MG Chemicals - 422C-55MLCA 422C Silicone Conformal Coating 55 mL Bottle

Easy to use and the additive that glows in UV light helps to ensure complete coverage. Very useful.

I have done no scientific testing whatsoever with this coating. I can’t tell you from real world experience of building 15 to 20 drones that this coating will extend the life of your components , it’s excellent with heat really good with moisture and it doesn’t stress out your boards when curing like some coatings . This stuff you can paint a board then handle the board and install it all in about 10 or 15 minutes I believe this is a must have if you live in the southern hemisphere of the United States for moisture alone. I have lost a lot of boards to wet grass on a crash. I can tell you that I also use this on my VTX’s , receivers ,GPS Antanas , LEDs whatever I have seen no downside to this product.. what I do is lightly paint the board when I receive, Then do my soldering ,and my installl ,my wire placement everything . Then test everything then Before I button it up I’ll paint the top side of the board for sure sometimes the bottom again just to help with things like loosing pads or wires and I use as a light glue to help wires stay in place . I’ve built a lot of drones and I believe this is a must have for a builders toolbox. This coating is easy to apply and really does go a long way before running out . Only downside was I gobed a bunch is USB port then had to clean it out befor I could connect to beta flight , but that was user error. What I do now is shove a little silly putty in the USB port before painting then pop the putty out when done . I highly recommend this product . The odor is strong use in well ventilated area .

Great product. Had an issue with moisture contact to my controls, shutting down my washing machine . Quick, cheap solution!!

Works exactly how it’s intended to

So this does an incredible job at waterproofing especially when it comes to high wattage electronics and protecting them. I used this on an FPV drone and didn’t experience any overheating or anything of that nature. Something to note is that the oils in your hand can degrade this waterproofing. If you touch it more than likely it will flake off so after you apply it you should use gloves and put the piece in an area where it won’t be touched anymore and it will stay. Other than that great product!!

This stuff is easy to use, cures fast, and withstands a fair bit of heat and different chemicals. Been using this stuff for a long time professionally in a dip method, but recently wanted to experiment with it for personal projects. I can confirm it will spray from an airbrush (0.3mm needle) if you work quickly and clean the airbrush with acetone immediately. The documentation states no thinner is necessary when spraying, and while this is true, be warned that speed is the game to play. So plan your coverage before hand and try to pour as much as you need into the spray cup before starting. Then quickly apply it and clean the airbrush before it starts to cure.

Wow! This was exactly what I needed to finish up a project that I was working on. This stuff is next to impossible to find locally anymore, and this particular brand works very well. You get what you pay for when it comes to this stuff so buy the best! Thank you Amazon for making this available!

Other than the smell (volatile chemicals ya know?) this stuff is great!! It dries pretty quick, about 30 mins to 1hr depending on how thick you lay it down. I think it's 24hrs to cure fully. I did two coats on my FC and had to solder through it shortly after it cured, well it went fine. Then I touched up the solder joints and it was ready to go in short order. The fluorescent glow is a nice touch, just make sure you've got a UV torch of some type.

Simple to use and super effective!

Top-quality conformal coating for the FC ESC VTX camera/dve board and reciever on my GepRC TinyGo 4k and iFlight Nazgul xl5. I wouldn't dunk them in water but I'm confident they can handle a puddle snow or rain.

Conforming silicone is a versatile product. This one comes sealed in a container and works well.

It applies well and dries fast. Works better when appliying a generous coat; the end result just looks better.

I've crashed in a water , snow and mud but with this on my electronics (applied properly) I've had zero issues and have remained flying within moments of crashing , get a black light to ensure full coverage ****my review is for anyone looking to waterproof their RC vehicles or aircrafts/drones
