4223F-312G Premium Polyurethane Conformal Coating, 11 oz, Aerosol, Clear

I can't stress enough how valuable this conformal coating has been in safeguarding my PCBs, especially those I anticipate will be exposed to high humidity or outdoor conditions. In fact, I've made it a rule of thumb to apply conformal coating to virtually any outdoor PCB, regardless of whether it's in a covered location. The reason is simple – even humidity can be surprisingly corrosive over time, leading to damage in solder joints and sensitive components.Applying this conformal coating is a breeze, and I appreciate how user-friendly it is. It doesn't require a complicated application process, making it accessible even for those with limited experience in PCB protection. What truly sets it apart is its durability. Once applied, I can trust that it forms a reliable barrier against the elements, ensuring the longevity and performance of the PCB.In essence, this conformal coating has become an essential step in my PCB protection process, especially for any electronics exposed to outdoor or high-humidity environments. It's a cost-effective and practical solution that adds an extra layer of defense, ultimately extending the lifespan of valuable electronics. If you're looking to enhance the durability of your PCBs and safeguard them against humidity or outdoor conditions, I wholeheartedly recommend giving this conformal coating a try.

This stuff lays down a nice, fairly flat, fairly thick layer of poly coating. Great for waterproofing a board I was working on and reducing the effects of vibration.

Needs to be cured in an oven on low heat but it performed well and didn’t leave an odor or residue. Used on an RV heater board notorious for water damage. Applied this to the new board and it looks very well sealed and works great. Expect it to last much longer.

Easy to apply in even coatings. I use to protect PCB assembly for harsh corrosive environments. I apply in single coat a few mils thick and is dry enough to complete assembly in a few hours at room temperature. Highly recommended over acrylic types.

This stuff is impressive. It forms a very thin but durable protective barrier after curing for a couple minutes at 100C. It even survived 24hrs in pirhana solution with zero visible corrosion!Edit: 99% IPA works great for removing it if necessary. Let the PCB boil in the alcohol for 10-15 minutes and it can be scrubbed off with a toothbrush.

Used to spray a replacement circuit board on my max fan in my camper that may be subject to moisture contamination. So far no problems.

We use this for industrial controls production. It coats well, protects well. We heat it to 105c for 1.5 hours to cure. Its leaves a nice & thick coat, which can make re-work not as easy as some, but the protection more than makes up for it in our application. Regular conformal coating remover does work, as does 99% IPA, should you need to re-work and its not a situation where you can burn through. You will want full PPE to use this stuff though, including a full face respirator and OV cartridges. This is meant for industrial use only, so be aware of that for your PPE needs! This stuff has an incredible amount of fumes, but again, its intended for the industrial market.
