY silicone spray keeps dust and such sliding off. Another good one is PG2000 available at Amazon or woodcraft.

I'm curious on this one, I'd love to have the flexibility of the Bosch 35mm hose, and have it be anti-static. [member=59237]TheSergeant[/member] , you'll have to be the guinea pig on this one.

Since you'd be spraying the outside of the hose, with all of the ridges, I wonder if you'd actually be able to get a consistent enough coating to get continuity. There's also the question of coverage. At 35mm diameter, you'd be able to cover about 7m of hose, but that is assuming it is smooth. Since the hose has a lot of ridges, I'd imagine the surface area of the outside is at least doubled, so you would need two cans to do one coat on a single hose.

I do love the idea of the homemade dust deputy, though. It seems like it would be perfect for that.

Brice, I've had the Bosch anti static hose (Amazon - Bosch 5-Meter Anti-Static Hose 35mm) for a couple years and it works great.  I did not like the connectors so replaced them with the Festool ends.  I  ended up with about $135.00 from Amazon.  I'm interested in trying the conductive spray on the two steel Oneida Dust Deputies I use.

For a DIY type dust deputy, try cooper tape. No need to reapply any coating. Make a complete static circuit from inlet to outlet.

I'm curious, your Steel DD's should conduct static electricity with no help needed. You have an Anti-Static hose.
What are you looking to do more with the spray?  [blink]

i'm surprised no one has tried this stuff!  For the DD i figured I could spray it but a better solution might just be some copper tape like another poster mentioned.  I thought the real advantage to this stuff would be on flexible components like the hoses where copper tape isn't as practical.  Rather than coating the entire hose I was just going to spray like 1/3 of it with several heavy coats.  Beyond coating the two ends of the hose would there really be a need to coat the entire hose all they way around?  Once you get to the DD you can just use copper tape and spray the 2nd hose as well.  If durability and abrasion resistance is a concern you could just through one of those diy hose covers on there.   

I'm tempted to try this but I don't have a multimeter nice enough to test the resistance through the system.  I tried to my measure the resistance in my stock Festool hose and couldn't even get a reading.

All you're looking for is to have a complete path to ground, so spraying just a portion (as opposed to spraying all the way around) would do for the outside. However, just coating the outside of the hose will likely not be good enough -- you'll probably need a path to ground on the inside as well. And it seems to me that the inside of the hose would be difficult-to-impossible to coat properly.

I'd just pay the price for the anti-static hose.  [crying]

Bingo!
If there is a hose cover a small wire could be run inside the cover , with then only the copper tape at the ends to hold the wire and connect to the tool and vac.

Leaky, the steel versions are painted and insulate the unit.

What about running the tiny copper wire on the inside of the hose?
I wouldn't think it will make a difference in performance of the Ct ,just make sure the wire is held tight on the ends.
Just a thought,

Ah, been so long that I'd seen one in person, I had forgotten that. In that case, a small amount of paint removal or the addition of the cooper tape on the inside would still work a static path.
I also agree that rather than running cooper wire on the inside of a hose or applying a spray chemical , I'd just buy a AS hose.

The other problem, which I had forgotten is that the rubber connectors on the steel version are probably not conductive.  Or I can just remember not to touch the 20 gallon drum and cyclone.  Oh and these are sucked by two Fein extractors.

. If you take Cooper tape and wrap it around the lips/tubing of where a hose will be attached on an inlet or outlet fitting, you only need the hoses to have some static carrying ability
. Oneida asks you to do this with their Plastic bodied Dust Deputy's where the hoses are attached on the cyclone hose fittings .
