MG Chemicals offers a comprehensive range of acrylic conformal coating products designed to protect printed circuit boards (PCBs) from moisture, humidity, dust, fungus, and high voltage arcing. These 1-part coatings are considered to be one of the best ways to protect PCBs from humidity, moisture, and common contaminants.
They are certified to UL94 V-0, UL746E, and IPC-CC-830 standards. All coatings are available in both liquid and aerosol spray formats, and include recommended dilutions for compatibility with selective coating equipment.
We also offer silicone, polyurethane, and UV conformal coatings.

419D is a fast drying, acrylic based circuit board protective coating that cures to a durable, flexible and smooth finish. This 1-part circuit board coating is easy to apply and can be handled in 10 minutes. It can be readily removed with appropriate strippers, or soldered through for repair or rework.
419E is a premium acrylic PCB coating, designed to enhance PCBs environmental protection. This PCB protective coating is one of the few coatings on the market that is certified to both UL 746E and IPC CC 830C. The circuit board conformal coating is easy to apply, dries in 15 minutes, and cures to a flexible, smooth finish. The cured coating is not difficult to remove with appropriate strippers or solder through for repair or rework.
Acrylic is one of the most used types of conformal coating owing to its ease-of-use, options for rework and moisture protection. The coatings endure a host of environmental conditions including extreme temperature ranges, rain and high humidity. The polymeric film is highly flexible, conforming to the parts of electronic devices.

Acrylic conformal coatings are easy-to-use, 1-part coatings that cure by physical drying. These coatings impart excellent dielectric properties and protect against moisture, dust and fungus.
Acrylic conformal coatings provide circuits with excellent protection against moisture, dust and fungus. Their main advantages over other conformal coating chemistries are their cost, ease-of-use, and ability to be reworked.
The biggest shortcoming of acrylic conformal coatings is their lack of chemical resistance. While they excel in protecting against moisture, dust and fungus in relatively mild environments, they lack the crosslink density required to shield against more aggressive chemicals, such as fuel vapors. To ensure that you have the right conformal coating solution, it is important that you know all of your application’s requirements. If you are uncertain, please contact MG chemicals technical support for assistance ([email protected]).
Acrylics are thermoplastic resins, which means that while they have many strengths as protective coatings, they do not hold up well against solvents. But for that same reason, acrylic conformal coatings can be removed simply by using common solvents like acetone or n-butyl acetate.
Polyurethanes are excellent coating materials as they are highly flexible, provide great protection against moisture, and have excellent dielectric properties. Compared to acrylics, polyurethanes provide superior protection from abrasion and solvents; however, processing must be carefully considered because they take considerably longer to cure.

Silicones make great conformal materials thanks to their superior moisture protection, low modulus and extended temperature limits, giving them an advantage over every other conformal coating resin type. That being said, they are not ideal materials for high humidity environments, and compared to acrylics they struggle to adhere to certain substrates. As with every application, carefully consider all of your requirements, and contact MG Chemicals technical support if assistance is needed. ([email protected])
Epoxies are exceptionally durable due to their hardness and solvent resistance. Compared to other materials, epoxies can withstand particularly harsh environments and are thus suitable for ruggedizing PCBs in places like oil fields, on marine freighters, or under engine hoods. That being said, processing epoxies can be cumbersome, as they require measuring, mixing, and careful monitoring of their pot life. By contrast, simple 1-part acrylic systems that require only thinning can be more robust. Carefully consider all of your requirements when choosing the right conformal coating for your application, and contact MG Chemicals technical support if you need any further assistance.
