Ideal for professionals seeking reliable, fast, and scalable electronic protection.

## Description

422C Silicone Conformal Coating is a 1-part, acrylic-silicone blend conformal coating that cures to a durable, flexible and smooth finish. It is easy to apply and can be handled in only 10 minutes. It may be removed with appropriate strippers or soldered through for repair or rework.422C is designed for applications where both high service temperature and flexibility are required.It puts minimum stress on components during thermal cycling, making it ideal for applicationsthat involve a wide temperature range. It provides strong protection against moisture, corrosion, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge.Cure Instructions:Allow to dry at room temperature for 24 hours, or afterletting sit for 10 minutes, cure the coating in an ovenat one of these time/temperature options: 20 min @ 65 ˚C 10 min @ 85 ˚C.

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

## Questions & Answers

**Q: I have been using the 422B version of this product for years and have been completely happy with the results. How does the new 422C version compare?**
A: Works the same and was cheaper, package included 2 brushes for applying it.

**Q: Will this make a flexible coating for headphone wires?**
A: No, this product is for water proofing components on a board that is not exposed to regular handling or significant flexing. You need to look at heat shrink tubing or brush on insulation. Heat shrink tubing is probably the best choice depending on what you're trying to do.

**Q: Can you use this on an led light over an aquarium? is it toxic after it cures? how long does it last? do you have to keep reapplying it?**
A: I wouldn't put it in an aquarium's water just to be safe, but if trying to stop short circuits in a wet environment- that is what it does if applied correctly and completely covering circuitry, connections etc. Water doesn't seem to degrade an application by itself, physical wear from handling can happen, but it is very durable otherwise and not needing re-coating. Use UV light to see if coverage is complete as it Floreses blue/green so can inspect.

**Q: can i paint this on a motherboard to resurface if i scratched the green coating that covers a board?**
A: It will cover it to prevent any shorts, yes. It is conformal coating. I prefer the UV curable type, but it will work.

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.
