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.

Two-Part Silicone Potting Compounds
Encase electronic assemblies in a layer of silicone for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They’re also known as RTV (room-temperature vulcanizing).
Cartridge potting compound requires a gun (sold separately) to dispense; use it with the included mixer nozzle.

Optically Clear Epoxy Potting Compounds


Clear enough to read through, these UV-resistant potting compounds allow optimal light transmission for use with LEDs, solar cells, and fiber optics. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. All require a mixer nozzle and gun to dispense.
Loctite® ES1901™ comes with a mixer nozzle.

Heat-Transfer Potting Compounds
Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.
Cartridge potting compound requires a gun and mixer nozzle (each sold separately) to dispense.

Adjustable-Flexibility Heat-Transfer Potting Compounds


Mixing required—resin and hardener come in two separate jars or in a jar and syringe and must be combined before applying. Change the mix ratio of these heat-transfer potting compounds to achieve the right hardness for your application. They're formulated to draw heat away from sensitive electronic components, so they have higher thermal conductivity than standard potting compounds. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.
The size listed is the combined total of the two parts.

EMI Shielding Coatings for Electronics

Protect sensitive electronic parts, enclosures, and prototypes from electromagnetic interference (EMI) with these coatings. Since they’re conductive, they block EMI from disrupting electrical and data 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.
