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

Exelente calidad

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 .

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.

Works as intended, coats well and is visible under a black light. Highly recommended for quad builds. Don't cheap out. Definitely use in a ventilated area.

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 product solved my maytag washer control panel issues. It dries quickly so be very precise with your application. If you make a mistake, acetone does take it off. Highly recommend over having to clean the contacts every 4-6 weeks!

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

This is the best conformal coating I’ve used

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.

It Dried fast and sticks to pretty much all surfaces, however make sure you use it in a ventilated area has when I used it in my room I got a headache and lightheaded💀

Well packaged, with brushes, seem a fair quantity for the price. Not tested yet, solder mask first.

Nice Product and Worked as intended

Easy to apply, dry in 10 min.
