MG Chemicals Premium Polyurethane Conformal Coating, 430mL (310g) Aerosol Can

Bought to preserve some 70's vintage PCBs with no solder-mask following a repair (and noticing a lot of fingerprints etched into the traces...)Goes on really nicely with good build-up, dries fully in a couple of hours without too much odour so I was able to use it indoors. I missed something on one board and was able to solder through the coating with no problems - no need to strip it or use a ton of flux.I've always avoided conformal coatings but would definitely use this again.

Based on the data sheet, this looks like a great product with moisture and mould protection, for your PC board. The downside is that it has a long cure time, if left unheated. I carefully warmed mine in a BBQ. Remember to mask your connectors before spraying.

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.

Très bon produit, c'est pas donnée mais la qualité est là.Ce vernis est idéal pour isoler les composants (circuit électronique) des perturbations externe du aux variations de température, l'humidité ...Il s'applique bien avec l'aérosol et permet avec une bombe de couvrir une belle surface.En 2-3 couches, c'est déjà bien épais et ça protège vraiment bien. Attention, une fois appliqué ça ne bouge plus, donc difficile à enlever.Attention à la buse qui se bouche vite car le vernis est épais. Ne pas respirer les émanations bien entendu.

The company offers acrylic, urethane and epoxy products for electronics board protection or other uses. I choose the urethane as it's more durable than the acrylic but not as tough as the epoxy. Urethane is very durable and thicker and flows well. The urethane base rests in the middle regards cost and durability. Have used these products before and work well. I will be spraying a dishwasher circuit board that is known for moisture buildup and then developing shorts. This product is good for cheap preventative maintenance. No complaints.

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.
