• Fastest full cure
• Ideal for situations where a thick coat of mask is required
• Easily peelable
• Highest strength to avoid breakage
• Nonflammable

Prevents solder from flowing into contacts, terminals, screw heads, and plated through holes.

WonderMASK PX is a natural latex temporary solder mask that is specially formulated to cure in half the time of other masks. WonderMASK PX cures over its entire surface area, including where it adheres to the PCB. This allows it to be peeled quickly and easily when other masks are still sticky at the bottom. Even the thickest bead of mask cures completely.

WonderMASK® PX is a temporary, peelable, latex solder mask designed to dry in half the time of standard peelable solder masks. It is hand applied and can withstand fluxing, wave soldering and cleaning operations. It effectively masks and protects open through-holes and underside components in a wave soldering process, and can be used as a conformal coatings mask.

WonderMASK PX can remain on all areas of the board until ready for test, and then, be easily peeled away. In addition, WonderMASK PX is ideally suited for situations where a thick coat of mask is required. WonderMASK PX has been specially formulated to cure homogenously, virtually eliminating any limit on the deposition thickness.

WonderMASK PX is not recommended for use on bare copper as it contains a sufficient concentration of ammonia to cause discoloration. For use on bare copper, WonderMASK P (part # 2211) is recommended.
