My Take On Waterproofing with MG Chemicals Silicone Conformal Coating
Вставка
- Опубліковано 20 тра 2018
- It's almost common knowledge that silicone conformal coating is the way to go for waterproofing drones, racing quads and other electronics. Even though this video is based on the topic of drone racing, the information about using MG Chemicals Silicone Conformal Coating is good for many electronic applications. I mention that in case you arrive here and have little to no interest in drones. You can still use this video.
In the video I discuss some of the differences between Silicone Conformal Coating and Silicone Modified Conformal Coating. I also explain some of the best practices for prepping before application of the conformal coat as well as how to apply it correctly.
I also go over how you can strip some of the coating when you want to work on or replace a component, in case you are like me and would rather not simply solder right through the coating.

I spend a lot of time on Instagram and post a lot of unique stuff there. Please follow me on IG: / pinchtune - Наука та технологія
I used it while i was learning acro during winter in uk, it worked well sitting in wet grass and bush while hunting for your kwad.
Good video as always 👍😉
Silicone Modified Conformal Coating is a godsend for making expensive RC electronics water resistant!!!
P.s. I didn’t know about the UV thing, thanks allot. 🙏🙏🙏
Yes it is! You're welcome!
@@PinchTune Your sure the modified kind reacts to uv light???
Thanks
@@ryanjofre I recorded this video 5 years ago... so I don't remember if it's in this one, but I know I have footage where I show how I dry it more quickly. I use UV and a heat gun to dry it more quickly. Check my other videos on that channel. It's gotta be there somewhere. Be careful though. The heat gun can burn the coating. You want to heat it up a bit then just let it be, and then do it again maybe every 15 minutes.
I use it and it's worked great for me. I fly in deep snow conditions all winter and have yet to fry anything after many crashes. I coat everything with the modified stuff. I like the added confidence!
I know exactly what you're talking about. I buried my trusty Chameleon in snow this winter. Pulled it out. Blew some compressed air into it to blow out the snow and went right back up.
Very thorough explanation! Thank you very much good sir!
Thank you. Glad I could help. I'm very happy with how this video came out!
Thanks for all the info and tips!
Absolutely! Thanks for the feedback.
All of the benefits that you mentioned is spot on bro 💯% thanks noobs like me should take notes
Thanks. You know, I've been flying since 2014. Initially, I used to coat only some of the builds. But then, I had to remember which were coated and which weren't, in case I wanted to fly, say, the snow. Now I don't do that. I just coat every single build.
I went to cheap route and bought their acrylic based conformal coating last year. I didn't have any failures with electronics but it does dry harder of course, because it's acrylic and it can chip in places that are thin, and it does turn yellow.
After flying one of my GEPRC dolphins and losing some of the flight controller components yes it still flies I decided to use the acrylic and two flight controllers after that with the acrylic on it no components broke free or lost.
If nothing else it's kind of like putting a phone case on your phone.
I don't recommend the acrylic base.
I do recommend the silicone base only based upon other fpv Pilots testimonials.
Pro tip:
90% isopropyl alcohol works for the flux removal.
Loving it and yes, if you do not solder your wires beforehand you will plug the holes like he said and you'll have to get that out of there to make it work.
He's not doing it wrong, but I would solder the wires first and then you wouldn't have to worry about the conformal coating down in the holes because if you don't get it in the holes in the water gets in there you can have a rust problem.
Another trick I have learned to make sure the connections work for your cameras and accessories.
Plug them in first before you conformal coat.
Let it dry then you can unplug them if necessary and you have a better chance of your connection being clean & waterproof.
Oh and that last note the weather the temperature that makes a difference too if you're up north or down south you definitely want the silicone if you're on the equator where I am I don't think it's going to matter too much compared to where they are.
Thanks man. That was actually great feedback. I didn't know of anyone that has used acrylic until now... My bottle is still new. lol
@@PinchTune 😏👍 if you're still living in the same location geologically as you were as the filming of this video, you might as well just leave it on the shelf.😁
i ordered a bottle of mg chemicals silicone modified coating and it just arrived by UPS. thank you for the video. i got a total chinese motor scooter moped and i am going to install a motorcycle bluetooth stereo sound system on my bike as well as a burglar alarm and i am going to coat the circuit boards on both.
Hey, that sounds like a great plan. I'm sure it will help with he longevity of of it. Thanks.
George Janko look-a-like! When you looked at the camera I was like WAIT! He looks so familiar.
