Ambersil 30235-400ml Acrylic Conformal Coating Anti Corosion PCB's

Great product I used it on new Max Air fan motherboards during installation, to prevent a known problem of water/condensation issue before it happens, now two years on I can confirm no issues on the motherboards.

Good stuff, works well, does what it says on the tin

I broke/shorted my amplifier on a new car I got. It is a common issue with the model of car however I did contribute to this particular disaster by somehow letting 3L of coolant leak in the boot of my car. The horizontally placed amplifier did not enjoy that. Upon research of the damage caused I stumbled upon opinion stating that this item is very good at protecting electronics from condensation and I suppose, with a few coats, from direct water contact. I was very wary about spraying a liquid onto the circuit board. Other than isopropyl alcohol that is... After removing all the interior, cleaning the board, testing (it somehow worked) and reading lots of advice I bought this item to complete a repair above and beyond to protect my (probably already damaged) amplifier. I have attached a few photos documenting the issue. But the main point is, this item seems to work. It dries with a nice lacquer like feel to it. I sprayed it on the most vulnerable parts and let it dry. For future reference or anyone wondering, car is BMW 2 series, Harman system.

As I run a very cold system which creates condensation I needed a solution for this problem of water cooled systems and found it right here with this product made for this problem, important please remember to cover all the connections ie: fan pins, m2s, pcie,internal usb's etc in fact every connection you are going to use on your motherboard before using this as it's very hard to remove once its applied, apply 2coats to your motherboard first before adding other parts of your system, once these have been added use again on the completed system and I mean everything to stop any condensation everywhere as is of great importance to your whole PC

Perfect for protecting circuit boards

Pretty good stuff for protecting electronic boards but even 3 coats sees no appreciable build up. Have not tried units yet so can't comment if performance is impacted (assuming not)

We kept getting slugs come into our metal electrical boxes despite putting pellets down and trying to seal every nook and cranny. We had two shorts, lucky the board survived. We then cleaned it with alcohol and then sprayed this stuff on. Small coats and built up a good layer on the back and front of the board. No issues so far and seems to have done its job. Make sure you turn off all equipment first and allow to dry (couple of hours to fully harden).

The BMW mini has an issue with the circuit boards in the roof (centre console) getting wet and failing from condensation. on getting new ones from an ebay based breakers yard i used Ambersil 30235-400ml Acrylic Conformal Coating to coat the circuit boards (mask off the connectors first) and it drys nice and quick, allowing for repeat coats until you are satisfied with the finish. no issues since, but need a winter to be sure. However this is the stuff the electronics industry uses for exactly this purpose so im not worried.
