Heavy Duty Light-Activated Coatings for Electronics
Thinner than potting compounds, these coatings flow easily into small spaces between electrical components. They require an ultraviolet curing lamp to reach full strength. Use them to secure and insulate hardware on printed circuit boards.
Syringe coatings require a gun (sold separately) to dispense.

Harsh Environment Coatings for Electronics
High humidity, harsh chemicals, water submersions, and salt are no match for these electronic coatings. They also resist UV light, so they’ll work outdoors. Use them on circuit boards, sensors, and LED drivers in heavy machinery. 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.
PVDF coatings are more flexible than epoxy coatings. They’re IPC certified for use on circuit boards. You can also use them to protect against corrosion on metal joints. To apply, brush or spray them on, or dip your components in.

Heavy Duty Heat-Transfer Coatings for Electronics
This thermally conductive coating keeps electrical components cool by dissipating heat. Use it to bond transformers, transistors, and other heat-generating components to printed circuit boards and heat sinks.

Protective Coatings for Circuit Boards
Shield circuit boards from flux, solder, conformal coatings, and high temperatures. Heat resistant up to 640° F, these temporary coatings are most often used to protect open through-holes and components during wave soldering. Coatings can also act as a short-term adhesive to keep parts in place when you’re soldering a two-sided SMT circuit board. An alternative to masking tapes that require cutting to shape, these gel coatings flow easily into small spaces and don’t leave a residue when removed. They’re also known as solder masks. Product regulations restrict sales to the listed jurisdictions/areas.
Choose wash-away coatings if you use a water-based cleaning process such as a batch or in-line cleaning system. Wash-away coatings with a one-hr. overall dry time are nonflammable. They’re not completely water soluble, so they can’t be used in closed-loop cleaning systems. Coatings with a two-hr. overall dry time are completely water soluble for use in closed-loop cleaning systems. They’re slightly flammable.
Choose peel-away coatings if you use a solvent-based cleaning process or don’t clean your circuit boards. Coatings with a 15-min. overall dry time cure more evenly than peel-away coatings with a one-hr. overall dry time, so they can be applied in thick layers. They’re also nonflammable. Peel-away coatings with a one-hr. overall dry time produce low odors because they don’t contain ammonia.

EMI/RFI Shielding Coatings for Electronics
Protect sensitive electronic parts, enclosures, and prototypes from electromagnetic interference (EMI) and radio frequency interference (RFI) with these coatings. Also known as conductive paint, these coatings block EMI and RFI from disrupting electrical, data, and radio signals, which can cause circuit malfunctioning and data loss.
For best adhesion, apply to clean, oil-free surfaces. If applying to highly chemical-resistant plastics such as PVC and PTFE, use a primer first.
Carbon acrylic coatings are made with ground carbon powder mixed with acrylic. They're best for RFI and low-frequency shielding applications, such as protecting jumpers and resistors in initial prototypes, since they're not as conductive as nickel and silver acrylic coatings. They don’t contain metal, so they’re also great for electronics where metal-filled coatings could cause malfunction, such as metal detectors.
Nickel acrylic coatings are made with nickel flakes mixed with acrylic. They’re the best in our offering for protecting magnetic components, since they absorb and redirect magnetic fields. While not as conductive as silver acrylic coatings, they still protect against a broad spectrum of EMI and RFI frequencies. Use them to repair small circuits on circuit boards and to coat devices such as meter and scanner housings. They have good corrosion resistance.
Silver acrylic coatings are made with silver flakes mixed with acrylic. They’re the most conductive coatings in our offering, so they protect against the broadest spectrum of EMI and RFI frequencies. They’re also the most corrosion resistant. Use them to coat portable electronics, access panels, industrial cabinets, and engine control modules.
Coatings that cannot be sold to the listed areas are restricted by product labeling requirements.