Lol. I admit I had to look him up. I'm skinnier now after 6 years so I look different.
@PinchTune still doing electronic work? Heck yeah he's a good dude
@@DaftKermitThePunk Hi, I am... but I'm mostly doing guitar stuff these days. I still have all my FPV stuff but have been putting all my time into music and water sports again. Like, here: ua-cam.com/channels/FyTdoHeYn7O2-XpHpI61Ww.html
can you just u se isopropyl alcohol to clean the flux?
Hey can we use it on a aquadrone which runs on water and has electronic circuits on it?
Do you also apply coating on the LEDs or should these also be avoided? If you use a naked gopro on the drone, I guess this should also be coated?
Dude, I know how to confirmal coat me quad meow. Thanks for the how to.
Thanks. Great to hear. I love that this video is really helping a lot of people.
Definitely going to try this stuff! On the topic of not seeing in fog because of the build up on the FPV camera, what about a little bit of RainX on the lens? I've never tried that either, but the shit does wonders for car windshields in any rain, so maybe the same for the FPV lens!
I tried Rain X, I tried Ceramic Pro... on lenses. Neither work in fog. Apart from the dude that made a mechanical wiper for his lens with a servo, I don't think there's anything that'll work for that.
@@PinchTune - Damn, I was hoping that might work. The next big thing is a FPV camera lens that repells mist and rain!
Do you do both sides of every component? You only did the one side. Thank you
look up Paryloc that specializes in waterproofing electronics. located in Pico Rivera, CA
I'm about to coat my ESC board, should the EMI shield be removed?
Nice. Build video and parts list for the newbeedrone?
Thanks. The parts list is simple. AcroBee V2 (this one is DSMX), with a basic Cockroach frame and gold motors. These have the white King Kong props, but I got them right before they released the new Candy Props. I also use the NewBeeDrone Nitro Nectar 1S batteries.
I just hot glued plugs to waterprooof them with actually permanently attaching them
I’m debating if I should use this on my dji airunit
Yeah, I don't know about that. I haven't tried that. I've been flying my DJI units as they come. Maybe one day I'll do it on one. I don't really expect any problems. But I haven't been flying in wet areas lately so I haven't bothered yet.
I would think it would get hot...
I'm here looking to use this stuff on my gpu for sub-ambient liquid cooling, fyi.
I can see that being fine. I mean, we use it for drones, but I'm sure MG Chemicals made this stuff mostly for computers.
Awesome, any experience/comparisions with the acrylic stuff?
I actually have a full bottle of the acrylic stuff. I haven't opened it yet. Lol. So... no idea. I bet it works too. But since the silicone stuff has worked wonders for me, I don't like that change what works.
@@PinchTune Agreed. I actually did more searching today and yes, silicone is better in my opinion as a result. They are also used on automotive stuff ALL the time. I had a big can of MG premium acrylic for years but it's time to switch.

cat meows :3
I want to put liquid metal on the CPU and GPU of my laptop. Around the chips there are very small resistors or capacitors, not exactly sure what they are. My question is, will this coating protect the PCB if the liquid metal happens to spill out a bit?
Probably...
It may, but you’re better off using masking tape to completely mask off the surrounding inch or two around the die (CPU/GPU chip). This is how to pros do it. Do some UA-cam research, you’ll see what I mean.
Hi does epoxy stick to already coated pieces ?
Probably not very well if you're looking for a really strong bond. But if you don't need a super strong bond you might be OK. I've never tried that though.
hi i just bought this after watching your video, after applying the coating.. if the drone gets dirty.. can i still use isopropyl alcohol to clean it? or will it clean away the silicone coating?
It you clean very lightly with alcohol it will soften the coating, but it will harden up again once it's dry. However, if you do scrub a bit, the iso alcohol will take the coating off. You might need to recoat where you cleaned.
@@PinchTune thank u for the explanation!! I guess i'll have to clean my dirty quads with water after applying the conformal coating 🤣
@@mrboiboi2 I do clean them with alcohol and Q-tips. You'll see there's a point where too much is too much. I can usually get away with cleaning with alcohol and not strip away the coating.
@@PinchTune my area here is full of mud and grass, i crashed 2 times into muddy puddle and flowing drain.. fried 1 esc and 1 FC, hopefully this silicone conformal coating can prevent tt from happening next time 🤣
@@mrboiboi2 Ah yes, I don't know what grass is. Never seen it. Lol. All sand and dry dirt over here. But we do get snow at my place. And I fly conformally coated quads over the stuff.
