MG Chemicals 422C Silicone Conformal Coating 55 mL Bottle: Perfect for Electronics Protection

RatishRatish: Wish they gave better brushes but non the less, good stuff, easy to apply, dries in 5-10 mins (thin layer). Gonna test the water resistance properties soon...

Electrosoft: 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

magefeb: J'aime le fait de voir où j'ai appliqué le produit. J'ai testé sur des sondes d'humidité et il y avait une belle démarcation violet une fois sec.

Il est facile d'en rajouter où il en manque par la suite.

Le temps me dira si le la longévité du produit est respectable.

Richard McCullough: I bought this product to coat a circuit board in my cooktop. I had to replace the board twice because a boil over on the stove seeped into the board and caused it to short out. I think this conformal coating is going to do the trick. It was easy to apply; it came with too small brushes. I thought this was a bit on the pricey side but was not able to find cheaper anywhere else. The only reason I didn't give this five stars is because the product did not come with instructions. I had to go to the MG Chemicals website and download the application directions.

Rich: 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.

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

Zae hoyteZae hoyte: 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

DadPops94: 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...

Kiran Doddigarla: Good overall. Need to be familiar with the technicalities and theory of things before deciding to use this as its silicone based, so the resultant coating will be kinda rubbery and can peel off easily with rough usage.
