It cures quickly—handleable in 10 minutes and fully cured in 20—while withstanding temperatures up to 200°C. Its UV fluorescence enables easy inspection, and it's compatible with robotic application for precision and efficiency in industrial environments. ## 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 applications that 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 after letting sit for 10 minutes, cure the coating in an oven at one of these time/temperature options: • 20 min @ 65 ˚C • 10 min @ 85 ˚C ## Features - Protects electronics against moisture, corrosion, dirt, dust, thermal shock, short circuits,high-voltage arcing, and static discharge. - Maximum service temperature of 200 °C - Fluoresces under UV-A light - Easy to apply and can be handled in only 10 minutes - Validated for selective robotic coating equipment ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B085G42TGS | | Best Sellers Rank | #18,828 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #24 in Industrial Coatings | | Brand Name | MG Chemicals | | Color | clear or transparent | | Compatible Material | Ceramic | | Container Type | Bottle | | Customer Reviews | 4.7 4.7 out of 5 stars (1,061) 4.7 out of 5 stars | | Full Cure Time | 20 minutes | | Included Components | 2 Brushes | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Type Name | Protective Coating | | Item Weight | 50.7 g | | Manufacturer | MG Chemicals | | Material Type | Silicone | | Model | 422C-55MLCA | | Number Of Pieces | 1 | | Other Special Features Of The Product | Cold Resistant, Crack Resistant, Dries Clear, Fast Drying, Heat Resistant, Strong | | Part Number | 422C-55MLCA | | Specific Uses For Product | Industrial applications, high temperature environments, high humidity environments, corrosive environments | | Unit Count | 1.86 Fluid Ounces | | Upc | 779008422069 | | Viscosity Level | Medium | | Volume | 55 ml | | Warranty Description | warranty@mgchemicals.com | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** MG Chemicals - **Item Form:** Liquid - **Material:** Silicone - **Special Feature:** Cold Resistant, Crack Resistant, Dries Clear, Fast Drying, Heat Resistant, Strong ## Images ![MG Chemicals - 422C-55MLCA 422C Silicone Conformal Coating 55 mL Bottle - Image 1](https://m.media-amazon.com/images/I/61T26zUthBL.jpg) ![MG Chemicals - 422C-55MLCA 422C Silicone Conformal Coating 55 mL Bottle - Image 2](https://m.media-amazon.com/images/I/51xEe0QnaSL.jpg) ![MG Chemicals - 422C-55MLCA 422C Silicone Conformal Coating 55 mL Bottle - Image 3](https://m.media-amazon.com/images/I/81gaSMh3UbL.jpg) ![MG Chemicals - 422C-55MLCA 422C Silicone Conformal Coating 55 mL Bottle - Image 4](https://m.media-amazon.com/images/I/81JmSFld9sL.jpg) ![MG Chemicals - 422C-55MLCA 422C Silicone Conformal Coating 55 mL Bottle - Image 5](https://m.media-amazon.com/images/I/71+C38kvt2L.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This coding works really well in the building of quadcopters *by on Reviewed in the United States November 8, 2021* 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 . ### ⭐⭐⭐⭐⭐ The good stuff! *by on Reviewed in the United States May 3, 2026* Wow! This was exactly what I needed to finish up a project that I was working on. This stuff is next to impossible to find locally anymore, and this particular brand works very well. You get what you pay for when it comes to this stuff so buy the best! Thank you Amazon for making this available! ### ⭐⭐⭐⭐⭐ The weird smelling paint that saves your electronics *by on Reviewed in the United States July 31, 2026* A coating of this stuff will save you $$$ on your outdoor electronics.I personally use this stuff on my FPV drones and it has saved me before. Not a silver bullet, but good insurance.Just be mindful this stuff is definitely cancer juice, so don't be like me and apply it at your desk. Outside or under a fume hood is ideal. ## Frequently Bought Together - MG Chemicals - 422C-55MLCA 422C Silicone Conformal Coating 55 mL Bottle - Pro Grade - Acid Brushes - 36 Count 3/8 Inch Boar Hair Acid Flux Brushes - MG Chemicals - 8310-55ML 8310A Conformal Coating Stripper - Gel, 2 fl. oz Container (Does NOT Contain Methylene Chloride), Clear, 55mL Bottle (8310A-55ML) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/217802636-mg-chemicals-422c-55mlca-422c-silicone-conformal-coating-55-ml](https://www.desertcart.sg/products/217802636-mg-chemicals-422c-55mlca-422c-silicone-conformal-coating-55-ml) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-14*
