WonderMask PX temporary, peelable, latex solder mask reportedly dries in half the time of other solder masks. Is hand applicable and withstands fluxing, wave soldering and cleaning operations. Is said to effectively mask and protect open through-holes and underside components in wave soldering processes, withstanding temperatures up to 650°F. Can be used as a conformal coatings mask. Has strong tensile strength when fully cured, and peels easily, even under harsh conditions.