I use clear nail polish on my brushed builds cause I’m broke ha . It rained on me tonight in California and I was lucky I just coated my micro cause I crashed before I could land back Inside my house through the window so it landed in the damp dirt while it was raining still , I fly from inside my 2story house , I mounted a video RX 15 feet off top of my house about 40 feet off the ground and that gives me amazing fpv video when I’m flying from inside , now I just need crossfire module and nothing can stop me from going to the moon !
Haha, I mean, technically nail polish would be fine. Plus, micros don't get that hot. Them main benefit of silicone is the flexibility and the heat resistance. Plus, I can take off silicone with flux remover or even alcohol. I think nail polish is acrylic if I'm not mistaken, so you need something stronger like acetone... which is bad for plastic parts. Just a thought.
PinchTune yes your totally right , I’m still flying brushed builds cause I’m new to the hobby , started in January this year , I’m confident enough to build my first brushless quad for my birthday also this coming January so the game will Change for me and I will not put nail polish on thoes builds ,im gunna buy the MG chemicals as shown here . I like your channel btw I’ve learned a lot from you about this hobby , flying has really grown on me its cause i am a “ tinkerer “ & I enjoy building them and making them neat and tidy it’s just fun “ except the crashes ...
What is your setup? Groundstation or something?
I have the MG Silicone Conformal Coating with the Black text on the Label, there is no green. Same thing?
Will this work for the iPod shuffle?
Acrylic vs silicone ? On the web it's not always clear which one to use
I have a bottle of acrylic that I bought in a pinch because I couldn't find the silicone at Fry's that one day. But I've never used it. To my understanding, silicone will take higher temperatures... but both should do a similar job on low temperatures PCBs.
@@PinchTune I was trying to understand if Acrylic was a harder-setting, thicker, more durable coating: as the Silicone is removable with rubbing alcohol...
@@Towardrisk It might well be. I just don't know. I personally like that I can take the silicone coating off with alcohol or flux remover... because I don't like it there when I'm working solder joint. I actually, rub it off with a Q-tip and flux remover, then resolder, clean, and reapply.
@Admiral Krang Good to know. I have a bottle there and have never even broken the seal. I don't like to change what works, and silicone works great.
@PinchTune Why don’t you cover the back side of the pcb?
I made this video years ago... so I don't remember what it has exactly, but I do coat the back too. But I wait for one side to dry first. It's possible in the video I had previously coated the other side. Thanks for watching, Danny.
Do I have to remove flux residues before applying conformal coating ?
You should
You should remove flux even if you aren't coating.
Has anyone experimented with clear coat sprays such as Krylon makes? Or any others that you can easily get at a hardware store?
It will be difficult (or impossible) to solder through, and can only be removed with strong solvents, such as acetone, which would also damage the components on the board. So definitely a NO GO.
Any body know how to remove the coating ?
You can solder through it easily, But looks like he also said we can use flex remover and spray it in a little cup and then use a Q-tip to clean whatever you need
how is this stuff for LED sealing?
I think it's fine. It resists heat pretty well. Do keep in mind some powerful LEDs get really got. Maybe be careful with those.
@@PinchTune heats not the problem, the panel only gets 55c warm. What im concerned of is energy/flux loss.

I live in Poland and buy 422b in company Praud.pl.
thnx!
Yup...I use a lot!! >_< lol
So... Anyone melted one doing this?
Melted what?
This is useless shit. Fried already 3 stm32 on fc and esc. I do not realize how you cover all the fc's stm32 legs, with only 1 coat. It's just goes down to the bottom of the stm and not covering the legs. I tried 5 coats to get a result. And after landing in the river the fc died. And how to waterproof the connectors? The only way I think is to use a polyurethane glue that is used for gluing shoes
That’s a bit of blanket statement. You could argue with the hundreds, if not thousands of FPV pilots that coat their rigs. Plus, the voltages we run don’t tend to fry electronics when they get wet, so long as it isn’t saltwater. Plus, all this stuff does is increase your chances of survival when stuff gets wet. It doesn’t mean it’ll completely save you every time. Conformally coated or not, you take a big risk sticking electronics in water. That’s just common sense.
@@PinchTune I'm an engineer and just have only two statements in my mind when something is coated: isolated or not isolated.
