Coatings for Electronics
Also known as conformal coatings, these coatings protect circuit boards and other electronics from moisture, dust, and static. They’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely. Apply these coatings without needing a potting box or other container. You can remove them if necessary.
Acrylic and acrylic lacquer coatings are our thinnest option, so they’re the easiest to apply. They’ll also come off the easiest when you have to rework or repair your component—just use a solvent. These coatings dry in a day or less. Silicone coatings protect components over a wide range of temperatures. They’re also the most flexible of our conformal coatings, so they won’t crack from vibration. However, they’re thicker than acrylic coatings, so they’re more difficult to apply and remove.
Silicone/acrylic coatings combine the flexibility and temperature resistance of silicone with the thinness of acrylic for easy application. Use them in the environments you’d use silicone coatings, such as high-vibration and high-temperature areas.
Urethane coatings are the best choice for harsh environments. They have the best chemical resistance in our offering, and they’re extra hard for the best resistance to scrapes. Plus, they won’t crack in low temperatures. However, they aren’t as flexible as silicone coatings, so they’re worse at handling vibration. They’re also harder to apply than acrylic coatings because they’re thicker.
Coatings in a bottle come with a brush for touch-ups. Coatings in a pen are best for precise application. Use them to repair scratches and chips on components, or touch up areas you missed while coating. They’re also good for blocking off areas you don’t want solder to flow into.
Coatings with ultraviolet visibility show up under a black light, so you can easily check if you’ve applied them evenly.
Coatings that meet IPC-CC-830 are certified for use on circuit boards. Coatings that meet UL 94 V-0 have passed a test for flame retardance.
Coatings that cannot be sold to the listed areas are restricted due to VOCs (volatile organic compounds) regulations.

High-Temperature Coatings for Electronics
Even in furnace-like heat, these coatings protect your electronics from moisture, dust, and static. They withstand temperatures up to 270° higher than standard silicone coatings while remaining flexible enough to not crack and peel from vibration. Whether your circuit board is in a hot, humid shop or inside heavy machinery that heats up and vibrates, these coatings keep it protected. Made of silicone, they won’t cloud from humidity.
Also known as conformal coatings, they’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely. Simply spray these coatings on your device without needing a potting box or other container. They contain a UV indicator, so you can use a blacklight to check if they’ve been applied evenly. You can remove these coatings if necessary.
These coatings are IPC certified for use with circuit boards. For flame retardance, they meet UL 94 V-0. They cannot be sold in California or outside North America due to regulatory limits on VOCs.
