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.
