This coating is formulated for use in sensitive applications such as manufacturing semiconductors. Thinner than potting compounds, it flows easily into small spaces between electrical components. The coating begins to harden when exposed to UV light. Use it to secure and insulate hardware on printed circuit boards. It requires a gun (sold separately) to dispense.

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.

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.

Clear enough to read through, this UV-resistant potting compound allows optimal light transmission for use with LEDs, solar cells, and fiber optics. Use it to encase electronic assemblies for protection from dust, moisture, mechanical shock, and vibration.
