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

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 .

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!

A coating of this stuff will save you $$$ on your outdoor electronics.I personally use this stuff on my FPV drones and it has saved me before. Not a silver bullet, but good insurance.Just be mindful this stuff is definitely cancer juice, so don't be like me and apply it at your desk. Outside or under a fume hood is ideal.

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

I used this to protect the small micro components around my RX 7800 XT die in prep for kryosheet and other conductive solutions. I did 2 small coats. This stuff flows great, it got into all the nooks and quickly became tacky. I tried to use the included brush, but I needed a bit more accuracy so I just cut the swab off a qtip and dipped the stick in the bottle and blotted the area I need protected, this worked perfectly. If you read the material sheet it takes 24 hours to cure at room temp with a brush on application. At 60c 20 minutes, and 80c 10 minutes. I cured 2 layers with a blow dryer on low and it took around 10 minutes with constant heat. After curing I did add a conductive kryosheet over the die and everything was good to go.This stuff (422c) shows with neon with UV light as well. This makes it easy to see if you missed any spots.1 bottle will probably last 2-3 lifetimes.

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!!

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

I use this mainly on PCBs, robotics, GPUs and CPUs to protect delicate parts from external infiltration or electrical conduction.I definitely like the redesigned bottle and application approach as their old black top bottles with the brush attached to the underside would somehow catch air and become stuck and brittle and eventually crack and break which would slowly (or quickly) dry out the SCC.The new bottles seem to have fixed that problem and the brush(es) are not external of the container itself.The SCC itself is the same tried and true MG Chemicals magic and applies, dries and works as always. It is my go to and has been for quite some time.5/5

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

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.

Simple to use and super effective!

Easy to apply, dry in 10 min.

Used as painting coatings…works great
